Circuit breakers are very convenient and common safety devices used to protect your electrical system from overloads and other hazards. But unless your electrical service panel (circuit breaker box) is very carefully mapped, it can be difficult to identify which breaker controls which outlets, switches, or light fixtures.
When an overload or short circuit "trips" a circuit breaker, it easy to identify, as the lever on the breaker snaps to the "off" position. But when you are doing home repair work and just want to turn off a circuit feeding an electrical outlet or light fixture, finding the correct circuit breaker to turn off is usually a two-person job involving you at the circuit breaker box, an assistant at the outlet, and a good deal of shouting back and forth.
A great little device that simplifies this task is an electronic circuit breaker finder, which easily locates a circuit in a breaker box and makes this all a one-person job. These devices work for either circuit breakers or fuses and are very easy to use.
- The tester consists of two parts: a Transmitter, connected to the electrical outlet or fixture and a Receiver, used to scan the panel to locate the correct breaker.
- The receiver delivers clear visual and audible indications when the correct breaker has been located.
- Operates on 90-120V AC circuits.
- Transmitter incorporates a GFCI outlet tester to inspect the wiring condition at the electrical outlet and test GFCI devices.
- Transmitter docks in the Receiver for convenient storage as a single item when the tester is not in use.
- Transmitter incorporates a three-pin plug for connecting to North-American-style grounded electrical outlets.
- The transmitter may be connected to other electrical fixtures using optional accessories that are sold separately (Cat. No. 69411).
- Receiver powers off automatically after approximately three minutes of non-use to conserve battery life.
- The transmitter is powered by the circuit when connected to the electrical outlet or fixture.
- Low battery indicator.
- Easily accessible battery compartment. Uses one 9V battery in receiver only; Transmitter does not require a battery.
