UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light

50+year old building. Built on 3 times. 3 rental units. 5 breaker panels. This tool was a life saver for me.

Finds breaker very well but says I have open ground and I got out my tester I know is good and it say they are fine. The tester part is inaccurate

Remodeling the house and replacing sockets to current codes, this is an old house. Circuit breaker finder helped me find the right lines to turn off. Easy to use and in my low budget raange.

Be sure to read the instruction manual. Purchased this to trace a circuit....and it worked flawlessly. Highly recommend.

I wish I had one of these a long time ago. It works for me. As long as you understand you need to start out with the receiver on high sensitivity them gradually decrease it to lower sensitivity (go from general to specific to zero in one the exact breaker), you should be fine. The transmitter device seems to be exactly like one I already owned and are sold by themselves. It may just send some kind of signal the receiver detects. If you have an old home with multiple wiring revisions done over the years, this is a kit that will save you a lot of time.

Its a useful combination tool for testing outlets and identifying circuit breaker for that outlet.

This device gave incorrect readings from the outlet to the breaker box.

Works pretty good considering the price. New it wasnt top of the line going in.

My house was built in the 1950s and added on to many times by people that didnt always know what they were doing. As a result, my wiring is a hodgepodge mess with outlets on different sides of the house sharing the same circuit in some cases. This unit worked on a few of my circuits, but most were not accurate at all (would signal on the wrong circuits). I have a mix of double and single pole breakers, all covered by a sheet metal panel. Playing with the sensitivity seemed to help, but it varied so much from circuit to circuit that I found it was faster to just start flipping breakers on and off while talking to my wife on a hand held radio rather than fiddling with the sensitivity setting each time. The unit seems well made, and is very easy to use. It would probably work much more effectively on a newer house with newer (and cleaner) wiring. But for my situation, it didnt work at all unfortunately.

This kit takes the guesswork out of testing electrical outlets, and it speeds up circuit breaker identification by narrowing the possibilities to a manageable number. I only wish that the receiver wand was equipped with a signal strength indicator, for better accuracy while finding breakers. The plug-in outlet tester/transmitter works well, with bright lights that are easy to see. A color-printed decoding chart is conveniently included on the label, making it simple to interpret the results. The test button works as it should, causing my bathroom/garage GFCI outlets to trip immediately. The tester is ETL Listed, giving confidence that the kit is safe to use. The circuit breaker finding/receiving wand gets the job done, but it’s imprecise in operation. The wand tells you (with beeping and a flashing light) when it detects a signal from the outlet tester, but it’s either alerting or not, with nothing in-between. That’s not ideal, as on my electrical panel, the wand alerts on up to five breakers simultaneously, and adjusting the sensitivity doesn’t help. Having some indication of signal strength might narrow that down to one or two breakers, but this unit offers no such help. Overall, this is a decent testing/locating kit, but the wand could be better at telling you what’s going on. As it is, the kit can locate breakers to within a handful of possibilities, and that’s certainly better than nothing, but I had hoped for a little more precision.
