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

This thing identifies an outlet on the other side of the house that is not noted on the breaker box legend.

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

My boss uses this all the time and it gets the job done. So had to order me one and I cannot complain.

I haven’t got it to work on my home sub panel but it works on my main.

Followed the directions, and it worked as intended. I located a circuit breaker and tested a GFCI. Not much else to say. For the record, I also got the Klein 69401 case and this will fit, as long as you dont leave the transmitter attached to the receiver. Note that the accessory kit 69411 also fits in that case with the ET310 as well.

It was frustrating guess which circuit breaker an outlet was connected. With this the guess work is eliminated saving time and effort.

Ive had another brand of breaker finder in the past which ended up not working after a few years. This one is by far superior in both accuracy and speed, there is no guessing as to which breaker is the one youre looking for.

Great quality and ease of use. Helped us find and trace breakers accurately on exterior.

This is pretty easy to use. You plug the transmitter into a live electrical outlet, then you use the wand to find the corresponding circuit. If you have tandem circuit breakers, its a little more difficult to determine which breaker is the correct one. It helps to make contact with the tip of the wand, and make a few slow passes. You can also detect which other outlets are on the same circuit as the outlet you plugged the transmitter into, but that is less reliable, though useful. It functions as intended, and the accuracy is high enough to do the job. Five stars. I keep buying more Klein tools, and Ive yet to be disappointed by the quality, functionality, or price. This set is quality, just like everything else Ive purchased from Klein. I do recommend that you buy the circuit breaker accessories kit (69411). It includes some extras which include a light socket adapter (E26 base), and an adapter with alligator clamps for bare wires.

The circuit breaker that would show red on was eight circuits away… it was not even close and not even in the same row. Worthless don’t waste your time or money.
