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

Tried this in my office. Very difficult to calibrate. I could never narrow it down to just one circuit breaker.

UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light this is a sweet little gadget! Wish I had one of these when I was still doing remodeling work. Back in the old days youd have to plug in a light, 5hem hollar over to your buddy wife for kid, generally from the basement, hey! did it go out yet? Nope. Not yet... None of that nonsense with this little guy. Basically no problems getting it to work You start at the highest sensitivity and it did beep on about 4 circuit breakers then you dial down the sensitivity and then it didnt beep at all then you dial it up a just a little bit and then it beeps on just one breaker. brilliant. Just brilliant. One thing I did notice though is I have a power strip plugged into a power strip plugged into another power strip and I put the transmitter into that last power strip and that did not show up at the panel. So it does seem To be better if you plug the transmitter directly to a wall outlet. Would absolutely recommend this.

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.

We have a home built in 1959. The breaker box has a few labels, but they mostly identify the 220 circuits for the stove top, oven, dryer and water heater. As for the rest of the circuits for lights and outlets, few of them are marked and Ive found a couple of them marked wrong. This works best with two people so you dont have to keep running back and forth. The sending unit is plugged into an outlet and the receiving unit is passed over the circuit breakers. When you have the active circuit, the receiving unit lets you know. Once you have gone through your whole house, there is never again that need to flip circuits on and off trying to find the right ones.

When used it show a few breakers so I found my self cycling breakers that were near it till I found the right one. However once you open the right breaker the device wont sound so it does work.

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.

Could not adjust to work on any breakers, junk

This device is very easy to use and allowed me to determine a problem with the house wiring in the circuit breaker cabinet. I contacted an electrician and he was able to resolve the problem which could have resulted in damage to appliances and devices plugged into the affected outlets. I dont understand the whole issue but it had something to do with the neutral leads. The symptoms were this device sounded off on multiple breakers for widely separated outlets. The electrician was able to fix the issue fairly quickly and once he finished the device worked flawlessly.

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

Its only natural for the signal injected at the outlet to bleed over to other circuits. The receiver has to be able to filter the lesser signals and only beep on the strongest. This one does not. It signals on too many breakers to isolate the one I want. So, I took it out to my shed with 6 outlets and 3 breakers in the whole box. It signaled strongly on all 3 breakers. I moved it around and it still signaled on all 3. I spent quite a bit of time adjusting sensitivity to no avail. Im returning it and will hit the Home Depot a little later for a Klein. Oh, and the circuit tester shows open neutral on all breakers.
