Step-by-Step Instructions for Installing Multi-Way SwitchLinc Dimmers
When replacing a three-way mechanical switch, each switch will have three wires connected to it from the
wall box. Four-way or greater circuits will have four wires connected to the switches in the center of the
circuit. For this tutorial, we will follow the most commonly used wire colors for homes in North America.
1. Find the LINE wire. Your first task is to find out which
switch junction box is the one where the electricity comes
into the circuit. This box will contain the LINE wire
(sometimes called HOT).
a. Turn off the electricity at the circuit breaker panel.
b. Pull all the switches in the multi-way circuit out of their
junction boxes. Each switch should have three wires
connected to it. If the circuit is a four-way or greater,
some of the switches will have four wires.
c. Disconnect the wires from the old switches. If the wires cannot be detached by unscrewing them,
cut the wires where they enter the switch, then strip ½ inch of insulation off the ends.
d. Making sure that none of the wires are touching anything and that no one is around the wall
boxes, turn the electricity back on.
e. Using a voltmeter or voltage sensor, individually test each wire for voltage. When you measure
120 Volts AC, that wire is the LINE wire. LINE wires are usually black.
f. The other two wires, usually black and red, are the TRAVELERS and go to the next junction box.
TRAVELER wires are usually in the same cable sheath.
g. Turn off the electricity to resume installing the new SwitchLinc Dimmers.
2. Connect the SwitchLinc Secondary’s LINE Wire. The
SwitchLinc Dimmer that will be the Secondary goes in the
junction box where you found the LINE wire. Connect the
black LINE wire that you found, the black TRAVELER, and
the Black LINE wire on SwitchLinc Dimmer all together with a
single wire nut.
