How to Wire a 3-Way Switch: Wiring Diagram - Dengarden

Dan has been a licensed journey-level electrician for some 17 years. He has in depth revel in in most areas of the electrical industry.

A "3-way switch" is really two switches that both control one gentle. This representation makes it look easy, but this article explains the intricacies of wiring a 3-way switch.

Wiring a 3-Way Switch

Wiring a 3-way mild switch is not a hard activity... there are simplest 3 connections to be made, in spite of everything. Making them at the correct position is a little more difficult, but nonetheless inside the features of most homeowners, if any individual displays them how. That's where working out a wiring diagram can assist.

First, what's a three-way switch?

When you want in an effort to control a mild from two different places (for instance, you want so that you could flip the stair lighting on from both upstairs and downstairs), that is what electricians name a "three-way switch."

Is it hard to twine a 3-way switch?

To replace a switch isn't tricky in any respect: Simply watch how you disconnect the old one after which put the wires again on the new mild switch in the same position. Problems can rise up when an extra switch is being added or for those who omit which wire went where. That's when it becomes necessary to grasp a bit more about how a 3-way switch works and learn how to read a wiring diagram.

What do I need to know sooner than I begin?

If you realize what the purpose of every cord is, the duty will turn out to be a lot more effective. This article will give an explanation for everything you'll want to know with a view to cord a 3-way switch, with wiring diagrams and commonplace wiring methods defined.

What about 4-way switches?

Read How to Wire a 4-Way Switch for instructions and wiring diagrams for wiring four-way switches.

How to Wire a Three-Way Switch

Not all 3-way switches are the same. Choose which configuration you need to observe by means of looking on the diagrams supplied beneath. If you're ranging from scratch, Diagram #3 may well be the most efficient position to start, however these strategies can be used interchangeably in old paintings. They merely indicate other ways to run the vital cables. Diagram #1 works when a number of lighting fixtures percentage one common breaker, and the switches are both on the same wall. Diagram #2 works absolute best when chronic is available in the ceiling but the switch containers are on reverse walls—it is frequently more straightforward to run the cable up into the ceiling mild box as an alternative of between switches. Diagram #3 works perfect for circumstances with a couple of switches in the same box, as different switches then have continual available and will operate other lights without having to have a separate chronic in line run to them. Diagram #Four can be helpful when the light is close to the first switch box. It results in a lot of wires, so putting in a larger field may be vital. Turn off the ability at your electrical panel before you start operating. Make positive you understand which screw terminals and which wires serve which function. Below, you'll be able to find complete descriptions to guide you. Have numerous 14-3 kind NM cable available, which has three insulated wires—white, black, and crimson—plus a bare copper floor twine. If you might be connecting to 12-gauge twine, or the breaker is 20 amp, you can use 12-3, instead. Most house lighting circuits are 15 amp, which handiest calls for 14 gauge cord. Follow the diagram to attach the wires (see instructions beneath) to the new three-way switch. All white wires used as travelers between the 3-way switches should have their ends wrapped with black electric tape or in a plastic cord nut.

How a 3-Way Switch Works: Identifying the Terminal Screws

There are three screw terminals on the aspects of the switch and one at the end. Every switch has these identical 3 terminals, however older switches may well be lacking the fourth floor terminal. The small, inexperienced screw terminal on the finish is the ground terminal. It is normally painted inexperienced, even though the image does no longer display that color well. It can incessantly be known because the screw that is part of the steel framework of the switch and isn't insulated from other steel parts. The inexperienced or uninsulated ground wire always goes to this floor terminal. Older switches frequently didn't have this floor terminal screw, but are now not legal to make use of. Now, all light switches will have to have a floor terminal screw to attach the bottom cord to. One of the 3 different terminals is a distinct color, normally darker, and is known as the typical terminal. Mechanically and electrically, this not unusual terminal is connected internally to probably the most other two brass screws known as the traveler terminals. When the switch is flipped the opposite direction, that connection is damaged, and the average terminal is then connected, internally, to the other traveler terminal. The not unusual terminal is at all times attached internally to at least one (however just one) of the traveler terminals. Which one relies on whether or not the switch is up or down. It should in all probability be famous that the traveler terminals are essentially interchangeable. Given that every one is to have a traveler wire hooked up to it, and there are two traveler wires and terminals, it doesn't matter which traveler cord goes to which traveler terminal.

Identifying the Ground, Common, and Traveler Terminals in a 3-Way Switch

The common terminal is at the best in this view, with a traveler at the lower end. The floor terminal screw is appearing up as silver-colored on the very bottom.WildernessAn old switch. This switch has no ground terminal/screw and is not criminal to make use of. Make certain your switch has a floor terminal.Wilderness

Which wire is "hot"? Which screw is the "ground"?

Identifying the Screw Terminals by means of Color

What is the fairway terminal screw?

The small, green screw terminal at the backside is the bottom terminal. All new switches must have a floor, but some older ones do not.

What is the darker screw terminal?

One of the 3 screw terminals will probably be a special color, most often darker. This is the common terminal.

What are the brass screws?

The two brass screw terminals are the traveler terminals.

Identifying the Wires by Color

What is the fairway twine?

The inexperienced or uninsulated (copper) ground cord at all times is going to the ground terminal.

What is the white twine?

The white twine is the neutral. You'll package all of the neutrals along side a "wire nut" or a twist-on plastic twine connector.

What is the black twine?

The black wire is "hot" at all times except all the circuit is became off on the circuit breaker panel.

A be aware about wire colours: The National Electric Code calls for that each neutral cord be coloured white, and that floor wires be coloured inexperienced. Only neutral wires may be white in color, however the code makes an exception for white wires in a cable that are not getting used for a neutral. These wires will have to be colored black the usage of a magic marker or some other method. Many electricians will do this, but many is not going to, and it may possibly make troubleshooting at some point tough and can be a protection danger to anyone else working on the device. I encourage you to take the few seconds necessary to paint these non-neutral wires.

The colors shown in these wiring diagrams are not unusual color usages most effective. Not all electricians use the similar colour code (with the exception of for neutrals and grounds), so the wires may well be other colors.

Identifying All the Parts of a 3-Way Light Switch

The terms "traveler" and "common" have already been defined, however there are different terms that will likely be used in this article that also want some rationalization.

