Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories, 2-Piece Set, Includes Cat. No. ET310 and Cat. No. 69411

Why did you pick this product vs others?:This one of my favorite tools! I especially like that it has various connectors for multiple devices (receptacle , bulb socket, direct to wires, etc.). It was always a pain working on my or my kids houses because the electrical panels were not fully marked. So, I would end up shutting down a lot of circuits I didn’t need to, which required resetting clocks, etc. on a bunch of devices. Works great.

Saves me a lot of time in looking for the right breaker . I used to plug in a radio and hit an educated breaker but now . Plug the sensor in and use the tracer and BAM you found the breaker .

I’ve only used it to check a couple of circuits, but so far it performs as claimed. It is very important to follow the directions for scanning the breaker panel first. A very handy tool to have.

Works great! Excellent safety tool! I bought the accessory case for storage. Should have bought this at the beginning of my electrical career. A must have. It’s an excellent tool for weekend warriors doing projects.

Saves a lot of time tracking down the breaker that serves a specific electrical load. Takes some skill to use it well, and it still may give false positives, forcing you to still need to turn off a breaker to see what loads are de-energized. Basic operation is tracing from electrical outlets. Biggest problem I've had it that there is no good/easy way to trace from a wall switch or from a hardwired load. This is partly because it wants to connect to both line and neutral. There is an adapter for medium base ("standard") light sockets, but not for other sizes or fluorescents. So it does what it does, but it is not (and cannot be) the 100% solution to tracing. Why I deleted 1 star.

Such a useful tool for an old house with a terribly labeled breaker box. Directions are easy to follow and the tool is built very well. Nobody likes getting shocked and I haven't been ever since I purchased this tool.

Received this today and had to play with it right away. Tested a few circuits in my home and this was spot on. Would recommend.

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!
