Circuit Breaker Finder with GFCI Tester

This tool combines a digital receiver and plug-in transmitter to locate the correct circuit breaker quickly. It is designed for DIYers, homeowners and electricians who need to trace circuits without guesswork. The kit includes a carrying case and four adapters for different outlet types.

Audio-Visual Alerts and Voltage Range

The receiver beeps and flashes red when it detects the target breaker, while a built-in LED light helps illuminate dark panels. Operation covers 90120V AC at 50/60Hz, matching most standard household systems. Auto-shutdown and low-battery warnings reduce unexpected interruptions during use.

Adapters Expand Connection Options

A light-socket adapter, 3-to-2-prong adapter and alligator-clip adapters let the transmitter connect to fixtures, older outlets or bare wires. The integrated GFCI outlet tester checks wiring conditions and confirms ground-fault protection function. All components store neatly in the supplied carrying case.

Questions about this item

How do I install the transmitter into a light fixture, and which adapter do I use?

Screw the light-socket adapter into the fixture, then plug the transmitter into that adapter; the 3-to-2-prong adapter is for standard outlets only.

What maintenance will the receiver need over time?

Replace the batteries when the low-battery alert sounds; the auto-shutdown feature helps extend battery life between changes.

What voltage limit stops the tool from working on a circuit?

The transmitter operates only on 90120V AC at 50/60Hz, so circuits outside that range will not be detected.
