With these diagrams below it will take the guess work out of wiring.

3 way wiring diagram power at switch. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. 3 way switch wiring diagram with power feed via light.

Then a 4 wire cable going between the two 3 way switches and then a 3 wire cable going from the switches to the load. In the diagram above splices are made and a three conductor cable is installed between all the switches. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together.

Each 3 way switch in these examples are controlling the power source to the same load. An example of three way switch wiring with the line and load in the same 4 square electrical box. 3 way switch wiring diagram.

Traveler wires are interchangeable. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. Take a closer look at a 3 way switch wiring diagram.

The black line wire connects to the common terminal of the first 3 way switch. Four way switch wiring diagram with the line and the load in the same switch box. This electrical wiring diagram shows power into light switch box 1 wire to light from switch box 1 and from switch box 1 to three way light switch box 2.

Pick the diagram that is most like the scenario you are in and see if you can wire your switch. Wiring a 3 way light switch. Typical 3 way switch wiring nm cable.

When wiring a 3 way switch circuit we will be using a 3 wire cable known as romex coming from the source such as the breaker box. Now discussing 3 way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires. The white wire needs to be re identified as a hot conductor because it is not being used as a neutral in this installation.

The travelers actually pass the electricity between the two 3 way switches as well as the 4 way switches shown in the 4 way switching wiring diagrams. Wiring diagram for a 3 way switch one of the many wiring diagrams showing different methods of wiring a three way switch circuit. In the above diagram the white wire must be re identified as a hot wire at each switch location.

The white wire between switches is not being used as a neutral. Regardless of what 3 way switch wiring diagram you re following you ll need to use a 3 wire cable to connect the two 3 way light switches. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire.

To illustrate the wiring of these 3 way switches switch boxes and fixture boxes are not shown but are obviously required for every application.
