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

Great price

Another Satisfied Customer!

Had a few bathroom light switches i was switching. The lightbulb adaptor and the whole kit worked perfectly. It orked as advertized. Ran the tool over the breakers, got green. Ran it the second time as instructed and the same breaker lit up. It saved me quite a headache in changing that switch.

Made it easy to mark all my outlets with the # of the circuit breaker its on

Will only work if you are in close proximity of the service. Big disappointment.

This product really saves a **lot** of time, and is far better than the old school way that requires two people communicating, or worse, if alone having to go back and forth after each breaker is switched. However, mine would sound off within a couple of breaker switches of the actual switch targeted. It was difficult to ascertain which of, say, two or three switches was the correct one. The answer was to trip two breakers at once and I usually got it right. Regardless, it did allow me to conduct the work alone as well as saving a lot of time.

Accuracy only 5%

Easy to use

I was installing a power monitoring system in my main breaker panel and realized I was not sure which breakers some of my sockets were attached to. The ET3 rapidly and simply answered all those questions and I now know exactly what is using power in my house.

Like ease of use. Needed to identify circuit breakers to do some wiring.
