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

When searching for a circuit you may find that the wires run next to each other coming into you circuit box. This means the device will read for multiple breakers. Just scan the breakers until you receive the strongest signal.

Works well. Itll help you out and cut time off of finding circuits.

As an electrician I use it a few times a month to identify circuits I plan on working on. It hasn’t dIls me yet.

You need to touch the sensor to the wire and not thr breaker, but if you do it works like a charm.

Not worth its weight. Unable to locate a single breaker at four different locations. The plug analyzer / tester works great though.

So helpful with my unlaced breaker box. The adapters to allow to find lights are amazing as the lights are sometimes on different breakers that the outlets. Definitely worth the money and works as expended just like every other Klein tool I’ve owned.

Works great for labeling sub panels

The first time that I used it I was able to find and correct a faulty recepticle and save a $180 electrician bill. A definite need for any homeowner / DIYer

Stop working after three weeks. Changed the battery and everything, never turned back on.
