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.
  4. Connect the new device using the manufacturer's instructions, secure all grounds, and tuck wires neatly into the box.
  5. Restore power, test operation, and stop immediately if you see heat, arcing, smoke, or unexplained voltage.
Safety note

Stop and call a licensed professional when the work involves gas, service-panel wiring, structural changes, active leaks inside walls, mold, asbestos, or anything outside your comfort level.
