Description
Circuit Breaker Finder Tester Kit with GFCI Outlet Tester and Non Contact Voltage Tester
-
The right breaker in two scans: this electrical breaker finder lights up and beeps when the correct breaker is found
-
No guessing at the panel: the transmitter plugs into an outlet and the receiver scans the circuit breaker panel
-
Outlet faults spotted fast: the GFCI and wiring analyzer diagnoses 7 wiring conditions and tests GFCI devices
-
Readings you can verify: the backlit LCD displays real-time voltage and fault status for instant verification
-
An extra layer of safety: non-contact voltage detection adds protection to every check
Finding the right breaker should take two scans, not a round of guessing. The receiver lights up and beeps when it finds the correct breaker, so the answer is clear without a second pair of eyes, whether you are working at home or on a commercial site. It works on 90–120V AC for home or commercial use.

The two-part system is simple: the transmitter plugs into an outlet and the receiver scans the breaker panel, so it works as a circuit breaker tester and electrical tester in one. As a GFCI tester and receptacle tester, it diagnoses 7 wiring conditions and tests GFCI devices, and as an electrical outlet checker the backlit LCD displays real-time voltage and fault status. Its NCV tester function is non-contact voltage detection, a voltage detector that adds an extra layer of safety. Treat every circuit as live and follow standard electrical safety practice.
