Southwire 40022S Receptacle Tester; Black

the test button is great! very easy to test all your GFCIs

Good quality. Definitely recommend.

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 houses 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.

Not sure how accurate this really is. Plugged into an outlet that definitely was ungrounded and it didnt give the proper lighting config for that. Its a good first reference but I wouldnt rely on it solely.

Saves time. A must for all homes

It tells me what I need to know and works great!

Got this to trouble shoot an outlet in our home. Works great, durable construction, and super simple to use. Just plug it in and read the lights. Legend is printed right on the device to tell you what youve got.

Definitely not the best

Item was delivered as promised. I use this tester not only in my home but also to check the main breaker at the campsites I have visited to ensure that the polarity is correct before connecting my travel trailer to the 30 amp service. The indicator lights make it easy to verify

Tester is exactly what I needed - much better price at Amazon than at Lowes or Home Depot
