How to Use Cheap Electrical Testers
Three testers make electrical work safer and easier — and for less than $20, you can own them all.
IntroductionWe'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.

How to Test Electrical Outlets and How to Test a Light Switch with a Non-Contact Voltage Tester
- This is the safest tool to confirm that electrical power is off, even before you touch a wire.
Test the Receptacles
- Test receptacles with an electrical outlet tester to make sure they’re off before removing them.
- Turn the power off to the outlet.
- Shove the electrical outlet tester nose into the narrow (hot) slot of the receptacle.
- Note: The tester will light and chirp continuously if the power is still on.
