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

Great tool for electrical work when you need to chase down circuits and be able to find the right breakers sometimes it’s a bit off but I believe it’s due to how the wiring is setup in the beginning

I had a little breaker-mapping project. This tool is not a requirement for that, but it certainly makes it a lot faster and easier to get the job done.

Seriously, this is a life saver. We just purchased a home built in 1923 it has been remodeled many times. Leaving us with odd outlets and switches. This has been a life saver literally and time saver figuring out our wiring.

Great purchase and easy to use instructions were easy to follow. I use the item in multiple homes and also provided training to others on how to use.

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.

I have used the one i purchased on many occasions since purchased. It has been accurate every time with reliability I do recommend this to anyone who needs to trace a wire.

The best. Great videos on YouTube

Amazing trouble shooting tool
