This is a must have kit for multimeters, clamp meters & Circuit Breaker Finders. All the items in this kit are well made even the 2 to 3 prong adapter and screw base adapter are much better made than the usual ones offered in stores. I like that the female strain relief actually shows where the red & black wires terminate to, the larger or smaller spade (see pic). I have other Klein products and they have never let me down. So do yourself a favor and step up to this well made set at a very reasonable price. If you found this review helpful please click on the thumbs up, thanks MikeTheReviewer
I had a series of outlets and some unused switches that need to be removed or renewed. I used this on the switches to determine the correct breaker to turn off. This breaker was in a large panel of thin series 2 pole 110 breakers along with a few 220 V breakers. Hooked up the test leads plugged in the transmitter scanned the panel and first time found the breaker. On another attempt possible my fault I was mistaken by one breaker on the thin series 110 V. I think I was not careful enough to allow the breaker finder to beep on the correct half of the breaker. I wish that I bought this years ago. Small price to pay for the quick results in finding the correct breaker. As stated in prior comments, go slowly over the panel of breakers. I also a time or two turned off then back on the sensor to double check myself. My panel was in a back room maybe 60 feet from the switch/outlets.
