How To Rewire Your Home Without Dying – Lesser Known Historical Electrical Methods

Introduction

Rewiring a home can seem like a daunting task, but it doesn't have to be dangerous if you take the proper precautions and use safe, historical electrical methods. I have rewired my home multiple times over the years without electrocuting myself, and I will share my methods in this article so you can rewire your home safely as well.

Assess the Existing Electrical System

Before beginning any rewiring project, it's crucial to fully assess the existing electrical system. Here are some key steps:

Check the Electrical Panel

• Examine the electrical panel to see the type of wiring, age of the system, amperage capacity, and if there are any signs of damage or corrosion.

• Note if the panel uses screw-in fuses, cartridge fuses, or circuit breakers. This will determine how easy it is to upgrade.

• Verify that the panel is grounded properly through the grounding rod outside.

Look for Knob and Tube Wiring

• Inspect the attic, basement, and walls for signs of knob and tube wiring. This outdated wiring from the 1920s can be a fire hazard.

• If found, I recommend rewiring the entire home. Knob and tube wiring cannot handle modern electrical loads.

Check Voltage and Amperage

• Test outlets to verify proper 120 volt power. Use a multimeter or voltage tester.

• Calculate total amperage draw from large appliances to ensure the panel capacity meets your needs.

Choose a Rewiring Method

Once I've assessed the existing wiring, I determine the best rewiring method. Here are two lesser known historical approaches perfect for DIYers:

Original Cloth-Covered Wiring

• This vintage wiring from the 1880s-1920s features cloth or tar paper insulation covering copper wires.

• Less conductive than modern wire, but safe for smaller loads like lights and outlets when properly installed.

• Retains historical charm. Perfect for period restorations.

Armored Cable (AC) Wiring

• Developed in the 1920s, AC wire has an outer steel armor wrapping around rubber-insulated wires.

• More durable and heat-resistant than original wiring while maintaining a vintage look.

• Allows higher amperage capacity for larger electrical loads.

Safety Gear Needed

Rewiring a home comes with risks of shock and fire. To stay safe, I use the following gear:

• Insulated gloves - Protect from shocks when working with live wires.

• Safety goggles - Prevent injuries from sparks or wire clippings.

• Dust mask - Avoid breathing insulation particles or asbestos from old wire covering.

• Fire extinguisher - Have an extinguisher on hand in case of an electrical fire.

• Voltage tester - Verify power is off before working on wires.

• Warning signs - Post signs to indicate ongoing electrical work.

How to Rewire a Home Room by Room

Here is a step-by-step guide to rewire a home safely:

Turn Off Power

The first step is to turn off power at the main panel. Then, go around the home turning off all light switches and unplugging appliances to discharge any residual current in the wires. Verify power is off with a voltage tester.

Remove Old Wiring

Next, I take out the old wiring. I start by removing outlets, switch plates, and light fixtures. I pull the wires out from the walls and ceilings back to the electrical panel.

Be sure to wear a dust mask in case the insulation contains asbestos. Properly dispose of all old wiring.

Run New Wiring

Now the fun part - running the new wiring! I start at the panel and work outward room by room.

I staple the new wires to the centers of wall studs and joints of joists in the attic and basement. I leave some extra slack to prevent tension.

For original cloth wiring, I wrap connection points with electrical tape for safety. With armored cable, I use wire nuts to join wires.

Install Devices

After the wires are run, it's time to install the outlets, switches, and light fixtures. I match amperages and use mounting brackets suited for my wiring method.

I also make sure to connect the ground wires properly - safety first!

Turn Power Back On

Once everything is securely installed, I turn the main power back on and test each outlet, switch, and light to verify proper operation.

I also check for hot spots in the wiring that could indicate unsafe connections. If any issues arise, I troubleshoot and fix them before completing the rewiring project.

Maintaining Safety Throughout the Process

Rewiring a house takes time. Here are some key tips to maintain safety:

• Keep unused wires capped off so they don't spark and cause fires.

• Take regular breaks to avoid fatigue and sloppy mistakes. Rushing leads to electrocution risks.

• Keep a fire extinguisher and first aid kit handy in case of emergencies. Know where your main circuit breaker is located.

• When using a ladder for overhead wiring, follow proper precautions to avoid falling.

• Avoid working alone. Have someone nearby who can call 911 if an electrical accident occurs.

• Turn power back off immediately if you feel any tingling sensation or shock. Stop work until the issue is identified and fixed.

Conclusion

While rewiring a house is hard work, it can be accomplished safely with proper precautions. Taking the time to assess the existing wiring system, wearing protective gear, turning off power while working, and testing connections thoroughly will allow you to upgrade the electrical in your vintage home without any deadly missteps. Be sure to research your local electrical codes as well. Follow the methods I described, and you can rewire your home without dying!
