FAQ:

Q: How do you use a circuit tester?

A: To use a circuit tester, begin by protecting yourself from electrical shocks by using a circuit tester with an insulated grip. Insert the probe into the main holes of the wall outlet, and monitor the voltage.

Q: What is a circuit tester used for?

A: The circuit tester is used for locating live (battery positive) wires and ground wires. It could also be used for locating and identifying short circuits and battery draws.

Q: What is a circuit light tester?

A: Typically, a circuit tester has a light which illuminates when a circuit is getting power. Some may generate buzzing sounds, and the volume of the sound or the intensity of the light may increase with the amount of power available to the circuit.

Q: What is a voltage continuity tester?

A: A voltage continuity tester is another way to determine if a circuit breaker needs to be replaced. Also called a multimeter, this tool works by using the AC mode and connecting a hot prong with the screw on the circuit breaker.
