3 Way Light Circuit Wiring Diagram A
This is also known as the conversion method since it is the easiest way to add a second light switch to an existing circuit.
3 way light circuit wiring diagram a. The fixture s hot wire connects. In the above diagram the white wire must be re identified as a hot wire at each switch location. Basic 3 way switch diagram how to wire 3 way light switch step by step. Three way switching 3 wires.
The white wire between switches is not being used as a neutral. This wire diagram shows the wiring for source power into the first three way switch then 3 wire cable to the next 3 way light switch and then on to the light or light fixtures. Three way switch lighting circuit diagrams. Now it is time.
The basic 3 way switch wiring diagram this is the most common and the easiest wiring diagram to follow of any of the wiring diagrams for a 3 way switch circuit. Here is our selection of three way light switch circuit diagrams. 3 way switch wiring diagram with line and load in the same switch box. An example of three way switch wiring with the line and load in the same 4 square electrical box.
This is where two switches control the same light or lights. The black and red wires between sw1 and sw2 are connected to the traveler terminals. Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit. Pick the diagram that is most like the scenario you are in and see if you can wire your switch.
Traveler wires are interchangeable on each switch. The first length of cable will be from the supply to the light itself. Three wire cable runs between the switches and 2 wire cable runs to the light. 3 way switch wire diagram power to light switch in this diagram the incoming hot wire attaches to the first switch s common dark colored terminal.
The two hot wires of three wire cable connect to a pair of brass colored traveler terminals on each switch. In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. Take a closer look at a 3 way switch wiring diagram. The first step in any electrical project is to make sure there is no power going to the circuit you plan to be working on.
Turn the power off at circuit breaker. This might seem intimidating but it does not have to be. The next length of twin earth cable will run from the light to the first two way switch. The black line wire connects to the common terminal of the first 3 way switch.
Let s break the wiring method down to steps. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together. Three wires between the two end switches probably using 3 core and earth cable. With these diagrams below it will take the guess work out of wiring.
Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block.
