How to wire a 3-way electrical switch
Certainly! Wiring a 3-way electrical switch allows you to control a light from two locations. Here’s a step-by-step guide:
- Turn off the power: Locate the breaker that controls your lights or the existing switch and turn it off.
- Run cables:
- From your power supply to the first switch location, run a 14-2 NM-B cable (white, black, bare copper).
- From the first switch to the second switch, run a 14-3 NM-B cable (white, black, red, bare copper).
- From the second switch to the light fixture, run another 14-2 NM-B cable.
- Wire connections:
- Connect the power source to the first switch.
- Use the traveler wires to connect the first switch to the second one.
- Finally, connect the second switch to the light fixture.
- Test the switches: No matter which switch you flip, the light should respond.
Remember to follow safety precautions and consider hiring a professional if you’re unsure. Good luck with your wiring project! 😊
