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

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

Works as described

while nowhere near as good as the more expensive pro-level ones, this one works well enough to map out the mystery fuse box in the basement. Mine had just a couple labels- and even those were wrong. Now I can swap outlets and lights without having to take out the power on the whole house. The build quality is light and it wont take abuse like a pro tool- but its amazingly inexpensive and works.

Could not adjust to work on any breakers, junk

This tool will not accurately detect a breaker at any sensitivity

Would like a version of this with a lightbulb type socket so I could trace all my in ceiling can lights as well, since the builder of my house didnt do so well marking EVERYTHING on the circuit panel in the baesment, so its always been a wild guess, if hitting the breaker for, say, the second bedroom will get the outlets in the hall outside as well or not. This at least lets me track more than I was able to before. So far weve had no issues. Its one time where having a son is convenient, since I can have him go room to room and outlet to outlet while I draw things out and track them in the basement.

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.

We just moved into a new home, but discovered the electrical panel was poorly labeled. This tool helped us map all the wall sockets to their appropriate breakers, so we can power down only the outlet we need without affecting others. This is an extremely useful tool to have around.

Got my Item very fast and in good condition. I would buy this again.

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.
