Southwire 40022S Receptacle Tester; Black

Works well and made my job easier

I purchased this outlet tester to check that my GFCI plug was functioning correctly and tripping as expected. It not only confirmed that, but it also revealed that I had accidentally wired the outlet with the load and neutral reversed! This tester is incredibly useful—it detects issues like missing ground, reverse polarity, and incorrect hot-wire configurations, while also showing when everything is wired correctly. It's a great value and a must-have tool for anyone who does occasional electrical work. If you're like me and don’t always remember the wiring details, especially for more complex setups, this tester will save you time and frustration.

Absolutely flawless receptacle tester that is childlike-easy to use and performs exactly as described and intended.* Includes a button to also test GFCI outlets as well as standard 125V outlets.* Simple light indications advise proper outlet function or issues* The unit will show outlets that have bent interior connections when initial indications show no power but do when the Tester is wiggled.

So having just replaced a flaky since we moved in over 20 years ago gfci receptacle in the garage (due to loose wire, but also it turns out due to the top plug-in failed when the plug was plugged all the way in), I wanted to be sure everything is now okey-dokey out there. And it is (checked all the plugs inside the garage and outside). Before that I had also tested all the plugs in the master bathroom (aok) and in the kitchen (aok).Also unfortunately I had tested the guest bathroom plugs. It turns out the only (2-plug) receptacle in there did ground fault when tested, but there is no reset button… so now there are no usable plugs in the guest bathroom. At least the lights and fan in there still work. And in this adjacent bedroom I am in, which shares the same circuit breaker, or so I thought. Hmm… where oh where is the reset button (or breaker (nothing looks amiss in the breaker box))?Edit: Following up, I found out that the guest bathroom and the master bathroom (and all the house's exterior plugs) are all tied to the one gfci plug set in the master bathroom. Also figured out what the two kitchen gfci plug sets were tied to circuit breaker wise, and which other plugs went with which gfci plug (not all of the kitchen plugs it turns out are tied to either of the two gfci plugs). So my mapping of all the plugs and light switches for the entire house is now (even more) complete, helped along by knowing which ones are protected from ground faults and which are not. Great investment. I feel a lot safer.

Crucial with the new building codes! My house was built with GFCI breakers, so after a power outage I use this to see which breakers I need to flip, and which GFCI buttons I need to push. Its simple - plug it into the outlet and look at the color of the lights.

Pretty straightforward. Works well for testing outlets. Easy to plug & unplug.

Easy to use, easy to read and very rugged. A little more expensive than the no-name versions of similar products but the build quality makes the small additional cost worth it.
