Klein Tools ET310KIT Digital Circuit Breaker Finder Kit with GFCI Outlet Tester Light Socket Adapter Alligator Clips and Hard Case

Eliminate the Guesswork: The Complete Solution for Locating Circuit Breakers

Take the frustration out of electrical diagnostics with the Klein Tools ET310KIT Circuit Breaker Finder Kit. Designed for both residential and commercial applications, this professional-grade set allows you to quickly and accurately locate the correct circuit breaker in a panel without the need to interrupt power to the entire building. The system operates on standard 90-120V AC circuits and uses a two-part design: a transmitter that plugs into the electrical outlet or fixture, and a receiver that scans the panel to pinpoint the exact breaker controlling that circuit. This ensures you can work safely and efficiently, turning off only the specific circuit you need to service.

This kit goes beyond simple detection by including a comprehensive set of accessories to handle a variety of wiring scenarios. The transmitter doubles as a GFCI outlet tester, allowing you to inspect wiring conditions and verify safety compliance. With the included light socket adapter, you can easily find breakers for ceiling fixtures and chandeliers, while the alligator clip adapter enables connection to bare wires on non-terminated circuits. All components are protected and organized in a rugged, premium hard carrying case with a custom foam insert, making it an essential, grab-and-go addition to any electrician's or maintenance pro's toolkit.

Pro-Tip: To ensure the highest accuracy, scan the breaker panel twice. The first pass allows the microprocessor to learn the panel's signal strength, while the second pass will pinpoint the exact breaker with a solid green light and a distinct tone.
