How Do You Wire A Three-Way Lighting Circuit?
A three-way lightling circuit makes it possible to control lights from two different three-way wall switches. A three-way switch has two different terminals that receive electricity from the power source and one delivery terminal where the electricity travels to the light fixture. If the lights are on, both switches receive from the same terminal. If the lights are off at one of the switches, the switching mechanism makes contact with a different receiving terminal, and the circuit is broken. Despite which switch is used, the two switches will become connected to the same receiving terminal. Run 12-3 non-metallic sheathed cable with ground wire between the two switch boxes and 12-2 non-metallic sheathed cable with ground wire from the power source to one of the switch boxes. Run a second piece of 12-2 cable from the second switch box to the light fixture. Connect the red wire in the 12-3 cable to one of the two parallel screws on the three-way switches, and attach the black wires to th
