What wire is needed for a double 3-way switch on fan/light


My house is 60+ years old, with original cloth wrapped 2-wire 12 ga wires throughout the house, and an updated 200A breaker box. I wish to replace a 3-way switch setup on a ceiling fan/light with a double 3-way switch setup - a 3-way on the light and a 3-way on the fan. I am looking at using two Leviton 5640 in the existing single-gang spots, while replacing the old boxes with old work.

I planned on wiring it up based on some homeowner's how-to books, like this diagram shows. My question is what wire should I use to replace the existing 3-way setup, while adding for the double switches? I've wired a fan/light on a double switch before, using 12/3 with a ground, but I didn't know what wire I should need for the double 3-way setup.

From best I can tell, I need a hot and ground going to the first switch, 4 feeder wires going to second switch, and a 2 hots and a ground coming from second switch to...

Ceiling fan light 3 way wiring problem

I'm trying to wire two 3-way switches to the light fixture on a ceiling fan. One switch is a Cooper over/under Duplex switch with the top being a single pole switch that controls the fan and a 3-way switch on the bottom for the light. The other side of the room has your standard 3 way toggle switch. Power is coming into the duplex switch side then to the fan/light and on to the 3 way toggle switch side. No problem with the fan switch. Below is how I wired the light. I can turn the light on and off at the right side switch (toggle) and then and only then can I turn off the light at the duplex switch (bottom 3 way). When I turn the light off at the right side switch (toggle), I cannot turn it on at the duplex. How can I rectify this situation without going from switch to switch to light? I wired the 3 way switch on the Duplex side the same as this attached diagram. Black wire from the right side 3...

Wiring a three way light switch

Wiring of 3-way light switches is certainly more complicated than that of the more common single-pole switch, but you can figure it out if you follow our either of our 3-way switch wiring diagram. With a pair of 3-way switches, either switch can make or break the connection that completes the circuit to the light. The whole wiring a light switch project can be completed in a few hours if you don’t have to do any drywall removal and repair. Keep reading the 3 way switch wiring diagram to learn light switch wiring.


To add the switch, you’ll use one of two wiring a light switch diagrams, depending on whether the power comes to your light switch first (the most common situation) or to the light fixture first. Either way, complete these five steps for 3 way light switch wiring:

Turn off the correct circuit at your electrical panel. Add an electrical box for the second three-way switch in the basement. It’s likely...

Sing pole switch is a switch that you ordinary use for lights in your living room, it goes on and off.

while the 2way switch are the light switches in the stairs. you can switch on the light when your down and when you reach the top you can switch it off. or the other way arround. you can switch the light on or off. in sort a 2way switch can turn on or off a light bulb in 2different locations.
to do a setup for 2way switch is to have 2pcs of 2-way switch. connection is also labled at the back of the switch.

there is also a 3-way switch for 3-5 locations. for 3 location switches you need 2pcs 2-way switch an a 3way switch. the connection goes like this; power source = 2way switch = 3way switch = 2way switch = light bulb.

for 4 locations, it goes; power source = 2way switch = 3way switch = 3way switch = 2way switch = light bulb.

for 5 locations it goes power source = 2way switch = 3way switch = 3way switch = 3way switch = 2way switch = light...

I have a house (Georgia, USA) and some kitchen renovations have revealed some prior electrical work and I am trying to figure it out. Originally, there was a ceiling box in the kitchen with a fan/light fixture controlled by a pair of 3-way switches. One 3-way switch was located at the kitchen entrance to the garage and the other switch was located in a 2-gang box that it shared with a 2-way switch for a ceiling light in the dining area. The fan and light did not have separate switches.

At some point in the past, an exterior flood light was added to the house and the 3-way switch in the 2-gang box was replaced with a duplex switch. One switch controls the light fixture and the other controls the exterior flood light. The 3-way switch at the garage entrance was abandoned and covered with a cover plate. And by abandoned, I mean the 'electrician' bent back the tabs on the switch and shoved the entire switch into the...

