How do you properly wire a dimmer light switch?

To properly wire a dimmer light switch, first turn off the power to the circuit. Remove the old switch and connect the dimmer switch's wires to the corresponding wires in the electrical box. Typically, you'll connect the black wire to the hot wire, the green wire to the ground wire, and the red or white wire to the neutral wire. Secure the connections with wire nuts and then carefully tuck the wires back into the box before attaching the dimmer switch to the box. Finally, turn the power back on and test the dimmer switch to ensure it is working correctly.
