Step 1: Turn Off Power
Turn off power at the circuit breaker for the room or outlet where you’ll be installing the dimmer switch. Flip the existing switch on and off to confirm the power is out.
Step 2: Remove Switchplate
Remove existing switchplate cover with a screwdriver. Then unscrew and disconnect the standard switchplate. Remove wires, one at a time, paying attention to the existing wire placement. If desired, snap a picture of the setup before disconnecting so you can easily remember which wire goes where.
Step 3: Connect Dimmer Switch
Connect the dimmer switch to the outlet, one wire at a time. The green and bare copper wires from the switchplate attach to the ground wires in the outlet. The black wires from the switchplate connect to the black wires in the outlet. Cap off any remaining wires with wire caps. Editor’s Tip: Carefully read the manufacturer’s instructions for your switch before installing. You may need to connect the wires differently.
Step 4: Attach Switchplate
Once the wires are all connected or capped, push them back into the wall. Screw the dimmer switchplate into place with a screwdriver. Restore power at circuit breaker.