Cable. The time period "cable" refers to an mixture of two or more wires, bundled together, most often in a sheath of insulating material. Each twine is insulated one at a time, with the imaginable exception of the ground wire. The floor wire is also insulated with a green colour or left naked (copper), without insulation. Power in. The power-in cable is that cable that finally leads to the circuit breaker panel or fuse box. It is the cable that gives the power to the lights system. Neutral. This is the white twine contained in the power-in cable. It does now not terminate at or connect with any switch, despite the fact that it may be found in a switch field and ended with a cord nut that connects it to any other impartial cord. Ground. The grounded wire in each and every switch or light fixture field. It is either colored inexperienced or left naked of insulation (copper). Hot twine. This is the second one, black twine, contained within the power-in cable. It is "hot" always until the entire circuit is grew to become off at the circuit breaker panel. Circuit breaker panel. Commonly referred to as a "fuse box," it is going to include either circuit breakers or fuses. This panel controls the entire chronic within the building and it is where that persistent could also be close off. Two rope. "Two rope" is the designation given to a cable that has two particular person wires, plus a ground wire. These wires will be coloured white and black, with a inexperienced or naked (copper) floor. Three rope. Three rope is a cable with 3 wires, plus a ground. Normally the colors are white, black, and pink with an extra inexperienced or naked (copper) floor.

Understanding a Wiring Diagram

Each diagram will show the two 3-way switches (however no longer the wall field they are contained in), the quite a lot of cables and wires used within the configuration being mentioned, and the sunshine field and light-weight fixture.

How does the electricity drift through the switch?

To understand the wiring diagram, you must know that the electrical present enters the device on the black cord in the power-in cable, passes in the course of the switches, through the mild fixture, and returns to the white twine within the persistent in cable. If the circuit is broken anywhere (a switch grew to become the mistaken manner, a damaged cord, or a bad mild bulb), the present will not float and the bulb won't light. For dialogue purposes, each and every 3-way switch will probably be thought to be to have the typical terminal attached to the right-hand traveler terminal when within the "up" position and hooked up to the left-hand terminal when within the "down" place. This is not essentially true, alternatively, it is merely useful for dialogue purposes.

Read the descriptions moderately and evaluate them to the diagrams to know the diagrams. Each diagram may have a description of ways the present travels with a purpose to mild the lamp.

Voltage Testers

A non-contact voltage tester is an invaluable device right here for operating on electrical circuits. Both Fluke and Klein make professional-quality testers, and cheaper ones are regularly available as well. As a qualified electrician for some 20 years, there may be always one in my pocket, and anyone operating round electrical energy should lift one as smartly.

Turn off the ability prior to beginning to paintings!

Installing the Light Switch

Once the correct location of each and every twine is decided using the wiring diagrams under, the light switch is connected to proper wires and put in in the mild switch box. Make sure the ability is off earlier than making any connections!

Older switches vs. newer ones:

Many residential gentle switches have a small hollow at the back of the switch that wires can be pushed into, and all switches have the screws at the aspect. The picture of the older switch above has each the push-in holes and screws; the opposite is a dear switch that has holes to insert cord but the screws will have to be tightened as well. Many switches have only the screws, with no holes. There is a "strip gage" at the again of the switch; it displays how a lot insulation is to be stripped off if the push-in way of connection is for use. If the screws are for use, a little more insulation must be removed.

How to connect the wires to the screw terminals:If the screws are to be used for connection, bend the end of the stripped cord into a half circle the use of needle-nose pliers, and wrap the wire across the screw in the clockwise direction. Tighten each screw firmly. Fold the wires smartly back into the wall box and push the switch into the box. Normally the bottom screw goes down, toward the floor, but it may be inserted within the up place with 3-way and 4-way switches.

3 Way Wiring Diagram #1

3-way switch wiring diagram with the power-in cable coming into the light field.

Wiring Diagram #1, Power In the Light Box

In this example, the power-in cable enters the light field. This approach of operating the cord is not unusual when a number of lighting fixtures percentage one commonplace breaker, and the switches are both at the same wall. Cables need to be run into the sunshine box, between the 2 switches, and from the light box to simply probably the most switches.

Lets apply the current because it lights the lamp within the light fixture:

The current enters the sunshine field on a black cord, because it all the time does. That twine is spliced to a white cord in a two-rope cable that goes to the primary switch box (now not the switch), the place it is spliced to the white cord in a three rope cable and continues on to the second switch, at the not unusual terminal. If the switch is up, it is going to exit the switch at the right-hand traveler terminal and continue on the crimson cord again to the traveler terminal at the first switch. If that switch is also up, it is going to exit that switch from the typical terminal on the black wire within the two rope cable from the light switch. Continuing down that black cord, the electricity enters the sunshine field the place it is going to the light fixture. The present will pass in the course of the gentle, exiting at the white, neutral twine and returning to the power-in cable.

A observe concerning the color of the wires: In this example, the only neutral wires are the white wire in the "power-in" cable (which is at all times a white wire) and one of the crucial two wires attached to the light (also always white). All other white wires should be colored.

3-Way Wiring Diagram #2

3-way switch wiring: Power within the mild field with 3 rope cables to each and every switch field.

Wiring Diagram #2, Power in Light Box

In this 3-way switch wiring diagram, the power-in line enters the light box, but 3 rope cables are then put in between the sunshine field and every switch box. This means might be used when power is to be had within the ceiling but switch boxes are on opposite partitions—it is incessantly easier to run the cable up into the ceiling gentle field as a substitute of between switches.

If the present is adopted...

it comes into the sunshine box on the black wire then flows to the common terminal on one switch the use of a (coloured) white cord it exits the switch from a traveler terminal then returns to the light box, where it is simply spliced to some other wire that goes to a traveler terminal on the second switch it goes thru that switch, again exiting from the common terminal, and once more enters the light box, where it is going to the light itself. The neutral is going from the power-in cable directly to the light fixture.

3-Way Wiring Diagram #3

3-way wiring diagram with persistent entering switch #1.

Wiring Diagram #3

This time the electrician has introduced continual into the first switch, thru the second one switch, and on to the sunshine fixture. This is an affordable manner for instances with a couple of switches in the similar box, as different switches then have power available and will function other lighting fixtures with no need to have a separate power in line run to them.

The primary distinction this is that the neutral from the power-in line needs to be taken to the light fixture via the 3 rope. The white twine will have to be used right here, as code requires that each one neutral wires be white.

Following the current...

it enters the first switch box on the black wire and is hooked up to the average terminal. If the switch is in the "down" position, it exits the switch at the crimson cord, entering the second one switch at a traveler terminal. If that switch may be down, it exits that switch on the black, common, cord and continues to the light. After passing during the light fixture, the current returns to the second one switch field on the white cord, is spliced to every other white wire within the 3 rope used between switch packing containers, and continues to the primary switch box, the place it's spliced to the white continual in twine and again to the fuse box. The circuit is entire and the lamp will mild.

3-Way Wiring Diagram #4

3-way wiring: Power-in enters switch #1 along side a cable to the sunshine field.

Wiring Diagram #4

This example displays the power-in cable coming into the primary switch box along with the cable to the light fixture. This can result in numerous wires on this field, however will also be useful when the sunshine is near the first switch box. A bigger field could also be important to include the entire wires.

