Questions & Answers

Does this work on dead circuits

Asked by: Skip
No. It can only identify a breaker if that circuit is energized. The transmitter plugs into a powered outlet and sends a signal to the receiver(the tool you scan the breaker box with). If the power is of the transmitter can't transmit as it's powered by a closed, energized circuit.

Will it work on dead lines

Asked by: Smash
No, this unit will not work on dead lines. The transmitter needs to be powered by the outlet in order to communicate with the receiver.

Will this work with fuses?

Asked by: Billy
Probably. You plug in an RF generator into the line of interest and the wire broadcasts RF.

Works well for unmarked or mis-marked panels, may not pin point the right breaker but it gets you within one or two breakers. I keep this in my tool bag and have used it a few times. I use the gfci tester more than anything. I wish it also had an afci tester, and ncvd in the receiver tip.

Rated 5 out of 5 by from I like it a lot. Great product.Yes you can get signal from other Breakers.I do suggest buying the accessory kit for the other plug accessories.The nice thing is if you miss the breaker and you still have the transmitter plugged in, and you will see the lights on on the transmitter knowing that that circuit is still on.I have used this more than once and I do like it. It does reduce the flipping this breaker and that breaker on Etc. Isolates it to the one or just a small amount that you can figure out.

Rated 5 out of 5 by from Great product Recently moved into a new house wirh a completely unlabeled panel. Had to run some speaker wire in-wall today and wanted to make sure I killed the power in the wall first. This tool was great and easy to use and i quixklu located the right breaker to flip. Also tests GFCI outlets. If you have an older house, be aware the transmitter requires a 3 prong outlet and youll need an adapter. Overall - great product!

I like the dual function of the transmitter, and very conveniently attaches together for easy storage, this combo has allowed me to eliminate one more tool in my bag. I sell Klein tools at the home depot, This is one tool I highly suggest for both DIY customers as well as PROs., along with a multi-meter.

The Klein Tools Digital Circuit Breaker FINDER has been a tool that I have needed for a long time to some personal Electrical Projects.
