Step 4 · Wire the New Dimmer Switch

Refer to the installation instructions that came with your new dimmer switch. Typically, you will connect the ground wire (green or bare copper) to the green screw on the dimmer. The two 'hot' wires (usually black) will connect to the two screw terminals on the dimmer switch that are not green. If the dimmer has wire leads instead of screw terminals, use wire nuts to connect the corresponding wires. Ensure all connections are secure and no bare wire is exposed beyond the terminal or wire nut.
