How to Replace a Stair Light Switch with a Dimmer · Step 4 of 6
In this video
Begin by connecting the bare copper or green ground wire from the electrical box to the green ground screw on the dimmer switch. Tighten securely. Next, identify the 'line' (hot) wire and the 'load' wire from your wall box. In a single-pole configuration, one black wire typically brings power in (line), and the other black wire goes to the light fixture (load). Connect the line wire to the black screw terminal on the dimmer (labeled 'BK' for Hot/Phase). Connect the load wire to the red or yellow terminal on the dimmer (labeled 'YL' or 'RD', ensuring the 'REMOVE THIS LABEL' warning is followed for single-pole if applicable). Make sure all connections are tight and secure. The video demonstrates stripping back a small amount of insulation from the black wire to connect to the dimmer's screw terminal, wrapping the wire around the screw in a clockwise direction before tightening.
