Klein Tools Gfci Receptacle Tester With Lcd

another tool to the tool box!

Didn't really need this device as I would just use a multimeter to very the outlet is correctly wired; however, with newer outlets with built-in safety covers it's near impossible to get the probes into the outlet. It also prevents the use of alert voltage tester to see if the outlet is live. This unit tests the outlet wiring and verifies that the outlet is live along with testing GFCI circuits. A must have device when needing to verify an outlet is live or correctly wired that has built-in safety covers.

Gives false readings when voltages are abnormal or when the neutral has back feed, very misleading, waste of money, I would return item but it's a hassle, just sits in my toolbox now

Any problems with low voltage? This will tell you. Checks wiring on receptacles and gfci receptacles. Love the fact that it also shows what your voltage is. Had a jumpered receptacle once and power was low due to corrosion from another. This would have told me everything from the start. great tool to keep on hand.

A outlet voltage tester with GFCI testing too. What a great device.

[This review was collected as part of a promotion.] Since the day of purchase it along with other klein tools has been my go to ! , checking polarity (correct wiring) , and voltage ! , preventative maintenance is key and the RT250 completes this with the professional touch.

It is a nice general purpose tester. But I discovered a problem. It does not identify a NEMA 5 outlet that was wired to 240 volts (circuit was incorrectly labeled). All the RT250 said was 30v ground/hot reversed. It had a stern warning that it was limited to 120v. The RT250 needs to be redesigned to handle this situation and report the fault..

I wish it was rated for up to 230v. In an entertainment 3 phase system, it's possible to accidentally have an outlet connected to two hot legs instead of a hot and neutral. This tester is only rated for up to 135v. I'm afraid if I come across this situation it will fry the tester. Because of that, it's not that much more useful to me than the old-stye, 3 bulb tester, and it's twice the size.

This is my overall favorite tool I work commercial electrical and every time I am changing a outlet I pull out this bad boy to make sure it's wired correctly and reviving proper voltage at same time I just hope they make one for 277v that would be amazing.

I bought this tool after watching a video about it and I'm so glad that I did, Not only is it a great circuit tester but you can also see the voltage as well. And the voltage is very accurate too. With the GFCI tester, this makes a great all around circuit tester for any electrician no matter your skill level. And with the small price tag, makes it even better!!