Following the present...

it enters the switch field at the black twine at the common terminal. If the switch is up, it's going to go out the field at the pink traveler cord and proceed to the traveler terminal at the second switch. If that switch is also up, it's going to go out the switch at the commonplace terminal on the white (colored) twine and go back to the primary switch box the place it's spliced to the black wire within the 2 rope going to the light. Passing throughout the lamp, it returns at the white (neutral) twine to the primary switch field, where it is spliced to the white (neutral) wire returning to the fuse box. The circuit is entire and the lamp lighting fixtures up.

Commonality In All Wiring Diagrams

Common to all of those wiring diagrams is that the neutral, white wire from the lamp connects immediately to the white, impartial wire from the power-in cable without ever terminating on a switch. It may or will not be spliced to any other white twine in a field, however by no means terminates on a switch—only on the gentle fixture. The black power-in wire all the time is going to the common on a switch, ceaselessly "changing colors" in the course of the necessity of splicing to different cables. No matter what color, one switch may have a commonplace terminal attached immediately to the power-in black cord. The other common terminal on the different switch at all times goes immediately (despite the fact that perhaps back spliced) to the light fixture. It does now not terminate on the different switch. There are two traveler wires; they at all times cross immediately from one switch to the opposite. Neither traveler wire ever terminates at the mild fixture, the flexibility in cable, or on the rest however a traveler terminal, despite the fact that it may splice to another cable somewhere. Neutral wires are at all times white, and white wires now not connected to the white continual in twine must be colored every other colour. Ground wires are at all times green or bare of insulation (copper). Each switch, as well as the light fixture, must have a floor twine terminated to it. The most effective exception is older homes that shouldn't have floor wires within the boxes; if there is a ground twine within the box it should be terminated on the switch and lightweight. A last notice about construction codes:

Recent code adjustments require that each and every switch box have a neutral wire in it. This means no longer just a white cord, but a white twine that is attached to the white wire at the chronic in cable. This rule is intended to offer long run capacity for the use of a dimmer or different instrument that may wish a neutral cord and forestall homeowners from disconnecting or using the bottom twine for other functions. New work (equivalent to including a new three-way switch) will need to agree to this code.

Which approach or diagram is the most productive to observe?

The best wiring diagram proven right here this is felony to use is #3, even if #1 might be changed via including a 2-wire cable from the lower field to the sunshine. Any neutrals within the switch field that are unused are either spliced together or, with regards to a unmarried neutral, merely capped off with a twine nut and tucked back into the box.

Am I required to exchange the entire wiring that doesn't meet the current code?

Simply replacing a switch does not mean that the room must be re-wired, as the prevailing wiring is "grandfathered in" and is acceptable. Old paintings does no longer want to be re-done to comply with the code and is this why the unacceptable (by way of present code) wiring diagrams are discussed right here in this article.

Questions & Answers

Question: Can a dimmer switch be installed in a three-way switch arrange?

Answer: Yes, however a 3-way dimmer switch must be used. Most dimmer switches will not work.

Question: Is there a 3 manner switch diagram with three lighting fixtures in the circuit?

Answer: To upload more lighting fixtures merely use the same wires that to the prevailing fixture and prolong them further to alternatively many additional fixtures you want. Simply splice new twine into the twine going to the present light. They will all come on and off at the same time.

Question: On a three-way switch, can it simply be grounded in the box, or does it wish to move to the box after which to the switch? Can it simply go to the box? My house is wired simply to the field, however I've been told it should additionally pass to the switch.

Answer: Current electrical code calls for that every one switches be grounded. It is easy enough to add a short "pigtail" from the field to the switch, if the field is metal and already grounded.

Question: My three-way switch is over fifty-years-old. There is a white cord on one side of the field (at the backside), and a purple twine at the same facet(best). On the other aspect, there's a black wire (top). The new three-way switch field has a inexperienced screw at the backside on one aspect, and a black screw on the other side on the backside, with two gold-colored screws on the top. Can I connect the wires to the brand new box in the same place because the old, without reference to colours?

Answer: Yes, however you did not mention a floor cord (at the green screw) for the previous switch. It's very doubtful it has one. If no longer, the new switch will have to get a floor cord to that inexperienced screw, which can mean finding a supply for a ground wire and running it to that switch. Electrical code requires each and every switch have a floor wire now even though grounds weren't used for a few years.

Other than that, hook up the wires the similar manner. The worst case situation is that the switch is not going to work properly, after that you are going to change a few wires and try back until it DOES work as it should be.

It's at all times fun trying to decipher what an electrician or house owner did fifty years ago!

Question: I have a setup that appears like “3 Way Diagram #1,” in line with the configuration of the 2 switches (I haven’t positioned the lightbox but), but when I separated both switches from the wires, all of the traveler traces went hot. The white wire “power-in” cable remained scorching, as neatly. How can this happen? Is it imaginable that that is if truth be told a 4 method, and I’ve just failed to identify an additional switch?

Answer: As traveler wires move from one traveler terminal on one switch to a traveler terminal at the other switch, it's not possible to take away both ends from the switches and feature the wire be sizzling. It isn't connected to the rest at all, and cannot be hot.

What more or less tester are you using to determine if a wire is scorching? The non-contact testers mentioned within the article will also be delicate enough to select up static electrical energy transferred from one wire to any other even though they are not touching. They are supposed to ensure a cord is dead, and I've by no means had one give a false damaging (appearing a dead twine), however the fee is that every now and then they are able to show scorching when a wire isn't.

If the wires are hot when disconnected, then there may be some other source of continual that you haven't known yet, and the wires are going somewhere you're ignorant of. It is in doubt that it is a 4-way switch - those have four terminals on them (plus floor), and they are all vacationers. No chronic line must ever terminate on a 4-way switch.

Question: Can you direct me to a diagram of a 3-way switches configuration?

Answer: There is a hyperlink near the beginning of the object on 3-way switches. Here it is back: https://dengarden.com/home-improvement/How-to-wire...

Question: If I understand appropriately, one - and just one - of the traveler wires is all the time hot. If that's true, may one put an outlet in the course of every traveler wire with the results of one outlet or the other - however not both - being 'ON'?

Answer: You may just do this, however only one switch - the only with the flexibility from the fuse box - will operate them. You may just even set it up so the top or the bottom of a unmarried outlet, but not both, is on, relying on how the switch is flipped. You will have to make certain that there is a neutral cord run with the others and to be had at each and every outlet.

Question: I've the situation pictured in diagram 1 of this newsletter and I've long gone through my wiring numerous instances and it still doesn't work. I'd be positive I've it right kind nevertheless it doesn't paintings. How can I further diagnose my wiring downside?

Answer: Is the breaker on and the light bulb just right? Is the make-up within the lightbox proper? If you set the incoming black wire to the sunshine bulb, does it illuminate? If all the ones are good, the best guess is that either the black or the white from the lightbox isn't attached to a "common" terminal, however one of the traveler terminals. It is all the time possible that one of the vital switches is unhealthy as neatly - even emblem new switches may also be defective.

