Klein Tools ET310 Digital Circuit Breaker Finder
The Klein Tools ET310 is a digital circuit breaker finder designed to accurately locate and identify the correct circuit breaker in electrical panels. Operating on 90V to 120V AC (50/60Hz) indoor electrical systems, this diagnostic tool utilizes both visual and audible indicators for clear circuit identification. The system consists of a receiver used to scan the breakers in the panel and a transmitter that connects to the specific outlet or fixture being traced.
The transmitter features a standard 3-pin plug and includes an integrated GFCI outlet tester. It provides illuminated wiring condition indicators that correspond to a reference code chart printed directly on the unit. For convenient storage and transport, the transmitter securely docks into the receiver housing.
