80016 Circuit Breaker Finder Tool Kit & RT250 GFCI Outlet Tester & NCVT3P Dual Range Non Contact Voltage Tester, 12-1000V AC Pen, Flashlight, Audible and Flashing LED Alarms, Pocket Clip

An easy to use kit, this Klein gizmo won't disappoint. It helped me map out two circuit breaker boxes and their respective house outlets in two different houses very quickly and accurately. At a decent price, indispensable. Now if people I loan it to will get their own and give me mine back... 😄

This circuit breaker finder was super easy to use and worked exactly as expected. My husband was especially happy with how quickly it helped him identify the right breakers; no more guesswork! Great tool to have on hand for any homeowner.

It works as it's supposed to, and the sensitivity narrows after initial scanning. On my Cutler Hammer CH panels it works better if the front cover is off the panel, but it's apparently not so great across the breaker fronts themselves. I just bought it so there may be a learning curve for me, but other reviewers have noted the same thing with CH breakers.Also works for identifying wires on the same circuit in different boxes, not just the breakers themselves. With an old house and electrical many revisions over the years, conduit running everywhere, this is what I really needed.Surprise addition is that the transmitter that you plug in is also a receptacle polarity and ground tester and a GFI tester. I bought the model that came with the accessory pack that includes an adapter for Edison-base light bulb sockets, a 2-prong adapter for non-grounded receptacles (and needed with the light bulb adapter), and an adapter to connect the transmitter to wires, etc rather than plugging it into a receptacle. None of that is crucial, but it was a cheap add-on and wil be handy on occasion.I've had a cheap circuit identifier for years, the blue one sold under many names, but it's never worked well. The only thing that does reliably is turn on and beep whenever it's touched or jostled (no positive off switch). Not sure how many times it actually identified anythiing, except identifying me as a fool for buying it. And it wasn't really that much cheaper than this quality Klein tool.I've always been satisfied with every Klein tool I've ever bought, this one included. No doubt there are more exotic circuit tracers for specialty applications, but this works as advertised for simple 120 VAC wiring.

Fantastic tool for electrical work. I've used to ring out all my plugs and lights to make sure my breaker box labels are correct and up to date. Definitely needed for old work!
