About Circuit Testers

A circuit tester is a device used to verify that an AC wall outlet is wired properly. The tester itself is small device which looks like the "plug in" end of a power cord, with several lights on it rather than an attached cord. Be sure to get one today, and avoid the unpleasant mistake of finding out a plug is hot, when you thought it wasn't. It could even save your life!
