How to Rewire Your Home’s Electrical System Yourself

Rewiring the electrical system in your home can seem like a daunting task, but with proper planning and by following safety precautions, it is possible for a homeowner to rewire their home successfully. Here is a comprehensive guide on how I rewired my home's electrical system myself.

Assessing the Current Electrical System

Before beginning any rewiring project, it's important to thoroughly assess the current electrical system in your home. Here are some key steps I took:

Inspecting the Electrical Panel

The electrical panel, or breaker box, is the central component that connects the whole electrical system in your home. I checked the following:

Checking all Outlets and Fixtures

I tested every outlet and light fixture in my home to take notes on:

Planning the Rewiring Project

After thoroughly assessing my electrical system, I developed a detailed rewiring plan. Key steps in my planning process included:

Choosing a New Panel Size

Based on my inspection, I determined my current 100 amp main service panel needed upgrading to 200 amps to handle added circuits.

Mapping New Circuits

I mapped out new 15 and 20 amp branch circuits to evenly distribute the electrical load throughout my home. Important factors included:

Selecting Updated Outlets and Fixtures

I opted to replace all outlets with grounded 3-prong outlets for safety. I also chose LED light fixtures for increased efficiency.

Calculating Needed Wiring and Materials

I measured all circuit runs and added up the total footage of 12/2 and 14/2 NM electrical wire I would need. I also made a list of all required materials such as junction boxes.

Developing a Step-by-Step Rewiring Plan

I wrote out a step-by-step plan to systematically rewire my home, starting with replacing the service panel, then rewiring each circuit one-by-one.

Safely Rewiring the Electrical System

With proper planning complete, I was ready to rewire my home's electrical system. I followed important safety measures:

Turning Off Power and Checking It Was Off

I turned off the main breaker and then checked outlets with a tester to confirm power was shut off. I also put a warning sign on the electrical panel informing others not to restore power.

Working on One Circuit at a Time

I disconnected and replaced each circuit individually, from the panel to all outlets and fixtures. This prevented any mix-ups in the wiring.

Using Safe Electrical Procedures and Gear

I followed proper protocols for making connections and insulating wires. I also wore rubber-soled shoes, insulated gloves, and safety goggles for protection.

Having Inspections Done

I had my work inspected by the local building department after replacing the service panel, and again when the whole rewiring job was complete.

Results After Rewiring Electrical System Myself

Completing this major DIY rewiring project myself saved thousands of dollars in electrician fees. More importantly, I gained updated electrical:

While rewiring your home is complex, the savings and benefits are tremendous. With good planning, safety diligence, and inspections, homeowners can tackle rewiring projects successfully. This project improved my electrical system for the next several decades.
