- The black (hot) wire connects to the brass or black screw.
- The white (neutral) wire connects to the silver screw.
- The ground wire (bare or green) connects to the green screw.
- Tighten the screws securely.
- Push the switch back into the electrical box and screw it into place.
4. Test the Installation
- Turn the power back on at the breaker.
