Turn Off Power and Remove Old Wiring

Safety first! Turn off the main breaker and all individual circuit breakers before touching any wires. Verify power is off by testing wires with a non-contact voltage tester.

Remove existing switches, outlets, lights, and other devices. Carefully label wires as you disconnect them so you can identify their circuit. Take pictures as you go along for reference.

Unhook and remove electrical panels. Finally, pull out old wires once everything is disconnected. Properly dispose of old wires and devices.

Install New Wiring and Devices

Follow your rewiring plan to install new wires, outlets, switches, lights, electrical panels, and other devices. Key tips:
