Rewiring your home can seem like a daunting task, but with proper planning and precautions, it is possible for a homeowner to successfully rewire their house without hiring a professional electrician. As with any major electrical project, safety should always be the top priority. Performing your own electrical work does come with risks if not done correctly. However, with adequate research, preparation, and attention to safety, rewiring a home without professional help can be accomplished.

Develop an Electrical Plan

A thoughtful electrical plan is key to a successful wiring project. Consider these factors in your plan:

Purchase All Needed Electrical Supplies

Step-by-Step Process for Rewiring

Follow these steps to systematically rewire your home room by room:

1. Turn Off Power

Shut off the main breaker. Verify power is off with a voltage tester. Turn off supplemental breakers as well.

2. Remove Old Wiring

Carefully extract existing wires from walls and conduits. Label each wire's circuit location as you disconnect it.

3. Install New Wiring Pathways

Run new conduit and cables. Secure wires properly, leaving excess length for connections. Use staples for vertical runs in open walls.

4. Replace the Service Panel

Install the new main service panel if upsizing your service. Then re-mount existing circuit breakers.

5. Connect Circuits Room by Room

Follow your circuit plan room by room. Connect wires to breakers securely. Group similar rooms like kitchen and laundry onto shared circuits.

6. Mount New Receptacles and Switches

Install matching new outlets, switches, and cover plates room by room. Follow NEC mounting height requirements.

7. Inspect and Test Circuits

Inspect all connections. Turn on power and carefully test each circuit using a project plan checklist.

8. Finish and Call for Inspection

Conceal new circuits neatly in walls. Caulk exterior conduit penetrations. Call your permit office to have an electrical inspector approve the completed system.

By systematically planning the project, purchasing materials ahead of time, safely disconnecting old wiring, and methodically connecting the new wiring room-by-room, you can successfully rewire your home without the need to hire an electrician. Pay strict attention to safety, research local codes thoroughly, and be honest with yourself about your electrical abilities before beginning such a major do-it-yourself project. With preparation and care, upgrading your home's wiring is a project an ambitious DIYer can tackle.
