Locating the right breaker shouldn't feel like a guessing game. This unit is unopened and arrives in its sealed retail package. The Sperry Instruments CS550A is a professional-grade solution designed to quickly and accurately identify which circuit breaker or fuse supplies power to a specific outlet. This tool is essential for anyone looking to map out a home or workplace electrical system safely and efficiently.

The system features a dual-component design: a transmitter that plugs into the live outlet and a hand-held receiver that scans the breaker panel. With both visual and audible indicators, you get immediate confirmation without having to interrupt electrical service or run back and forth between rooms. Whether you are performing routine maintenance or preparing for an electrical upgrade, this tool brings precision and confidence to the job.
