Introduction
We'll show you how to use inexpensive electrical testers to make electrical work safer and easier. We cover three testers — a non-contact voltage tester, a circuit tester and a continuity tester. You can buy all three at home centers for about $20. Then you'll never have to worry about getting shocked again.Tools Required
