The Klein Tools ET310 Circuit Breaker Finder with Integrated GFCI Outlet Tester is a precise and efficient tool for electricians and homeowners. It quickly and accurately identifies the correct breaker in a panel to which an electrical outlet or fixture is connected. Operating on 90–120V AC circuits, the device includes a transmitter that plugs directly into outlets and a receiver that scans circuit breakers with visual and audible feedback when the correct breaker is located. The transmitter also functions as a GFCI tester to verify outlet wiring and test GFCI devices. For added convenience, the transmitter docks into the receiver for compact storage. Built for jobsite durability with a 6.6-foot drop rating and a CAT II 120V safety certification.
