In reply to wiring diagrahm for 3 way switch by Kevin Thompson on April 10th, 2003 09:39 AM [Go to top of thread]

Each switch will likely have a grounding screw on the end of the switch, one screw on one side of the switch and two screws on the other side of the switch.

Typical is the following, though alternative methods are sometimes neccessary:

The power comes into box #1. The black (hot) is connected to the single screw on the side of switch #1.

Run two wires (called travelers), one from each of the two screws on the other side of switch #1. These two wires exit box #1 and go to box #2. Inside box #2 they connect to the two screws on the side of switch #2. It doesn't matter which of the two screws the wires are connected to, as long as the wires run from the two screws on switch #1 to the two screws on switch #2.

The final wire black (hot) wire connects from the single screw on the side of switch #2 and runs to the light fixture. There it connects to the black wire on the fixture.

Ground wires are usually bare copper, or copper with green insulation.

Neutrals are white.

Hots are traditionally black, but can be red. If you use a white/black combo as the travelers between the two switches, you are using a white wire as a hot wire. Use a black permanant marker and color the last coulpe of inches of white wire insulation black to show that the white wire is indeed being used as a hot.

If none of this makes sense...stay away.
