Do it Yourself Guide to Checking the Integrity of Existing Electrical Outlets

It is always a good idea to check all of the electrical outlets in your home prior to beginning any other home improvement project. A main reason for this is that many homes that were constructed in the 1950s, 60's and early 70's (and even earlier) were built under different codes and different levels of technology.

In many cases the electrical outlets have only two prongs, which means that they are not grounded. An ungrounded outlet can be a potential hazard to today's sensitive electronic equipment such as computers, DVD players, and televisions. These outlets should be changed to three-pronged, grounded outlets with appropriate grounded Romex style wiring. While you're checking the outlets, look for any that may be cracked or broken as these should be replaced immediately.

It's also a good idea to purchase a plug-in type voltage tester. This device has three LED lights that indicate whether or not the outlet that it is plugged into is wired correctly. There is a chart on the tester itself which shows what each light combination means. If you plug the tester into an outlet and the outlet is wired backwards (incorrect polarity), if it has no ground, has lost its neutral, or even if it is wired correctly, the lighted combination pattern on the tester will indicate the status of each of these as they exist.

Also, it is very important to check the electrical outlets that are installed near your kitchen and bathroom sinks. These should be GFCI outlets (Ground Fault Circuit Interrupter). These outlets are designed to instantaneously trip to prevent electrocution. On the outlet, there are two buttons. One is marked "Trip" and the other is marked "Reset". If they are regular electrical outlets, replace them with GFCI outlets. If the electrical outlets in fact are GFCIs, insert a plug-in voltage tester (as previously mentioned) and press the "Trip" button. The tester's lights should go out. Press the "Reset" button and the power to the GFCI outlet should be restored. If the outlet doesn't work in this manner, replace the GFCI. Be certain to follow all manufacturers recommendations and instructions regarding installation.

A complete inspection of the electrical wiring can be done by a qualified home inspector or a licensed electrician if necessary to ensure that the electrical panel and wiring inside the walls are in compliance with local regulations and building codes.

Once you have determined that the electrical wiring in your home is up to date and safe for you, your family, and your sensitive electronics, you'll be fully prepared to take on all other home improvements with confidence.

Remember, always work safely.
