They are all around us. Also known as outlets and wall plugs, electrical receptacles are convenient resources for tapping into the power of electricity. They are relatively simple in operation, so there is little to go wrong. However, when you've tested and replaced everything else except the electrical receptacle, it's time to give it a quick check. Luckily, it's a relatively easy task.

How Does It Work?

This new receptacle has both terminal screws (sides) and wire slots (back).

An electrical receptacle or outlet is a socket into which the wiring for portable lamps, appliances, and other electrical devices can be plugged. It provides the connection between the building's electrical circuit and the corded appliance or other device that requires electricity to operate. Receptacles in older homes have two holes, hot and neutral, while newer homes add a third hole for a grounding connection for safety.

What Can Go Wrong?

Receptacles crack and develop shorts. They may not hold plugs in place securely. They can be the wrong color or paint splattered after you paint. Receptacles are inexpensive and easy to test and replace.

It's a good idea to invest in an electrical receptacle analyzer. Why? Because it's cheaper than repairing the damage caused by a bad receptacle. For example, before plugging your expensive stereo or other device into an outlet in your new home, test it to make sure that it is properly wired and grounded. A combination of glowing lights will tell you what is happening with your receptacle.
