Assess the Existing Electrical System

Before beginning any rewiring project, it's crucial to understand what you're working with. Here's how I go about assessing the existing electrical system in a 120 year old home:

Look For Knob and Tube Wiring

Check the Electrical Panel

Identify Ungrounded Outlets

Locate Existing Wiring Pathways

Develop a Rewiring Plan

Once I understand the existing electrical system's condition, I can map out my plan:

Prioritize Required Upgrades

Choose a Realistic Scope

Plan Wiring Routes

Select Appropriate Materials

Safely Install New Wiring Yourself

With proper planning and extreme care, homeowners can safely rewire some circuits. Here are my tips for success:

Turn Off Power and Working Safely

Run New Circuits and Outlets

Update Lighting Fixtures

Inspect and Test Thoroughly

When to Call an Electrician

While many basic rewiring tasks are doable for a diligent DIYer, some activities are best left to electricians:

Proper rewiring is serious business. If a project scope exceeds my comfort level, I hire a licensed pro. Paying an expert to handle tricky parts that I can't legally or safely perform often makes sense. The last thing anyone wants is to burn a home down!