If you could have a voltmeter, preferably a non-contact tester, you can troubleshoot it as smartly. Using the twine colours within the diagram, the white cord at the switch will have to be sizzling at all times. One traveler or the opposite at that very same switch should be scorching, changing as the switch is flipped. If all that works, and the vacationers on the different switch cross sizzling or cold as the primary switch is flipped, the black wire on the other switch must be sizzling or not, as that switch is flipped. Checking these must inform you the place the problem is.

Question: Can I exploit a 3-way switch with simply two wires?

Answer: No. There will have to be 3 wires between the 2 switches. You CAN use the switch with best two wires, but it is going to act as a regular switch, not a three-way switch.

Question: I’m in need of to switch from a normal gentle switch to the rocking gentle switch. I've 2 black wires and one red cord - the place should they move?

Answer: If you are simply changing a typical mild switch with some of the "decora" style (a sq. switch that just rocks up and down) then the wires go to the same place they did at the wall switch.

Question: How do I strip some insulation off the wire?

Answer: Preferably with a twine stripping tool. If one isn't available a knife can be used even a pointy cooking knife. Cut across the insulation, being very cautious not to touch the copper twine, and then strip a line down one side. Wire cutters can also be used by twisting them around the most sensible end of the reduce after which the use of them to push off the insulation you want removed. Again considerable care must be taken to not injury the cord inside of. Either method, if the wire is nicked it should be cut off and the method started over.

Use any of the diagrams above, and easily hook the wires to each other. Black to black, white to white and floor to ground for as many lighting fixtures as you want to.

Dan Harmon (writer) from Boise, Idaho on January 21, 2019:

@George:

You have one 4 means switch, the only with four wires. It must have two more, 3 manner, switches with 3 wires each at the circuit.

Dan Harmon (writer) from Boise, Idaho on December 05, 2018:

@Bill:

You cannot do it the use of best 2 conductor cable (12-2), until you run two of the reasonably than a unmarried cable. As shown in the diagrams and as described, you must have 3 wires between switches, and that means 12-3.

Thank you Dan in your answer again.

This is an inexpensive metal ceiling mounted single bulb kind fixture this is enclosed with a spherical globe. It now has an LED light in it and I am not using the sunshine till it is fixed. The switch is disconnected.

Today I left a message for an electrician to call me that A pal really useful. I expect that he will name again on Monday.

The explanation why I give up all my DIY work is I hope that the electrician will alert our homeowners board if he agrees that the development used to be illegally miswired (with no grounds on switches and fixtures) when built. In 1977, all new building should have had all electrical fixtures, retailers, and switches grounded. I consider therefore that this whole apartment complex was once constructed "on the cheap" (for other reasons as well).

What I would like is for the homeowners affiliation to send letters out to the opposite condominium owners that they must have all in their devices electrically inspected and grounded (if essential). I don't believe that the homeowners association will act until they obtain a letter from the electrician with the corporate letterhead on it. Frankly, I doubt if they will act anyway even though they did receive this sort of letter. This makes me ponder whether I must move to the city about this if important.

Am I making a large to do about not anything? The way I see it, there are nearly four hundred condos and apartment gadgets in our complex that experience ungrounded light fixtures and lightweight switches. One could get electrocuted when she or he adjustments a lightbulb or touches the metal screws on a gentle switch duvet, if the fixture or the switch had a brief in it.

Dan Harmon (creator) from Boise, Idaho on August 04, 2017:

Probably not. I do not know what sort of fixture that is, but light fixtures are designed with getting rid of the warmth from a light bulb in mind. You've just closed off any chance of having air to it and it could overheat. If you really want to do that, I recommend an LED bulb because it doesn't put out any place close to the warmth of an incandescent bulb.

Of course, in the event you mean you've got removed the fixture and left an open box in the back of it, then yes it is tremendous to cover it with plastic.

Marshall on August 03, 2017:

Hi Dan, today I spread out my 8 foot prime ceiling light fixture with the three-way drawback. I found out that it's not grounded. After having stumbled on so many mild switches in my apartment that we're not grounded, I've come to the probable conclusion that the unique contractor never attached the grounds! I believe this ceiling light fixture had by no means been unfolded before

Long tale brief, Therefore I have ceased my own DIY work and can be calling an electrician tomorrow.

My question is this: as a result of this light fixture is so with reference to the toilet and since it could be tough for me to near it again up, I've put a plastic quilt over it to forestall bathroom humidity from shorting out this ungrounded fixture, until the electrician comes to mend it. IS THIS A PROPER THING TO DO?

Dan Harmon (author) from Boise, Idaho on July 30, 2017:

Okay. It sounds to me like your "switch two" accommodates the new wire from the panel and "switch one" accommodates the switch leg to the sunshine. This does not agree with your designation of a hot twine, or with observation 2 alternatively - I'm not somewhat figuring out what you're seeing for some explanation why.

At this level, I might disconnect all of the wires (non-ground wires) from the switches (labeling them somehow as to where they went, simply in case) and recheck simply what's hot with the breaker on. At the purpose the switch with the recent in it may be stressed out with the recent going to the common and both vacationers hooked up. Then check at the different switch; relying on whether or not the put in switch is up or down you must find two wires that become sizzling, one at a time. Those are the travelers and the one one left is the switch leg that is going to the average on that switch. I'm fairly confident that the "hot spur" is the new wire from the panel, which might imply that your "switch two" accommodates the new and "switch one" has the switch leg to the light, however I is also missing something.

Marshall on July 28, 2017:

Thank you on your answer once again Dan. I did some checking out. Here are my observations.

1...The mild is handiest on when both switch one (hallway by way of front door) and switch two (bed room) are in the "up" place.

2...But when switch one is up, and switch two is "down", the sunshine is off.

3...Also when switch one is down, and switch two is EITHER up or down, the light is off. This is why I recognized the hallway switch as "switch one", and the bed room switch as "switch two". BUT THE ODD THING IS THAT SWITCH TWO (Bedroom)IS PRACTICALLY RIGHT NEXT TO THE PANEL BOX. Switch one (hallway) is additional away from the panel field. Is the switch that is closest to the panel box on a three-way connection all the time known as " switch one"?

Here are some AC tester observations on the switch two cord connections. (Switch one was once closed up while most effective switch two was once unfolded). But first, a few notes:

NOTE: switch one is a 3 way switch with the hot hooked up to the average terminal, and the non-missing traveler hooked up to probably the most vacationers.

NOTE 2: Switch two is an outdated one pole switch (that I will replace with a 3 pole switch) with a work of black electric tape at the hot twine, and no tape at the non-missing traveler.

1...When both switch one and switch two are up (mild on), Then both the recent cord and the NON-missing traveler on switch two are "hot".

2... when each switch one and switch two are down (light off), Then best the hotwire is sizzling, and the NON-missing traveler is "cold" = lifeless.

3... when switch one is up, and switch two is down (light off), again, only the recent is sizzling, and the NON-missing traveler is chilly/dead.

