Three-wire cable runs between the switches and 2-wire cable runs to the light. Either way , complete these five steps for way light switch wiring : Turn off the correct circuit at your electrical panel. Add an electrical box for the second three-way switch in the basement. Feed a length of 14-type NM cable (or 12-, if you’re connecting to 12-gauge wire ). The black (line) wire connects to the common terminal of the first 3-way switch. A 3-wire NM connects the traveler terminals of the first and second 3-way switch together.

Traveler wires are interchangeable on each switch. The common terminal of the second 3-way switch connects to the light fixture(s).

The white neutral wires are connected together in each switch box. Wiring diagram for a 3-way switch , one of the many wiring diagrams showing different methods of wiring a three way switch circuit. Peel back the sheathing and trim it square. With wire strippers, put single wires in the proper size groove in the handle (for No. gauge wire ). Twist the stripper or rotate it 3degrees, sliding the insulation off the wire as it breaks loose under the cutting blades. Way Switch Diagram TIPS continuous hot and light feed wire goes on black screw.

WATCH all videos below for easy steps. Two Red wires : These wires attach to the travelers which are the pair of wires attached to the two screws at one end of the regular 3-way-switch. One Black wire : Attach to the wire commonly found on the screw by itself on the regular 3-way switch , typically the Power or the Switch Leg leaving to the fixture(s).
