The Major Tech Circuit Breaker & Fuse Finder is a professional two-part system designed to quickly identify the correct circuit breaker or fuse protecting any outlet or circuit. The transmitter plugs into a socket outlet and sends pulse signals along the circuit to the distribution board, while the handheld receiver scanner automatically locates the corresponding breaker via green LED indicator and continuous tone alert. Ideal for electricians, facilities managers, and maintenance technicians who need to safely isolate circuits without trial-and-error testing.
