Southwire 40022S Receptacle Tester; Black

Worked as promised to check the wiring of a gfi outlet and to test the ground fault mechanism.

Works great, and great value

The tester was very easy to operate. It was accurate each time I used it . Easy to read results . Great tool for DYI . I recommend this tester.

This works just like it should. I dont have a hard time seeing the lights. It was a good price and gets the job done.

Works as advertised!

Good quality. Definitely recommend.

Excellent high quality product with LED table which makes it crystal clear on whether your GFCI outlet is functional or has any issues. Definitely a bargain at the sale price.

This tool does what it is designed to do. Read the design parameters. This is a basic tool....detects common defects. Keep in mind that poorly installed electrical systems can have a baffling combination of errors. If the solution to your problem is not immediately apparent...seek qualified help!!!

Our LED lights flicker when the washer is running so I was worried that we might have a wiring problem. I used a multimeter on a few outlets but determining problems using a multimeter is a multi step process and Im always worried about breaking the multimeter sticking it into live sockets. This tester is so much simpler and gives immediate results. I was able to check every outlet in the house within 10 minutes. I found a few that were wired in reverse, which is an easy fix.

With two work sites and two tool boxes, I decided to get another outlet tester. At $9 this Southwire is a good value these days. Easy to use - just plug it in. Two yellow/orange lights means good. Red or any other combination means something is wrong. However in daylight it can be difficult to see which orange/amber is lit.
