Outlets
Check for loose-fitting sockets and wiring, and replace missing or broken wall plates and housings — inside and out. Make sure you’re not overloading an outlet with too many plugs. And if you have young children, place safety covers on unused outlets.
Appliances & Other Electrical Devices
Check cords, plugs, and connectors for any fraying, cracking, or other damage. If an appliance repeatedly blows a fuse, trips a circuit breaker, or gives off an electrical shock, unplug it immediately. Do not use damaged appliances until you can have them fixed by a qualified repair shop. Do not place cords under carpets or rugs, on top of furniture, or across any high-traffic areas. And never use nails or staples to secure cords to walls, floors, or any other objects.
Extension Cords
These are not a permanent wiring solution. If an outlet is not located where you need one, hire a certified electrician to install a new outlet. For temporary use, make sure any extension cords you use have safety closures and keep them away from young children. Never use an indoor extension cord for outdoor use.
Electrical Panel
Make sure that all breakers and fuses are properly rated for the circuit they protect. When replacing a fuse, use the same size as the one that you are removing. It’s a good idea to hire a certified electrician to identify and label the correct size for each circuit.
Light Bulbs & Fixtures
Be sure to use the proper wattage light bulb for each fixture. Each bulb should be screwed in securely to prevent overheating.
Bathrooms, Kitchens, & Laundry Areas
Use ground fault circuit interrupters (GFCIs) on all outlets in any wet area of the home. These inexpensive devices shut power off instantly if there’s a problem, and should be tested on a regular basis (using the test button installed in the outlet).
