Klein Tools ET310 AC Circuit Breaker Finder, Electric Tester With Integrated GFCI Outlet Tester

its not working

Works great!

To locate faulty breakers to be replaced. Q

This works AMAZING!!!!

This tool quickly identified the circuits for the outlets I was working with. Much easier than plugging in a lamp and selecting a hopeful circuit at the panel, walking back to check the lamp and trying again. If you know, you know. Simply gets it right the first time. Also does the expected of letting me know if my main and neutral wires are correctly connected and Im properly grounded.

I used it this weekend to trace down circuits in my home. It worked as expected and was very easy to use and understand.

I have used this device extensively and I have found that it works extraordinarily well on newer wiring (Romex). I bought this tester in December of 2019 and its worked great since that time. I use it weekly and once you get a feel for it, the tester works well. You have to be a lunkhead not to get this work. My home was built in 1992 and over time, the cheap, builder grade switches and outlets have begun to fail. Ive changed the old ones out with new Lutron versions. Ive found that about 50% of the labels on my panels box were wrong or incomplete. This tester has made the process of locating the proper breakers and swapping out the old/new switches and outlets foolproof and simple. It allows me to properly label my panel box as well. The full kit contains the following (case is extra): - Probe - Transmitter - GFCI tester - 3 prong to 2 prong plug converter - Light bulb connection - Bare wire connector - case is extra - multiple versions are available on Amazon Pro: -Simple to use. Plug the tester into the desired circuit outlet or bulb (adapter for bulbs included), it lights up to show power to the circuit and has a GFCI tester as well. Power up the location wand and slowly move it over the breakers and it glows and beeps continuously. -You get a sense for when you are on the right circuit with experience and the wand lets you know. Yes, if you hold the wand over the main power breaker, it will tell you its powered breaker because technically it is - but youll turn off the entire house with that breaker. -Small, lightweight, reasonably priced, the full kit is versatile Con: -I have not used this tester on old knob and tube two wire circuits - they may present an issue but Im not sure. - Case is extra - it needs a case for the larger kit Overall, this is terrific circuit locator/tester. I just used it prior to writing this review to locate a 20-amp garage outlet circuit with a GFCI that was labeled appliance on the panel box. Electricians..... I have NO idea why some professional electricians are so lazy about properly marking circuits - use a label maker and do it right. Im not a licensed electrician but I know lazy when I see it. Hope that helps! From my experience, this is a great acquisition. Hope that helps.

Worked like it was supposed to four outlets and finding the switch in the panel.

Ive got an old house that has a combination of standard 3-wire wiring, but also has some old school 2-wire wiring (no ground) on the floors where its too painful to re-wire. Ive slowly been going through and replacing the 2-wire outlets with GFCI outlets (which Im allowed to do code-wise in my state). While I dont technically need to replace all of them, I want to stop using the 3 -> 2 plugs everywhere. Also, the GFCI outlets are tamper resistant, and the old outlets are not. This breaker finder has been really helpful. My house has 4 floors, counting the basement. I have 36 poorly labeled circuit breakers (except for central A/C and clothes dryer) That being said, this was a bit tricky to use at first. Until it was calibrated, I got a ton of false alarms. Now that I have it setup correctly, Its no longer giving me false results. This has saved me a ton of time, running up and down the stairs. I suggest going very slow when calibrating; If your results dont seem right, reset and try again. I calibrated the unit 3 times, and its been smooth sailing since then. After I finish replacing the outlets (I do this when no one else is home, so its a very slow process), I plan to use this to build a map of outlet -> circuit breaker. Some of my rooms are wired to multiple breakers, which is quite confusing - Ive learned to careful test every outlet and not assume that the power is off to the whole room.
