Why Rewiring Your Home Can Be Dangerous

Rewiring a home can be extremely dangerous if proper safety precautions are not taken. As a homeowner, I never realized just how hazardous working with electricity could be until I decided to rewire my house.

Handling electrical wiring when the power is still flowing can result in electrocution, burns, shocks, fires, and even death. This is why it's absolutely critical to shut off the main power to the entire home at the main electrical panel before beginning any rewiring project.

Even with the power off, simply working inside the electrical panels and handling the wiring carries risks. Bare wires can still deliver dangerous shocks and electrocution if mishandled. One small mistake working inside the electrical panels can have catastrophic results.

This is why rewiring a home requiressuch an incredible amount of care and safety consciousness. Rushing the job or not giving it your full, undivided attention can put your life at risk.

Safely Preparing for a Rewiring Project

Before beginning any rewiring, the first step is to educate yourself as much as possible on home electrical systems. Understand how the current wiring works, where the power originates from, and how to safely shut it off.

I spent several weeks reading books and watching online tutorials before feeling fully prepared for my rewiring project. The more you understand the fundamentals, the safer you'll be working with the electrical system.

You'll also need to purchase some basic safety gear:

It's critical to methodically verify the power is shut off at every point before handling any wiring. I cannot emphasize enough how important it is to take zero risks when it comes to verifying the electricity is off. Always double and triple check.

Step-by-Step Process for Safely Rewiring

Once you've acquired the right knowledge and safety gear, follow these steps to safely rewire your home:

1. Turn off the main power at the panel

Locate the main circuit breaker panel and switch the main breaker to the fully off position.

2. Verify power is off

Use a voltage detector or multimeter to methodically check every outlet, light fixture and switch. Verify zero electricity is present before proceeding.

3. Disconnect the old wiring

With the power confirmed off, carefully remove any old or damaged wiring from the electrical panels. Work slowly and methodically.

4. Install new wiring

Refer to your electrical plans and neatly install the new wiring. Double check connections are tight.

5. Carefully re-energize circuits

Once all new wiring is installed, slowly switch each circuit back on one at a time. Continually verify no issues.

6. Test all electrical fixtures

With all power on, methodically test every outlet, light and switch. Ensure proper operation.

Rewiring your home in this safe, step-by-step manner will allow you to upgrade your electrical without risking electrocution. Never take shortcuts when it comes to safely handling and installing wiring. Always put safety first.

Common Hazards and Mistakes to Avoid

Here are some of the most common hazards and mistakes that can turn a rewiring project deadly:

By being alert and avoiding these hazards, you can rewire your home with greatly minimized risk.

When to Call an Electrician

While minor rewiring tasks can safely be DIY, larger whole home rewiring jobs or electrical panel upgrades should always be left to professional electricians.

The risks exponentially increase when rewiring at the main panel and service entrance. Mistakes here can be catastrophic and potentially fatal.

Only tackle small scale, straightforward rewiring projects on your own. Anything major should only be done by licensed electrician. Don't take unnecessary risks with tasks beyond your skill level.

By educating yourself, taking proper safety precautions, and avoiding common hazards, you can successfully rewire your home without electrocution. Just be sure to always put safety first.
