Southwire 40022S Receptacle Tester; Black

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

This is great for checking and replacing receptacles. You can be sure that youve turned off the right breaker before getting to work. You can be sure youve wired things correctly when youre done. Its easy enough to use that you wont be tempted to cut corners with your safety.

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

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.

worked just right as around house DIY

I had to replace all of the GFCI outlets in my house (see my public profile for more details if you are curious, amazing GFCI outlets) and I bought this tool to ensure they would be wired correctly and function. There is a little button on the front which causes a ground fault, to test a GFCI. It worked like a charm and showed me each time if I had made any mistakes. Im glad it did, as I had actually switched around one of my outlets but fixed it later, thanks to this device. In all, its a fantastic product for a fantastic price. I have no complaints whatsoever and think it is the perfect addition to an electricians toolkit!

Saved the price of this unit 10 times over on the first job with GFI problems.

Husband had fun testing every outlet Works great!

Better than I expected

This product has worked every time I needed it to. Great for testing GFCI outlets. Came in handy when troubleshooting a wiring issue on an electric scissor lift. I thought the wiring to the platform for AC voltage was faulted. Turned out my known good extension cord was cut internally and did not have a ground. The tester showed this immediately. Then I verified with a meter. I also use this for rental generators to verify a voltage output and test GFCI functionality. Works awesome for a quick check.
