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

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

Ive used a handful of these style circuit breaker finders, and they never work 100%, but they always help to narrow it down to 1 or 2. That alone can save me a lot of time. This one is no exception. Its important to remember to slowly scan all the breakers at least once before diagnosing. It has a sensitivity adjustment. I started it out on max, and it showed most of the breakers as positive. I turned it down about half way, and it showed 2 breakers that were next to each other. The first one I tried was the correct breaker. I also like that it comes with a wiring checker and gfci tester. If you dont already have one of those, this becomes a very handy set. Overall a great tool. Highly recommended.

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.

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

Easy to use

El producto es muy complicado y no es certero al usar e encontrar el breaker

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.

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.

The purpose for getting this device was so that I won’t have to flip all my circuit breaker switches off to find the right one. This did not work for me. I read the instructions, watched YouTube, read Amazon reviews for tips, adjusted sensitivity, the position and the distance of the toner - all of which did not help. It identified multiple, and the ones identified were not the right circuits! At one point, the toner made noise in two completely separate electrical panels while probing! (Mind blown!) I plugged in the transmitter to different receptacles, and in different rooms. Lastly, I took it to a friends house for him to try. He knows a lot about electricity and he did not spend as much time as I did with it before he determined that the device doesn’t work. We have conclude that this thing doesn’t work on U.S. homes built on or after year 2004. I was very hopeful and excited when I ordered the device - ended up disappointed.

I ordered this to add to my electricians toolkit. Ive been to houses before to diagnose electrical problems. It can be frustrating when the circuit breakers arent marked inside the panel. So I thought this would come in quite handy. One of those tools you dont use often, but when you need it, it pays for itself. So I tried it out the other day. The outlet had no power. Using the tester, I was able to locate the circuit and it had a GFCI in the panel. I tried the transmitters GFCI test on a couple outlets in our house. The test worked perfectly. Next I tried the receiver paired with the transmitter to locate a breaker in the panel. The first try, I got nothing. I reread the instructions and then double checked the battery. I included a picture of the battery as shipped. I first glanced at it and thought all was good. The battery is shipped wrapped, inside the compartment, but its not connected. You will need to remove the battery, remove the wrapping and plug it in. After connecting the battery, the tester worked perfectly. I tried two outlets and was able to detect their breaker inside the panel. A great tool for identification purpose. The UNI-T transmitter is easy to read. The key is printed right on the tester for reference. I have a similar outlet tester with small LEDs on it. This UNI-T is much easier to see and read, glowing brightly. I tried it on multiple outlets, finding nothing wrong. The UNI-T AC circuit breaker tester and finder is a welcome addition to my toolkit. For the current price of $28, certainly a reasonable price for a tool sure to prove invaluable. Im happy with it and recommend it.
