## Description

"The ST120+ Socket Tester with a GFCI test button and beeper from Fluke is the perfect tester for electricians and electrical inspectors, home inspectors and technicians who need to verify the correct wiring of outlets. The bright, easy to see LEDs let you know if an outlet is miswired and the integrated GFCI test button gives you peace of mind by allowing you to verify the proper operation of GFCI equipped outlets. The addition of a switchable beeper makes the ST120+ even more capable. In addition to providing an additional level of safety by beeping whenever voltage is present – even with a miswired outlet – the beeper also helps you save time identifying circuit breakers. Just plug in the tester into an outlet and make sure the beeper is switched on. Then, when you flip the corresponding circuit breaker for that outlet, the beeper will turn on or off, letting you know that you found the right breaker. These features packed into the compact yet rugged design of the ST120+ make this the perfect tester to take to every job."

Review: As an electrician who often works alone, the Fluke ST120+ GFCI Socket Tester with Audible Beeper has become an essential tool in my bag. The audible beeper is a game-changer—especially when I'm troubleshooting or trying to shut off a circuit and the panel is out of sight but within earshot. Being able to hear the tester respond saves me time and steps, and the sound can be turned off when not needed. It’s built with the quality you expect from Fluke, and while it’s a little pricier than some other GFCI testers, the reliability and added features are more than worth the cost. I’ll continue to repurchase this tester and highly recommend it to anyone in the trade.

## Questions & Answers

**Q: Does this work to simply test if an outlet is working  ( I'm not an electrician, so in other words if it's "hot" ) ? Even not talking about gcfi.**
A: Yes, this outlet tester will verify that there is current flowing in the socket ("live"), but importantly, it will tell you if the socket is wired correctly.  Sometimes electricians or "DIYs" wire receptacles incorrectly, putting the neutral wire to the hot terminal and the hot wire to the neutral terminal, which will work but which will make some electrical devices unsafe to use.  This will tell you immediately if it is wired correctly, it primary function.

**Q: Can I attach a 3 prong adapter to my 2 prong outlet then test with this device?**
A: The whole point is to test all 3 conductors to assure they are in the right orientation.  But, I bit and tried it out of curiosity.  Drum roll please - Open Ground!  But you probly knew that.

**Q: Does this fluke st120+ gfci socket tester come with a standard warranty, e.g. 12 or 24 months?**
A: This model has a 2 year warranty.
