Southwire 40022S Receptacle Tester; Black

Only real complaint is that I was hopping the lights were LEDs and therfore a littl brighter, but for the price is is bright enough and works perfect. The GFIC tester is a nice thing to have.

Easy to use and fool proof design. Made it simple to check all the outlets for a new house the we purchased. Actually was able to find several outlets that were wired incorrectly and able to get seller to repair then before the closing on our pre closing inspection.

Never use one of these before, but I was testing outlets in the house just to see what would happen with the different outlets and actually found an outlet where the ground was never attached when the house was built

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

This is awesome! Even if you dont wire outlets yourself, you should check your outlets. This tool helped me to see there was an issue with a ground wire. The ground wire had a small hidden break in it and I was able to locate it and fix it. Without this tool, the outlet would work, and I wouldnt have known that it could be a shock issue. Very helpful!

Working

Very useful tools, easy to use and safe

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.

Needed a quicker method to verify that 110 AC Volt home receptacles were safely wired when using a grounding mat. I verified its operating with the AstroAL Multineter Voltmeter.

Works the same as they always do and did, including the flaw that wont correctly identify a dangerous condition. Look up reverse polarity bootleg and youll see what Im talking about.
