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

PLUG IN ATTACHES TO THE END OF PROBE WHICH IS A NICE FEATURE the probe works as well as I expect, it gets to the breaker and beeps faster than the ones next to it, flip the breaker off sound stops,and done

I have a 1950s era house. For my house, this product cannot successfully locate the correct breaker. The wiring is not knob and tube, but a varnished cloth insulated, 2-wire (no ground). When I plug in the transmitter, I can pick up the signal near the transmitter itself. ...so the transmitter is putting out something. Back at the breaker panel, I reset the receiver (probe), went though the probes learning process, then tried to sense/measure. There were some random beeps, that youre told to ignore during the learning step. I scanned the second time, aaaaaand nothing. Ive watched videos where many people get good results. I matched, scan rate, learning step, probe angle, speed, etc. and it just doesnt work on my house wiring at all. The fact is, I already know what breaker I need to open, but I just wanted to see the tool be able to pick it up. I tried many times as objectively as possible, trying not to favor the known breaker. I tried different areas of the breakers, trying to find the largest field that could couple into the probe tip. Nothing improved. There may be too much noise on the line etc., but it doesnt work on every panel, or situation. People that say, youre just not using it correctly, might not be aware of all of the things that could make this not work.

I use this a couple times a week in my work, and Im quite pleased with it. When someone walks off with it, Ill buy another. Seems accurate to me, I use it in some pretty large houses and it seems to get the signal well. Occasionally, ts slightly ambiguous as to which breaker. Probably user error really. I think it works great and Im pretty OCD finicky. And yeah, get the 9 dollar add on kit for open/bare wires and light bulb sockets. It probably should come with that. But ehh. I suppose the only gripe for me is the GFCI test indicator lights are a bit dull on the GFCI tester part and bright sunlight seems to mess with that. Others I have are well lit crisp and bright. With LEDs these days, youd think there would be not much reason for that, that I know of.... But they may actually have some reason behind using what seems to be an ancient orange light bulb of sorts. Dunno... Oh... And... Its not a Swiss army knife. Its a circuit breaker detector... For dead circuits, I use my trusty Fluke signal generator. If I want to find hot wires in a wall, I use a stud detector I have that does metal pipes and wires as well. Or, a Sperry adjustable non contact tester, that can be adjusted quite sensitive and wind wires in a wall VERY well. If I want to get intimate with e GFCI, I get my Fluke meter out. If I want to test an Arc Fault breaker, I guess Ill fork the dough over for a a Klein RT310 AFCI tester...

First one I used a signal trace. Works well. Need to proceed slow to be most accurate. But you can isolate what breaker is connected to the outlet

Better than flipping breakers

Works sometimes

Bueno

This will only trace live circuits. It does not generate a tone to trace inactive circuits.

Work better than my expectations!!!

ok
