Southwire 40022S Receptacle Tester; Black

Great little device. Helped me locate a bag GFI in my house and a neighbors house.

Easy to use

Very useful tools, easy to use and safe

Does its job. Great price

Apart from lights not being very bright in a sunny room, it works very well.

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.

I set out on the adventure of replacing the old dark brown AC receptacles in our den, which used to have dark wood paneling on the walls. The room is now white, so the dark brown switches and AC outlets stick out like sore thumbs. This outlet tester has been an invaluable tool in the process. Not only can I make sure that I turned off the correct circuit at the breaker box, but it also let me know that I didnt properly secure a neutral wire on one of the receptacles, which made all of the other outlets in the room read as hot/ground reversed. That would have been difficult to diagnose for an amateur like myself if it werent for the tester readout. I also got a contact-less tester, which has been a huge help in making sense of the puzzling wiring decisions that the builders made in parts of our 40-year-old house. Between these two tools, Ive been able to safely and (somewhat) confidently meddle with the AC outlets and light switches in our house.

I wanted to add this item to my diagnostics kit. It should be helpful when I get to use it.

The unit seems to work well and identify troubled outlets and wiring issues but the test lights are not very bright to the naked eye and are even worse in a photograph. As a home inspector, this gets a lot of use but the photos dont turn out well. I have better luck with my outlet tester from Harbor Freight reading the test lights.

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