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.

I have several UNI-T instruments and I have found them to be well made and less expensive than bigger name brands. The circuit tester function of the device works well and is clear to read and understand thanks to the onboard labeling showing what the light combinations mean. The GFCI tester worked perfectly. The circuit breaker locator function takes a little more effort to learn to use effectively, but I quickly found a way to make it consistently locate the correct breaker. When I started using the locator probe I found that it would trigger prematurely if I touched the white part to the circuit breakers. Typically more than one circuit breaker would trigger the locator tone as I got close to the correct breaker and I couldnt adjust the sensitivity to prevent that (either there would be no detection or multiple detections). Remembering something I discovered with my underground wire tracer, I lifted the probe off the circuit breaker by about 1/4 to 1/2 and then scanned for the correct breaker. This resulted in perfectly reliable operation. That may be something specific to my brand of circuit breakers or the length of the wire runs in my home, but if you struggle with getting an accurate reading, give it a try and see if this is a helpful tip for you too.

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.

Es perfecto para localizar los breaker en el panel haciendo facil todo el proceso y descartar pocibles errores acelerando la solucion.

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

I own lots of these, and I am always ringing out wires... if you read bad reviews, well, that will happen with these products... mainly because, they are very unique, tempermental, and each brand has its own personality. for the newb, it can seem like, its too hard to trace, but with some trial n errror, u learn what works. how? test on a circuit you know both ends... be sure to pick one in the middle of the breaker panel find a way to test, so it works, adj. sensitivity, distance, speed, etc. once you perfect one that works, u can then move on to the mystery circuits... overall, for the receptacle gfi tester, and the tracer, this is an amazing value, and it works! recommended! 4.5 stars

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

It works like a charm

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.
