Wiring a 3-Way Switched Hallway Light
You'll have:
- 14/2 from panel: black (hot), white (neutral), bare (ground)
- 14/3 between switches: black, red, white, bare
At the first switch (power source):
- Connect the panel's black (hot) to the common terminal (usually black/dark screw)
- Connect the panel's white (neutral) directly to the light fixture's white
- Connect the panel's bare ground to the ground wire (14/3 bare) and switch's ground screw
- From the 14/3 cable: connect black and red to the two traveler terminals (brass screws)
At the second switch:
- The 14/3 black and red go to the two traveler terminals (brass screws)
- The 14/3 white connects to the common terminal (black/dark screw)
- The 14/3 bare ground connects to the ground screw
At the light fixture:
- The 14/3 white connects to the light's white (neutral)
- The switched hot comes from whichever traveler is active
Key point: The common terminal on each 3-way switch is the one that's electrically isolated from the travelers. It's typically a black or dark-colored screw, while travelers use brass screws.
Safety note: Always turn off power at the breaker and verify with a non-contact tester before working. If you're unsure about identifying the common terminal or don't have proper test equipment, hire a licensed electrician.
