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

We had changed out our load center some years back and never got around to labeling the breakers, well thats not good. When you need to know, you often need to know at that exact moment, what breaker is what, so I took this thing and was able to quickly go from room to room or outlet to outlet and find the source breaker/circuit, now no more headaches when I need to find a particular one. This also makes a great NCV detector, so once its duties are done as a finder in the home it can still be helpful later on.

Easy to use

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.

This works pretty well for identifying breakers on a circuit. In my case, I had to put the sensitivity at the lowest level and as others have reported, you have to hold the wand in a verical fashion. Having the GFCI / circuit tester is icing on the cake. My second Uni-T product, both well made. I only wish this unit used double or triple-A batteries instead of a 9v battery. Still a 5-Star item.

It works like a charm

Fairly easy to use, plug in the transmitter in the test socket and move the detector over the breakers along a line down the breaker array on the side closest to the panel box wall and not near the panel center line . instructions say to turn the sensitivity all the way down eliminate cross-talk issue but I found a midpoint setting worked better. I would typically start at full sensitivity, sweep the panel to ensure it saw a signal, then step down the sensitivity until only one breaker trigger a response. Note I generally could not distinguish between the a/b breakers in a double gang setup. I did have one issue; the transmitter makes an assessment of the socket and can identify problems with the wiring. This worked initially, but after testing several sockets it consistently indicated an unconnected ground even on circuits it initially said were ok. I verified a good ground with multimeter so bad transmitter. I returned the unit and amazon promptly replaced it . havent had any issues since then.

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

Skipped the breaker that I knew it was plugged into

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.
