Most electrical repairs should be made by a professional. But for all you "do-it-yourselfers" out there, here are tips on how to stay safe when dealing with your home electrical systems.
The Electrical Panel
Every time you use an electrical device in your home, power runs through the electrical panel, causing it to heat up and cool down constantly. These temperature fluctuations cause your home’s electrical panel to fail over time—the lifespan of a typical modern electrical panel is around 15 to 20 years. If you have a fuse box or another older-style electrical panel (you’ll usually see these in homes wired prior to the 1960s), it’s recommended to replace it with a modern circuit breaker-style electrical panel as soon as possible. You should also confirm that:
If you aren’t sure what to look for in your home’s electrical panel, your local NPI inspector can identify issues and fixes for you.
Switches and Outlets
Your home electrical safety check should also include switches and outlets. You should confirm that each switch and outlet in your home is functioning correctly, and that you have ground-fault circuit interrupters (GFCIs) installed in rooms like the kitchen and bathroom where outlets could come into contact with water. If you notice anything unusual, it’s time to call in an electrician to fix the issue. Here are some potential problems to look for:
Making sure electrical cords are in proper working order is key to preventing accidental shock and risk of fire. You should make sure that large electrical appliances like window air conditioning units are plugged directly into a grounded wall outlet, and that electrical cords are placed away from high-traffic areas to avoid tripping.
Electrical appliances make life easier, but you have to know how to use them correctly to avoid the risk of shock and fire. Major appliances like your refrigerator, stove, clothes washer and dryer need to be plugged into grounded wall outlets. For heat-producing kitchen appliances like toasters and waffle irons, plug only one appliance into a receptacle at a time to avoid overheating.
Your outdoor electrical system improves the appearance and safety of your home, and it should be inspected regularly by a qualified home inspector. An inspector will check for various safety issues, including whether your exterior outlets are equipped with GFCIs or covers and your home’s exterior lighting system is adequately weather-proofed.