Connect ground wires.

Provide as shorter lengths (8 inches/20.5 cm) of bare or green insulated wire to this wire-nutted group to allow connection to green ground terminal screws on each device in the box (switches, outlets, fixtures, etc.) - one length of insulated wire per ground terminal screw. If the switch or junction box is metal, it too

must be securely grounded

with a green ground screw or approved grounding clip. This must be done at each and every box that a cable enters and at each device that provides a termination point for ground.

It is highly recommended that you complete these ground connections first, and then gently fold them into the rear of the box - out of the way - leaving only the shorter ground leads out for easy connection to devices. No ground connection is made to plastic, fiber or another non-conductive...

1) First lesson to be learned whenever doing electrical work is to either take a picture or document wire colors prior to disassembling, unless you have a photographic memory:)

2) Unfortunately, ceiling fans are one of the most difficult electrical items in the home to repair. For whatever reason, the manufacturers never provide a schematic wiring diagram and replacement parts are often difficult and/or just impossible to locate. There are no standards when it comes to the types of switches and/or the wire colors that the fan manufacturers use. It's basically a crap shoot as to what they will use. I guess they want us to just purchase a new fan is my guess. Very frustrating for sure:)

3) About the only consistent element with the manufacturers is that the black wire should be the "L" or LINE side wire connection. You can confirm this using an AC voltmeter and see if it has 120 volts from the black to a ground wire.

4) As far as the other 3 wires for the 1,2,3...

We take for granted being able to turn a light on from the bottom or top of the stairs. But a wall switch that allows a device or outlet to be turned on and off from two different locations is not a standard switch. It is called a 3-way switch. (Another variation, a 4-way switch is used when you need to control a fixture from three locations.)

Identifying a 3-Way Switch

The 3-way switch is always used in a pair.

The toggle lever on a 3-way switch has no ON or OFF markings, because either up or down lever positions may turn the light fixture on or off, depending on the sequence in which the switches are used.

Inspected side-by-side with a standard double-pole wall switch, you will notice that the body of a three-way switch has three terminal screws: two bronze or copper colored screws (called TRAVELERS) and a third screw that is darker in color. This screw is known as the COMMON, and it may be labeled as such. The arrangement of these screws varies...

Someone enters the same room near the switch at the right of the graphic. He or she flips that switch. Now there is again a pathway for the electricity. This time it flows over the second of the two wires running between the switches.

When you encounter what was supposed to be a three-way circuit, and you can turn it "on" at one of the switches, but not at the other switch, unless the first switch is already "on," the problem is usually that one of the wires going into the switch is on a terminal for one of the two wires going out of the switch.

Not all three-way switches are the same, either. All of them have two screws on one side of the switch and one screw on the other side. But, the screws for the wires running between the switches may be on the same side of the switch, or they may be on opposite sides of the switch at the same end of the switch. You cannot make assumptions. It is not uncommon to find that one switch in a three-way circuit uses one arrangement,...

2 way switching means having two or more switches in different locations to control one lamp. They are wired so that operation of either switch will control the light. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.

Here we have a two way switching system that utilises two single gang two-way switches and a three wire control, shown in the new harmonised cable colours. It is possible to achieve a similar result using a two wire control which, although it saves on cable, is not recommended. This is the preferred approach.

Here we a have a schematic (Fig 1) which makes it easy to visualise how this circuit works. In this state the lamp is off, changing the position of either switch will switch the live to the lamp turning it on. If you now change the position of the other switch the circuit is broken once again.

First things first:

Always turn off power at the breaker before starting any electrical work. Turning off the switch won't do it. You can still have line voltage at the fixture.

Always adhere to local codes.

If you are in any way unsure of what you are doing, hire an electrician.