4...but if switch one is down, and switch two is up (mild off) THEN BOTH THE HOT WIRE AND THE NON-MISSING TRAVER ARE HOT.

5... The nonmissing traveler (on switch two) is going up the similar romex (2-rope)cable as the similar white neutral wire that I found disconnected from the opposite three neutral wires in this double gang (each switches are on double gangs) switch (which I believe is the lacking traveler)

6...but the scorching cord (on switch two) is a "hot spur" this is pigtailed with four different black sizzling wires. (But that you simply say is supposed to be DIRECTLY attached to the light, And NEVER spliced with more than one/plural different wires).

Therefore, I have a MISCONNECTION! Could I've in all probability misidentified switch one and switch two?

Marshall

Dan Harmon (author) from Boise, Idaho on July 28, 2017:

You're right - in a correctly stressed out set up both wires cannot be scorching. One shall be, however the different is going to the sunshine and thus cannot be scorching always or the sunshine could be on at all times. Sounds find it irresistible is seriously mixed up, perhaps with one of the most travelers going to the sunshine as a substitute of the opposite switch. You have some work ahead of you, to sort out just what wires are going where.

Marshall on July 23, 2017:

I've another query about my 3 method switches. Re: the black wires that connect with the "common" terminal on each switches, should only one, or must BOTH wires be "hot" WHEN DISCONNECTED from the "common" screw? A "hot" cord as I realize it, is a wire that is engergized EVEN WHEN DISCONNECTED, unless the breaker to that circuit is turned off.

What I'm getting at is if BOTH black wires that connect with the "common" screw on BOTH 3 way switches are "hot"(even when disconnected, that would mean power is coming from both the "power in" cable and from the light fixture, this is, POWER COMING FROM BOTH DIRECTIONS AT ONCE.

(Note: I've now not yet put in each switches partly because of this). Am I lacking one thing right here? Or is that this a deadly bad connection?

Remember, I mentioned that BOTH the original 3 method switches had been replaced with 1 approach switches for some mysterious reason why years ago. (And I do KNOW that it is intended to be a 3 method connection) And I ponder whether this may well be the reason why. Could some handyman no longer familiar with 3 approach wiring have put in 1 approach switches after experiencing issues?

Hope it all helps.

No, I didn't disable any printing. But the website hosting company, HubPages dot com may have determined that that's not something they want to see. Not sure - I've never attempted to print feedback and have not heard every other court cases about it. Could be one thing about the avatar footage?

Marshall on July 21, 2017:

Thank-you Dan on your 2d answer! I imagine it's going to turn out very helpful. I was able to print your article re: 3-way switches, however I can't print any of the comments (both all of them, or simply my own in addition to your solutions "selected"). Did you disable the printing of the feedback?

Dan Harmon (writer) from Boise, Idaho on July 21, 2017:

It is fine to splice Four hots at the side of a pigtail (your "spur") to a switch. But that pigtail must go to the "common" screw at the switch, now not a traveler. Traveler wires ONLY go to the other switch. I feel you've got the idea: use one black traveler (already in position) and the white twine that isn't included in with the other whites as neutrals as the other traveler after making sure the other end is where you suppose it is and that it isn't doing one thing else in between the packing containers. I'm assuming that the second switch has the switch leg going to the light, at the side of a impartial - if this is the case using the extra white as a traveler (after taping it black on each ends) is ok. Just don't splice any further wires to that traveler (or another traveler). No cord nut on a traveler must ever have greater than 2 wires in it, simply continuing the similar cord with out including any more to it.

All grounds must always be nutted in combination, together with pigtails to any switch, outlet or different instrument.

(A matter of terminology simplest, however a 3-WAY switch isn't a 2 or 3 POLE switch. Technically this is a double THROW switch, connecting one twine to one or two different wires, not most effective separately. It has two "on" positions, which a double POLE switch does not.)

Marshall on July 21, 2017:

Thank-you to your answer Dan, you requested:

" But are you sure that someone in the past hasn't used what used to be a traveler to power something else? An outlet or something?"

I don't believe so. Here is what I AM certain of...

1...I've WOODEN studs and PLASTIC boxes.

2...In the bedroom 2 gang switch box, one of the vital romex neutrals was disconnected from the other three romex neutrals, with a piece of electrical tape covering the naked finish.

3...In the hallway 2 gang switch box, two of the neutrals had white masking tape on them to mark them (I since changed with white electric tape). The different two neutrals didn't have any marker tape.

4...I KNOW that those two switches are a 3 pole connection, however BOTH switches as I discovered them were ONE pole switches for some reason why. WHY WOULD SOMEBODY REPLACE 3 POLE SWITCHES WITH ONE POLE SWITCHES? I since replaced the hallway one pole with a new 3 pole, and intend to do likewise in the bed room.

5...An inherited renter who said he used to be an electrician lived within the unit in 2000(I acquired the condo in 2000, and rented it out till 2014, after I moved in). He said he put in the monitor lighting fixtures in the lounge (other circuit) which was different from the lighting fixture that used to be installed after I lived in that unit prior to from 1985 to 1987. I believe he could have fiddled around with the 3 pole connection for some reason why. Anyway, that observe lighting fixtures "blew up" in 2013 when my sister was renting the unit from me, consistent with my sister (I now reside in the unit as owner-occupier).

6...Two outlets in the living room are a part of the similar circuit as all the bed room outlets. Is that bizarre?

7...One of the bedroom 2 gang box romexes is a 14-3, but it is used to chronic a switch managed outlet within the bed room, which is authentic development.

8...When I lived there earlier than, I had no electric issues of any kind. Since I moved within the unit in 2014, no longer handiest does the 3 pole connection now not paintings appropriate, however the 2 gang field in the lounge has a nasty on/off switch and/or dangerous dimmer switch that used to regulate the observe lighting fixtures that "blew up" (since replaced with a pull chain ceiling fan two years ago that has all the time worked high quality), I replaced ALL the shops (some had been unfastened), and I had the defectively designed" PFE stab-lok"(which I still have and would like to get examined, but the place? Certainly no longer UL!) panel field changed in 2015. I also attached the grounds within the 2 gang packing containers in the bathroom and the hallway (the bed room is next).

9...All 4 black hot wires are pigtailed in combination within the bed room 2 gang box, with black wire spurs attached to the switches. Is that kosher?

10...All four ground wires within the hallway 2 gang field are now hooked up in combination. But I firstly stumbled on them with one attached to only one different (occasions 2). All four ground wires in the bedroom 2 gang box are correctly connected in combination, however the swit;ches aren't grounded (which I intend to right kind in a while)

11...The one traveler that IS connected within the bedroom 2 gang field is a black spur that is hooked up to all 4 romex black wires (see #9). Therefore, if I hook up one of the most 4 romex neutrals to it, I can have to relabel it with black electric tape to indicate that it's now sizzling. But first, I have to do a continuity check to determine the opposite finish of that SAME cord at the other (hallway) 2 gang switch. For you have stated that a traveler wire MUST connect DIRECTLY from one 3 pole switch to the other 3 pole switch (but splicing broken connections in between OK). But I imagine you said that UNDER NO CIRCUMSTANCES, to connect traveler spurs INDIRECTLY to all four white neutrals, or black hots that are pigtailed in combination throughout the box, if I understand you appropriately.

