Our Circuit Breaker Finder w/ LED is used for identifying the correct circuit in an electrical panel in residential and commercial applications. The Circuit Breaker Finder is comprised of a Transmitter and Receiver that can be used for standard 120V panels with a safety rating of CAT II 135V. This all-in-one solution stores the Transmitter into the Receiver to allow for easier storage and transport on a jobsite. With the LED work light, you can easily work in dark areas with more visibility, and the over molded grip provides durability and comfort for all applications.
