What color wires go on a 3-way switch?
There is no standard for wire colors on 3-way switch travelers. The colors will vary depending on whether NM cable or conduit was used. With NM cable, the wire colors for travelers will be black and red using 3-wire cable. With conduit, the wire colors for travelers could be any color.
At what terminal of 3-way switch we connect wire going to wire going to the load?
The common terminal is the “bridge” between the power supply and the load (typically a light fixture). With this in mind, the wire that attaches to the common terminal is either (1) a hot wire from the main board or (2) leads to the load (fixture).
Where does the red wire go on a 3 way switch?