Anyway, I am hoping this lets you assist me with my situation. I thank you very a lot for what you may have advised me so far.

Dan Harmon (writer) from Boise, Idaho on July 20, 2017:

I'm sorry, however I will be able to't resolution the query on 1977 code - it used to be sooner than my time.

If you will have 2 14-2 wires working between the switches, and have wooden studs (nearly indubitably) and plastic bins (almost definitely) then you'll be able to make it paintings with what you've. You must figure out which cable is which in each switch box after which colour each ends of one of the white wires. Make it any color however white or green. At this level you may have all the wires you need to make the 3 manner switches and the sunshine paintings. But are you certain that somebody up to now hasn't used what was a traveler to continual something else? An outlet or something?

Marshall on July 20, 2017:

I reside in a 1977 vintage apartment building in the US. My bed room entry mild is controlled by two 3 means switches which might be housed inside of two separate double gang gentle switch containers. The manner it's now, one switch must be left in the up place at all times, in order for the opposite switch to show the light on or off. But the 2 switches will have to be capable of work fully independently if every other. There is no 14-3 cable used for the three-way connection. There are best 14-2 cables to be had for this connection. Black wires are used for the common and one of the vital travelers on the 3 pole switches, but the other traveler is lacking. But I believe that it at the beginning had a white neutral spur attach from the opposite traveler terminal on each switch as much as the 4 impartial wires all spliced together in each double gang packing containers. I know this doesn't meet provide code, however did it meet the latest code back in 1977? My actual query is do I absolutely must have a brand new 14-3 twine added into the circuit to have a protected 3 pole switch connection?

Dan Harmon (author) from Boise, Idaho on March 22, 2017:

Hi Angela:

It feels like you will have an overly previous home and that may be a problem. If the wires are Romex (two or three insulated wires encased in an outer sheath) you'll want to substitute the field with an "old work" or "cut in" plastic box - that is not a hard factor to do and it is very inexpensive. If the wires aren't Romex, but outdated knob and tube, it's not something you truly want to deal with, so if you can't see that those wires are all enclosed together in an outer sheath, or every twine enters the field one by one, don't try it.

Outside of that, the only factor left is to give protection to those screws at the aspect - I'm not conscious about any switches to be had to day with screws at the again. One risk could be to use electrical tape and wrap all of the switch, going up the aspect, around the top and fully around, completing the circle several occasions, protecting the ones screws with a number of layers of tape. Many electricians will do this as a matter of course.

But if the screws are already touching, that is more than likely no longer an actual excellent solution, as motion over the years may wear a hole in the tape. Better could be to cut a work of rigid plastic (now not a piece of plastic bag), as thick as conceivable, and slide it along the switch, preserving the screws away from the wall of the field. Do either side of the switch. There may be insulating subject material available, similar to what a circuit board is constructed from, that can work as smartly and is moderately skinny.

Angela Schmitt on March 21, 2017:

We have a 3-way switch in our bathroom for the sunshine, fan, and night light. We decided to place in a brand new one as we re-did our toilet and wanted the colours to compare. The outdated switch had the screws on the again of it, however the new one has metal screws on the side and they touch the steel field. This reasons it to spark when he turns on the continual. What can we do? (Hopefully this made sense--I do know nothing about wiring.) Thanks!

Dan Harmon (creator) from Boise, Idaho on January 11, 2017:

You can not do this with three method switches. Consider that if they're both down, and the sunshine off, you would need to flip either one of them to the up place to show it on, defeating the aim of three method switches.

What you CAN do, even though, is ready them so that they have got to be either each up or both all the way down to be on - when they are reverse each and every different the sunshine is off. Wire them, take a look at it and spot what occurs. If it is not what you wish, either turn one over or reverse the traveler wires on just one in every of them.

[email protected] on January 01, 2017:

This isnt actually a remark more of a question . I believe I got had a few years back a coworker confirmed me a strategy to cord 3 manner switched so that you would always have the 2 three manner switches within the down position when off and the two within the up place when on. If he did do this which at the time appeared like he did , I want to know the way think it is not conceivable.Am I appropriate I just by no means had anyone even check out it. Your article was and thank for your entire insight and information.

Dan Harmon (author) from Boise, Idaho on November 10, 2016:

The very best you will be able to do is to twine the opening to the typical terminal of the switch relatively than the traveler terminals. If it is the continual coming within the outlet might be on all the time, if it is the mild the hole will go off and on.

But there may be some other drawback as well. Unless you'll absolutely guarantee that the white twine is a impartial (and it may not be) you will be wiring the opening in series with the light and it'll now not work correctly. If I'm working out it properly, that white twine is terminated at the switch: if that is the case it's NOT a impartial and what you are attempting to do won't work as you're wiring the hole and light-weight in collection. It is a danger this fashion and must now not be executed.

Unless there are additional wires than the 3 you mentioned, multi function cable, you can't make the outlet work. There should be an extra cable, with a white and a black twine in it, within the field to make the outlet paintings at all.

Rick on November 10, 2016:

Hi Dan,

I have mild switch at the wall of my stairs at the top (2nd level of area) and on the bottom (1st point of area). It operates as a two approach switch. Turn on going up, flip off once up or activate upstairs happening and stale as soon as down. Anyways... I put a duplex outlet on the reverse facet of the wall from the light switch at the bottom of the stairs and meant to power off of the sunshine switch. The mild switch has 3 wires and a floor connection. One red, one hot black, one white impartial (all stressed out from the back of switch) and ground cord to the box screw. I wired the duplex expecting it to paintings however have some problems. When I turn the light switch on, the ability on the duplex goes off. When I flip the light switch off the flexibility to the duplex is on. I Have switched wires around but still have no longer had success. I did notice alternatively that if I touch the light switch neutral to the ground screw all of it works like as I be expecting. Can you assist shed some light in this?

Dan Harmon (writer) from Boise, Idaho on March 27, 2016:

Piet, you will have to have a power line in that field, plus at least 3 wires going out; one to every light. It could be possible to place two of them on one 3 wire romex, regardless that, the usage of the black and crimson as switch legs (one for every gentle) and the impartial.

