ST120+ Overview

The ST120+ not only provides a GFCI test button but also offers a distinctive audible warning whenever voltage is detected. This feature can help you save time when trying to determine the connection between a circuit breaker and an outlet. Simply plug in the socket tester, walk over to the circuit breaker panel, and listen for the beeper to either switch off or on as you toggle the breakers. Once it does, you've identified the right breaker, saving you time and effort.

Plus, when activated, the built-in beeper can warn you of dangerous voltage at the outlet, even if the wiring is faulty. If you're in an environment like an office or hospital where you don't want to disturb others, there's no issue - the beeper can be turned off.
