Step-by-step written guide

1. Turn off power at the breaker and verify the circuit is dead with a tester before touching wires.
2. Photograph the existing wiring and label conductors so the replacement can match the original layout.
3. Remove the old device or fixture carefully, keeping wire nuts, mounting screws, and grounding hardware organized.

5. Restore power, test operation, and stop immediately if you see heat, arcing, smoke, or unexplained voltage.