Does that answer your question?

piet on March 27, 2016:

Dan Harmon (creator) from Boise, Idaho on March 29, 2014:

Article 404.2(C) is what you might be looking for. "For switches control lighting loads supplied by a grounded general purpose branch circuit, the grounded circuit conductor for the controlled lighting circuit shall be provided at the switch location"

And thank you for the pat; 3 way switches really aren't that difficult, just a bit other than most people are used to pondering of for switches.

donald on March 29, 2014:

I was just looking to look if the Code referred to as for color explicit wires for the travelers and came about upon your web site. I'm satisfied to see that there are people available in the market that make the effort to describe the functioning of a 3-way circuit in comprehensible detail as you've gotten. Pat at the again. I've a question. What article requires there to be a neutral in each switch box? Haven't been in "The Book" for someday and it is sensible to me. However it will be benificial to be able to display a buyer they have to pay extra for a role! Thank you.

Dan Harmon (author) from Boise, Idaho on March 05, 2014:

You will want to install the new 4 method switch in between the 2 3 method switch. In between that means electrically, no longer essentially bodily. You will want a 12-3 from a 3 method, to the 4 approach and directly to the other 3 means.

Instructions and diagrams are available here:

Spencer on March 05, 2014:

I've a 3 method switch that is working accurately In my basement. I need to add some other switch, to make it a 4 way, in between the prevailing two switches. I've 12-3 run from switch to switch. The chronic to the lights comes out of switch one with 12-2. Is that conceivable with out taking drywall off?

Dan Harmon (author) from Boise, Idaho on March 02, 2014:

Doesn't sound as if your motion sensors are 3 way. Are you completely certain that they're? In addition, the outdated switches, if 3 manner, had 3 terminals on them, plus a floor, that every one had to have a cord. Two black wires is not sufficient - what different wires/colours are in the bins?

Jacob on March 02, 2014:

I've a 3 method in my corridor approach my 2 new motion sensors have the 3 purple black and ground however the outdated switches have 2 black wires I know witch one is the average but with only 3 wires how do I hook up the 4th wire

Dan Harmon (author) from Boise, Idaho on December 27, 2013:

It is nearly certain that at one or the other of the switches the common wire has been switched with a traveler. Check at the switch the place the power originates and check that first one and then other other traveler is powered when the switch is flipped. If no longer, one of the vital vacationers is interchanged with the power right here.

Then verify on the other switch that the switch can transfer continual, or now not, without reference to which traveler is hot, to the average wire. If no longer, probably the most wires is interchanged with the common going to the sunshine fixture.

From your description, the issue lies with the flexibility switch. That switch will have to at all times produce persistent at one of the crucial two vacationers.

Jerry Leviner on December 27, 2013:

My downside after wiring for a new light with two 3 method swithes is if each switches are down then the light is not going to come on at either switch. It loses chronic at the non chronic switch! What did I do unsuitable?

Dan Harmon (writer) from Boise, Idaho on June 26, 2013:

If you place each black fixture and ground wires to the black cord from the circuit breaker the most efficient thing that may occur is that it'll blow the breaker. More most probably, in residential construction, it will cause the entire metal of the fixture to become "hot" each time the sunshine is grew to become on. Touch both the sunshine and a floor supply such because the sink tap and you are going to be surprised.

So, it's absolutely NOT OK to place the bottom twine to the black wire. If the house does now not have floor wires, merely tuck the fixture ground again into the box. The primary purpose of the ground wire there may be to blow the breaker if the fixture is defective one way or the other and the black cord is touching the steel portions of the fixture somewhere within the fixture. As long because the fixture is in just right situation (presumably a brand new fixture is) there shall be no downside.

phillip on June 26, 2013:

I have a chum doing work in my bathroom which has outdated wiring coming from the circuit breaker. The new gentle fixture we are including has a ground twine. He stated that it would be OK to twist the bottom cord into the black twine. Is this correct;

Dan Harmon (writer) from Boise, Idaho on April 20, 2013:

Yes, that will work positive. See the thing on 4 means switches for wiring diagrams. Just keep adding extra Four manner switches to the diagram, all the time between the 2 3 approach switches. There will probably be 2 3 approach switches, one at every end of the row of switches. One 3 method may have the incoming chronic and the opposite could have the cable feeding the light itself.

14 guage twine is okay, as long as it is being fed from a 15 amp fuse. DO NOT use 14 gauge cord on a circuit with a 20 amp breaker.

Dan Harmon (creator) from Boise, Idaho on September 13, 2012:

What you might be missing is that there is no "on" or "off" with a 3 manner switch. When the toggle is up, the typical terminal is connected to one of the crucial vacationers, when the toggle is down the average terminal is hooked up to the other traveler. There is not any "off" position. One or the other of the traveler terminals is all the time attached to the common terminal.

The wiring diagrams principally just show other strategies of bodily operating the cables; in each case one not unusual is attached to the incoming continual and the opposite is attached to the light. Traveler terminals are at all times hooked up to a traveler terminal on the other switch - by no means to both the sunshine or the incoming chronic.

Robert on September 13, 2012:

I'm sorry, however these all four wiring digram appears to be like to me the similar. Those don't seem to be unbiased connection. If first switch is on 2d switch work corectly, if the primary switch is off the second one switch does not paintings. I'm no longer having a look solution like this.

Dan Harmon (creator) from Boise, Idaho on July 11, 2012:

Thank you for the praise. These switch may to start with seem advanced, but at the heart are if truth be told slightly simple. The absolute best thing about them is that they are at all times hooked up electrically the similar irrespective of the bodily realities of operating wire.

Dan Harmon (author) from Boise, Idaho on February 23, 2012:

If you might have three white wires to one aspect then they are all both neutral wires or grounds. Any hot put to the same aspect as both a impartial or floor will straight away blow the fuse or breaker.

With additional information I may be able to offer extra concrete advice. Is this previous (pre 1950s) knob and tube wiring? Are there cables in the box that include (or more) wires in each and every cable? Are there any wires within the field which can be spliced in combination? Should this be a switched outlet, with one half hot always and one half switched? Are the wires sufficiently old to have suffered a color exchange, at least to the purpose that black has become grey or grimy white?

So a long way I'm seeing a field with three neutrals and just one sizzling wire. I will't conceive of any utility the place this may be fantastic apart from in all probability knob and tube wiring, where there was once no cabling. All customary house wiring has at least a black and a white in each cable. Or is this as opposed to a area with the wires entering the box by means of a conduit (pipe)?

rewiring an outdated outlet-found 3 white wires to one facet of the hole 1 black to sizzling side-i can best think that 1 of the white wires will have to be a sizzling as smartly,?since the outlet wont paintings?thank you

Dan Harmon (writer) from Boise, Idaho on January 03, 2012:

@ stefan - should you spliced the white wire to the hot, it's then a scorching, no longer a neutral, and will have to be colored at each ends in order that no one will mistake it for an actual neutral. Black tape is fine for this function.

Understand that it's not the color that makes a impartial; it is where it in the end results in the breaker panel. Those wires or the electrons flowing in them have no idea what colour the insulation is. People do, regardless that, and this is the reason the NEC has decreed that each and every neutral be white - while you spliced that white cord to the black sizzling it's not a impartial and should no longer be white.

