In a typical household, 3-way switches are used to control lights from two different locations. This setup allows you to turn the lights on or off from either switch, providing convenience and flexibility. One common wiring configuration is where the power source is at the light fixture and the switches are connected to the fixture. This is known as wiring a 3-way switch with power to the light.
When wiring a 3-way switch with power to the light, the hot wire from the power source connects to the common terminal on the light fixture. The two traveler wires then connect to the two brass terminals on the 3-way switches. This configuration allows for the switches to control the flow of electricity to the light fixture.
Wiring Diagram 3 Way Switch Power To Light
First, you will need to turn off the power to the circuit at the breaker box. Next, run a 2-wire cable from the power source to the light fixture. Connect the hot wire to the common terminal on the light fixture. Then, run two 3-wire cables from the light fixture to the two 3-way switches. Connect the traveler wires to the brass terminals on the switches.
At the first switch, connect the black wire from the 3-wire cable to the common terminal. Connect the red and white wires to the traveler terminals. At the second switch, connect the black wire from the other 3-wire cable to the common terminal. Connect the red and white wires to the traveler terminals. Finally, connect the ground wires from all cables and the light fixture together and to the switches.
Once all the connections are made, turn the power back on and test the switches. You should now be able to control the light fixture from both switches. If the light does not turn on, double-check your connections and make sure everything is properly wired. With the power source at the light fixture, wiring a 3-way switch with power to the light is a common and convenient setup for controlling lights in your home.
With this wiring diagram, you can easily install a 3-way switch with power to the light in your home. Remember to always turn off the power before working on any electrical projects and consult a professional if you are unsure about any wiring connections. Enjoy the convenience of controlling your lights from multiple locations with this setup.
