Step 1: Turn off the power
Before you begin any electrical work, make sure to turn off the power to the switch. Locate your home’s electrical panel and find the circuit breaker that controls the switch you’ll be working on. Flip the switch to the “off” position and then test the switch with a voltage tester to ensure that there is no electrical current flowing through the wires.
Step 2: Remove the existing switch
Once you’ve verified that the power is off, remove the cover plate and screws from the existing switch with a screwdriver. Gently pull the switch out from the electrical box and disconnect the wires from the screws on the back of the switch. Depending on your switch, you may need to use pliers or a screwdriver to loosen the wires.
Step 3: Identify the wires
There are three wires that will be connected to the dimmer switch: a black “hot” wire, a white “neutral” wire, and a green or bare copper “ground” wire. Identify these wires in the electrical box by their color and location. The black wire is usually connected to the top screw, the white wire to the bottom screw, and the ground wire to a green screw or metal clip.
Step 4: Connect the wires to the dimmer switch
Connect the wires from the electrical box to the corresponding wires on the dimmer switch. Begin by wrapping the end of each wire clockwise around the appropriate screw terminal on the switch. Tighten the screw with a screwdriver to secure the wire in place.
The black wire from the electrical box should be connected to the black wire on the dimmer switch. The white wire from the electrical box should be connected to the white wire on the dimmer switch. The green or bare copper wire from the electrical box should be connected to the green screw or metal clip on the dimmer switch.
Step 5: Secure the wires
Use wire connectors to secure the wires together and prevent them from coming loose. Screw on the wire connectors clockwise until they are snug and tight.
Step 6: Attach the dimmer switch to the electrical box
Once the wires are securely connected, carefully tuck them back into the electrical box. Attach the dimmer switch to the box using the screws that came with the switch. Make sure the switch is level and flush against the wall.
Step 7: Test the switch
Turn the power back on at the electrical panel and test the dimmer switch to ensure that it is working properly. If the switch is not functioning correctly, turn off the power and double-check the wiring.
Step 8: Install the cover plate
Finally, install the cover plate over the switch and screw it in place. Turn on the lights and adjust the dimmer switch to your desired brightness level.
Congratulations, you’ve successfully installed a dimmer switch with 3 wires! Remember to always follow safety guidelines and turn off the power before working on any electrical components.
