Certainly! Wiring a 3-way electrical switch allows you to control a light from two locations. Here’s a step-by-step guide:

1. Turn off the power: Locate the breaker that controls your lights or the existing switch and turn it off.
2. 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.
3. 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.
4. 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! 😊