Interestingly, that rule is so vital that the NEC won't let you color a wire white. You might exchange the colour from white to anything (excluding green), however by no means from say, black, to white. The best exception is for #Four and larger wire, which is so large that the only use in most houses is from the road into your own home.

Stefan on January 03, 2012:

Thanks for diagram 4. No different book I checked out in Home Depot or online confirmed diagram 4. Once I hooked everything up, I color coded the impartial that was once spliced to "hot" with black tape. I'm hoping this was the correct motion, since the impartial spliced to sizzling acts like sizzling when the precise switching combo is performed. Did I do right by labeling the neutral "hot" in the second one switch field? Thanks.

First, grounds will have to NOT be separated. Any and all grounds in the similar box are at all times to be tied together (exceptions may also be made for special computer circuit grounds).

Let me see if I perceive what you are attempting to do. You have 4 three method switches and two lighting fixtures. Two switches are to run light(A) and two switches are to run light(B). Power is coming from the fuse panel into the field with the first switch, (call it 1A). The similar chronic will then move to switch (1B). From that time, the wiring is similar for each and every control circuit.

I am assuming right here that one gentle is to be stressed out as in diagram #3. The different gentle, with its personal two switches is also wired as in diagram #3. If that is the case, then the ability in cord (black), the ability in impartial (white) and the bottom (bare or inexperienced) should move to either one of the primary two switches, one for every light. Simply run a two rope between those two switches, splice onto the power in cable, and deal with each set of switches as independent.

Please let me know if this answers your question. If not, let me know either with every other remark right here or with an email (touch knowledge close to the highest correct, underneath my profile knowledge). These things are tough to answer with restricted data and with just the written phrase, but we will get it solved.

Do you have any tips for wiring 2 separate 3 approach switch setups (switch-switch-light) from the similar persistent supply? I've stressed out it and even separated the neutrals at the second switch but nonetheless can't get the power to switch off. Do I want to separate the grounds additionally?

Dan Harmon (writer) from Boise, Idaho on December 07, 2011:

It's in reality arduous to diagnose from a distance, but the chronic getting into the second one switch will all the time are available in (when the first switch has the primary chronic cable) on a traveler.

You must have two wires marked as vacationers and one as common (which will never go "hot" with out that second switch stressed out in). If the one marked "T" by no means goes hot, I would suspect that it is the not unusual, now not a traveler.

You can use a volt meter, or the non contact voltage detector to track the wires. Make positive the wires are capped and protected in the second one field and turn persistent on. Flipping the primary switch should come up with two wires that move scorching, then chilly when the switch is flipped - those are travelers at the second switch. From your description, that leaves two wires; hook considered one of them to either traveler and switch that traveler scorching; if the light works that twine is then it's the commonplace and the fourth cord will have to be simply capped with a twine nut.

However, it's imaginable that previous owners stressed out in a second switch that by no means worked correctly. If you employ wiring diagram #3 above, and handiest use two rope cord, the switches may work, but not correctly. Is that most likely what has happened?

We have an older house and had a 3 way switch between to attached fan/lights. Power comes into Switch #1 and if we use simplest Switch #1 to the fan/lighting they paintings. . . .however we try to add the Switch #2 back in. We had a twine marked because the "T - traveler" but we can not get the switch #2 to paintings again--we can not appear to get continual to it. There isn't the fashionable 3 cord used, it was once two separate double wires firstly used. Can you pass from the ability Switch #1 to Switch #2? Would we be running new 3 twine to the Switch #2 or are we able to attempt to get it to paintings back as it's?

Dan Harmon (writer) from Boise, Idaho on November 14, 2011:

It's in fact beautiful easy, is not it? All those wires and ceaselessly colours on a 3 means light switch glance confusing but once you realize what's actually happening it isn't so bad.

Glad you chanced on it useful, and thanks for the comment. It's all the time just right to hear that I've been able to lend a hand out.

rocco on November 14, 2011:

thank you so much,for the a couple of ways,i now have higher figuring out of the terminology and the wiring approach

Dan Harmon (author) from Boise, Idaho on September 11, 2011:

Good. It is indisputably tempting to avoid wasting effort and time by way of cutting corners, however this is not where. It's just too bad, now and in the future.

wade on September 11, 2011:

Thanks for the reaction, I should not have felt just right about doing it that means. But, he had run the cord and had his partitions up for his room addition. I believed I could possibly save him time from the setback. Again, Thanks, I see it is not definitely worth the possibility.

Dan Harmon (creator) from Boise, Idaho on September 09, 2011:

Yes, in additional tactics than one. Without a floor there's a potential surprise hazard. You will not be able to make use of the legally required floor screw at the switch. It is not prison to do what you might be proposing and any future issues (area burns down in all probability) that may traced to that wiring will lead to legal responsibility to whoever did it. In many states it's illegal to promote a area with recognized deficiencies like this with out notifying the buyer, whereupon the sale most likely would possibly not go through.

In quick, do not do it. As an electrician I wouldn't do it, and if ordered to via the boss would refuse. It just is not price it. These codes are in position for a very good explanation why and need to be adopted.

Good good fortune with your venture.

wade on September 07, 2011:

Im helping a chum with wiring 3 ways, he has already run 2 twine/with floor to the switches, am i requesting bother if we skip the ground? (use the bottom for a traveler)

Dan Harmon (author) from Boise, Idaho on September 07, 2011:

Thanks to the both of you for the comment; it helps to know that you to find the tips useful.

Great data. GBY

Dan Harmon (author) from Boise, Idaho on October 18, 2010:

You are completely correct in that it may be very frustrating. I once attempted to hassle shoot a chum's paintings and he had put in a 4 manner instead of a 3 way (which is imaginable and can paintings) but had it stressed out wrong. It regarded correct in the event you did not understand the 4th screw, but wouldn't work correctly. Almost 2 hours of tearing all of the switches and 4 little can lights aside before I spotted his error! Extremely frustrating!

dgicre from USA on October 18, 2010:

This is excellent! Very commonplace drawback and hooking 3/means switches up the flawed approach leads to a couple interesting and steadily irritating reviews.

Dan Harmon (creator) from Boise, Idaho on October 18, 2010:

Thank you for the compliment. Wiring a 3 way switch is simply sufficient other that many people have hassle with it. My hope is that the diagrams and explanations will make it understandable for people that have even a modicum of experience there.

At least you chanced on your problem; many finally end up hiring an electrician to to a Five minute activity!

Dallas W Thompson from Bakersfield, CA on October 18, 2010:

As a certified California Contractor, I thought I knew basic wiring. I purchased what I believed used to be a three-way switch. Imagine my frustration after checking my wiring thrice, I checked the three-way switch to determine it was a standard unmarried pole, on-off two-way switch... Great knowledge for individuals who perceive the idea that of wiring...
