How to Rewire Your Home Without An Electrician (And Save Thousands)

Introduction

Rewiring a home can seem like a daunting task, but with proper planning and safety precautions, it's possible for a homeowner to complete some rewiring projects without hiring an electrician. I've rewired parts of my own home, saving thousands of dollars in the process. Here's my guide on how to safely rewire your home as a DIY project.

Reasons for Rewiring

There are several reasons you may need or want to rewire parts of your home:

Upgrading to a Higher Amp Circuit

• Older homes often have 60 amp or 100 amp electrical panels.
• Upgrading to a 200 amp panel provides more power for running multiple appliances.
• This requires running new wire from the electrical panel through the walls.

Replacing Outdated Wiring

• Knob and tube wiring found in older homes is inefficient and potentially unsafe.
• Replacing with modern wiring like Romex allows for grounding and higher capacity.

Adding New Circuits and Outlets

• Additional outlets, lighting circuits, or high-power appliances may require new wiring.
• Running new circuitry provides capacity for additions and upgrades.

Safety First

• Working with electrical wiring can be extremely dangerous.
• Risk of electrocution and fire means safety should be your top priority.
• Turn off power at the main panel and verify it's off before working.
• Wear rubber-soled shoes and insulated gloves for protection.
• Inspect all existing wiring for damage before connecting to it.
• Have an electrician install the new breaker panel if needed.

Step-by-Step Guide

Here is an overview of the major steps involved:

1. Turn Off Power and Inspect

• Shut off power at the main breaker panel.
• Verify it's off by testing outlets with a multimeter or plug-in tester.
• Inspect existing wiring for damage and replace as needed.

2. Plan New Circuits and Wire Routing

• Decide which new circuits you need and map routing through walls/ceilings.
• Choose appropriate wire size based on circuit amperage needs.
• Have construction materials like conduit and boxes on hand.

3. Mount New Breaker Panel (if applicable)

• Upgrade electrical panel if needed before wiring new circuits.
• Hire an electrician to install new breaker panel if uncomfortable doing it yourself.

4. Run New Wires

• Fish wires through walls and ceilings along planned routing.
• Use junction boxes to join new wires to existing.
• Leave excess wire at endpoints for connections.

5. Connect Wires and Outlets

• Carefully connect wires to new outlets, switches and appliances.
• Securely fasten all connections and install covers.
• Label all new circuits clearly in the breaker panel.

6. Inspect and Restore Power

• Verify all connections are tight and insulated properly
• Have an electrician inspect if unsure
• Restore power and test each new circuit for proper function

Cost Savings

By taking the time to rewire parts of your home yourself, you can save thousands of dollars in electrician fees. Expect to spend about:

• $100-200 on wire and supplies
• $100-300 per new circuit depending on home layout
• $1000+ for upgrading the main panel

While not simple, with proper safety and planning, rewiring a home is very doable. Follow my guide to take on this money-saving project yourself! Let me know if you have any other questions.
