Iâ ve decided to put this faq together to help those with questions about installing ge 3 way switches. If the white is correctly used for neutral the connected switching wires are red and black.

How to identify the common wire on a 3 way switch. Shut power off at the breaker for the circuit. Turn power back on at the breaker. Pick a switch and disconnect it. If the hot wire remains hot i have found the most upstream line wire. Probe the wires at the disconnected switch. The white neutral is often referred to as common but the colored wires are both used as hot wires alternately as the possible switch positions are made.
In a 3 way configuration the line wire should be connected to the common terminal of the brilliant control. The switch wiring for three ways is normally red black and white. The hot wire from the breaker usually black neutral. If i find a hot wire then go flip a switch elsewhere in the circuit and probe again. The brilliant control can automatically detect which wire is line and which is load so they are interchangeable when installing in a single pole configuration. It is usually a black wire.
