Wiring Repair Guide

Wires help transfer the electricity that makes your house a home. They keep your lights on, your refrigerator running and help you enjoy watching television and listening to music. But when there’s a problem with your wiring, your home life comes to a grinding halt.


In 2010, the average annual electricity consumption for the U.S. was 11,496 kilowatt hours (kWh), an average of 958 kWh per month. That’s according to the U.S. Energy Information Administration.


There are a number of things that can go wrong with your home’s wiring. They can range from minor inconveniences to major safety hazards. When you are experiencing problems with your home’s wiring, the safest bet is to call up a professional to handle it right away. That doesn’t mean you should stay in the dark about the repair process. This guide from will guide you through the basics of wiring repair.

  1. 1.First, A Word About Safety

    You could get yourself into big trouble by taking your home’s electrical wiring into your own hands.

    You could get yourself into big trouble by taking your home’s electrical wiring into your own hands. Electric shocks can cause serious injury or even death. Also, faulty or improperly installed wiring can spark deadly fires inside your home. Don’t ever do anything involving electricity that you aren’t 100 percent sure of. And any time you do decide to do any kind of work on your home’s wiring, make sure to turn off the circuit at the main breaker panel.

  2. 2.What is the problem?

    Because most of your wires are hidden behind your walls, it can be tough to tell when something is going wrong. Some common hints that you might be experiencing problems with your home’s wiring are: flickering lights, hot lights or extension cords, a persistent burning smell, breakers that trip over and over again, a tingling sensation when you touch an appliance, or an appliance that refuses to work even though it appears to be in working order.

  3. 3.Can you figure out the solution?

    There are some easy things you can do to figure out the problem. If an appliance that seems fine just won’t turn on, try plugging in another appliance. Inspect your outlets to make sure they are free of dirt and dust. Sniff around – do you see smoke or smell something burning? Those are signs that you should call a professional to take a closer look right away

  5. 4.Contract the job out.

    When it comes time to hire a professional electrician, what should you look for? Make sure your professional is licensed to work in your state. You should also make sure he or she knows the proper codes and procedures to go through to complete your project.


    Always ask for references. Make sure you get a quote in writing and a good estimate of how long the project should take.

  6. 5.Things you can do.

    There are some jobs that anyone can do at home. Keep your electrical panel in tip-top shape by inspecting it every once in a while. Make sure that it’s not exposed to moisture in any way, which can not only cause corrosion, but puts you at good risk of electric shock. Treat your panel with dielectric grease, which helps seal out moisture. Ground Fault Circuit Interrupters (GFCI) are vital to have in your home wherever water is nearby. They shut down the electric current to protect you from severe electric shock. You can buy a GFCI outlet for less than $20 and install the panel in a few short steps


    A good wiring system is vital to have and expensive and time consuming to overhaul. Take care of your home’s wiring and your home’s wiring will take care of you!