OK. If you have only a 3-conductor-plus-ground drop from the fan to the switch for both fan and light you do not have a neutral in the box. 12/3 or 14/3 will give you one line wire and two load wires. Line will probably be black (but not always), red will be one load and white the other (white should be marked to indicate it is not a neutral). At that point you are out of wires - no neutral. This is the most common way fan/light drops are wired.

You can automate the light and maintain local control of the fan and light pretty easily using a simple Zwave controller in the wall and a Aeotec Micro Switch in the fixture. You can wire the pull chain to the dry-contact inputs on the...

1. Open the switch housing of the fan. This is usually achieved either by removing two screws on the bottom cap of the switch housing, or three screws on the side. Remove the pullchain assembly by unscrewing the brass finial on the outside of the switch housing.

2. Make careful note of which wires attach where to the pullchain. The chain itself will be marked L-1-2-3 or A-B-C-D or similar, the wires will customarily be of different colors, but if not, mark both the wires and pullchain if necessary. MAKE CAREFUL NOTE OF WHICH WIRES ATTACH WHERE. Every fan is different and if you do not make note there will likely be a complicated guessing game. I cannot stress this step enough. Make careful note of which wires attach where to the pullchain. For example:

Black - L, Grey - 1, Brown - 2, Purple - 3.

Some fans may use only two or three wires, some may have a pullchain with two layers and five or more wires. Regardless, make careful note of which wires attach...

So, you want to add wiring a 3 way switch to your "handy-man tool belt", eh?

No problem, I can help you with that.

Three way switches have become very popular because it adds convenience and ease to lighting in large rooms, hallways and staircases. For more flexibility, add a four way switch.

I trust that you have already mastered how to wire a single pole light switch already so lets get right into it.

These switches are a bit more confusing and you may find yourself

getting a little frustrated... relax. Take your time, mark the wires properly and you will not only be successful, you will stay sane.

The first thing you will need to determine is where the power is coming from and where the switches are positioned.

I have a few examples below that should cover pretty much any situation.

Ok guys.
I need some help.
I have a great Room fan and light that are each on a 3 way circuit.
I have no idea how to wire this up right

The main wal box is 3 gang. Call it Wall Box A
It has fan, fan light and mud room light
A while back I swapped out mudroom for a GE switch and aux on a 3 way

Wall box B, 2 gang, contains the companion 3 way switches for both the fan and fan light

Wall box C is basically irrelevant to the discussion but I'm including it for the sake of diagraming ALL wiring related to Wall Box A. Wall box C, 1 gang, contains the GE Switch associated with the Aux switch in Wall Box A.

All I want is to wire up the Fan (not the fan light) on a Zwave fan controller. I have a GE Fan control switch and a GE Aux switch.

Here is a wiring diagram of the switches and all wiring coming into each wall box. It is color coded. Black/black, Blue/white(neutral), Magenta/Red, green is ground.
For sake of not...

1 it isn't 3 way switching it is called 2 way switching (there are only 2 ways for the electricity to go)

2 Part P of the building regulations (UK) state that only work certified by competent (i.e qualified electricians) meets the building regulations.

3 Without being conversant to BS7671 (The electrical installation regulations) (which is harmonised to the European regulations) You are risking Fire and or possibly death by indirect contact via improper fusing arrangements/ altering the earth fault loop impedance path.

What you want to do is possible you would need 2 * 2 way 230V switches, 1 * 2 way 230 volt relay (everything rated to the load of your circuit also taking into account the power factor) You do not need to know the state of the relay you could add a 5 V light sensor to the to change a variable 'lightOn' to either 1 or 0

230 Volts can kill and adapting mains voltage circuits with electronics is not for the untrained

Is Electricity Really Mysterious?

The scientist and the homeowner have two entirely different reasons for saying that electricity is mysterious.

They are probably talking about different things. The scientist is considering some basic principles of nature, which as yet have no deeper explanation. The average person might share such wonder. But when I hear a homeowner say that "electricity" mystifies them, they usually mean that they don't know how to deal with their...
