Methods to Wire A 3-Way Decora Rocker Switch

Decora is the lighting device brand line manufactured and distributed by Leviton Manufacturing. Differing from a normal toggle switch by the shape and magnificence, the Decora switch is more modern and fewer obtrusive when installed within the wall. The three-way Decora rocker switch operates a light fixture from two different locations, providing you with a convenient way of turning on the lights. For a three-way circuit to operate correctly, you should have two three-way switches installed on opposite ends of the circuit. The most common option to wire a 3-way Decora rocker switch begins with the facility supply located inside the primary switch box on the circuit.

Things You may Need
Phillips or slotted screwdriver
Wire connectors
2 Three-way Decora rocker switches
2 Single gang rocker switch plate covers

Turn off the circuit breaker inside the principle service panel that gives electricity to the three-way switch circuit.

Look inside the first three-way switch box on the circuit and identify the 2 sets of cables. The primary set of cables includes a black, white and bare copper wire. The second set of cables includes a black, white, red and bare copper wire.

Connect the white wire from the primary set of cables to the white wire from the second set of cables by twisting a wire connector onto both wires. Repeat the connection for the bare copper wire from the first set of cables and the bare copper wire from the second set of cables. Push both sets to the back of the three-way switch box.

Wrap the black wire from the first set of cables across the common screw on the three-way Decora rocker switch. The screw might be labeled as “COM” on the back of the three-way switch.

Wrap the black wire from the second set of cables across the screw on the left side of the switch. Wrap the red wire from the second set of cables around the remaining screw on the appropriate side of the three-way Decora rocker switch.

Attach the rocker switch to the three-way switch box at the top and the bottom of the switch and canopy with a single gang rocker switch plate cover.

Look inside the second three-way switch box and identify the wires inside. This cable set includes a black, red, bare copper and white wire wrapped in black electrical tape.
