The Fluke ST120+ GFCI socket tester with beeper checks that each wire in the outlet is properly connected to the building's electrical system. Via the bright LEDs and included chart on the front of the tester, users can quickly and easily verify the wiring of an outlet. Able to identify several common wiring errors, including reversed phase and neutral wires and an open ground, the ST120+ will give users confidence on their next job.
Audible alert helps you work faster, safer
The ST120+ also gives users a unique audible alert anytime voltage is detected. It saves time when trying to identify which circuit breaker is connected to which outlet. The user can plug the socket tester in, walk to the circuit breaker panel, and listen for the beeper to turn off – or on – as they flip the breakers. Once it does, they have found the correct breaker. This saves the user time and money.
When switched on, the integrated beeper can also alert users to hazardous voltage at the outlet, even if the wiring is incorrect. Even while working in an office, hospital or other location where the users does not want to interrupt others, the beeper can be switched off.
One-button GFCI tests
The included GFCI test button on the socket tester allows users to test the operation of GFCI outlets. With a single push, the ST120+ can verify the operation of any GFCI equipped outlet. If the GFCI trips as expected, perfect - the user can move on. If not, it is time for the user tp take a closer look.
