Would it work to find the wire in the attic ? I want to plug it into an outlet, and then go to the attic to find that specific wire (among several) so that I can cut the wire and install a junction box there to add another outlet onto that same line

Yes, works on any circuit with a plug.

The only reason it doesn't get 5 stars is the switch on the receiver is way too sensitive and will turn on accidentally if you put it in your pocket, or tool belt, or tool box.

That's the best way to describe my experience with the Klein ET300. 1. The on/off switch is poorly designed. The slightest touch of the pushbutton turns the unit on with a "beep" and a "trilling" sound -- and any subsequent touch of the button produces a "beep" & "trill". Don't try carrying this in your pocket! 2. Usefulness has been marginal. When it works, it's great. Much more decisive than my old GB Circuit Tracker. However, it's worked on only 1 of 4 panels for me. 3. No storage provided for the transmitter dongle. (I have the same complaint with the GB unit.) Why the designers don't include a simple socket in the receiver for it to plug into, I don't understand.(See Extech and Sperry for the right way to do it.)

I do recommend purchasing the Klein Circuit Breaker Finder "Accessory Kit". The kit included a set of alligator clips so you can attach the plug-in "Transmitter" and then you can find the breaker which belongs to a loose live wire. I used my kit to find a hot wires location to the breaker box. The kit also comes with a screw in plug so you can find, for example a can light location to the breaker box. I had one location at a wall switch which had a unused live wire in the box and was able to find the breaker using using the transmitter/alligator clips in just a couple of minutes. Wish I had purchased this tool long ago. The only negative so far is the on and off switch on the receiver is very sensitive to touch with no positive on/off button. But I can live with that because it shuts off if not used so if it does come on in my bag .. no big deal for how much time it saved me already.

The Digital Circuit Breaker Finder did not indicate the correct circuit breaker on most of the circuits in my panel. When it did correctly indicate the correct circuit breaker it also indicated 1 or 2 other breakers at the same time. I still ended up having to turn breakers on and off one at a time to identify the correct one. Just like I did before I spent money for this instrument.

Best used with cover off the electrical panel. Plug in transmitter to outlet, holding receiver horizontally slowly scan top to bottom the wired side of ALL the breakers - ignoring all the beeping and lights. Then repeat and it will identify the correct breaker.

I bought this to replace an identical one (except it was orange) that I’ve had for several years, but which had quit working. It has worked well so far, a great time saver. I had hoped they would have fixed the power switch, which is very sensitive, and gets turned on every time the tool is bumped.

I have used this for finding breakers in the last two days in unmarked panels you have to let it learn the panel per the instructions and this takes a little more time.I wonder if it had a sensitivity adjustment if that would make it even faster? Overall good quality I would recommend to a friend.

Rated 3 out of 5 by from Works great It works great but the problem I find with a lot of tools now is they don't have on and off switches so when you put them in pocket of work bag or even your on pocket of clothing it automatically activated reason for the 3 stars a on and off button would be great to keep from draining batteries...
