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

I had never wanted to take the time to map out breaker assignments in my home, because of the time it would take to go room by room with someone yelling “NO or OFF” as I tested each breaker. This convenient little device makes it simple to do alone, and it’s done with the power on. Just plug the little transmitter into an outlet and then wave the receiver slowly across the row of breakers and it alerts you when you’re near the correct one. The transmitter even displays whether the outlet is wired properly hot/neutral/ground. Very convenient !

Great little product. Ran it through alot of tests and perform over all great. Little sensitive on showing the breaker above or across the actual circuit your looking. Make sure you have solid red before shutting off the breaker.

good

Recomendable

Great product does what it’s intended for

After installing the battery, its very simple to use. I recommend getting the accessory with the light bulb adapter, 2 prong adapter and clip-on adapter. I used it on a cell site tracing out power to equipment and cabinets. This tool the guess work out and the clip-on adapter allowed me to trace power all the way back to the power meter.

Is a very nice set. Very good quality.

When it arrived, I tested it on about 8 outlets throughout the house, and every time, the probe picked the same wrong breaker. Ok, no big deal, I might have a defective one, so I ordered a replacement, it did the exact same thing, so I thought, maybe my house is broke, Ill take it out on a job and try it. My first job, it picked up the master breaker for every outlet I tested. Next house, the results were the same as my first test. I finally had to admit defeat and request a refund. For those that it worked for, I really would like to know what conditions were different than mine.

Works perfectly

Works well but be careful if you have two lines in same outlet (split circuits) device will register at fuse box for both .. breakers
