Klein Tools ET310 AC Circuit Breaker Finder, Electric Tester With Integrated GFCI Outlet Tester

We purchased an older house and needed to check several things with the wiring per the inspection. This has worked like a charm and definitely is accurate. Read and Follow the directions and you wont have an issue. I highly recommend this tool.

My house was built in the 80s and has 200 amp service. For some reason this didnt work for me. Returned.

If you take the time to read the instructions, this thing is dead on. Saves a lot of time! Would definitely recommend.

Paid for itself the first day of use.

Tried it and it worked perfectly.

Wish I had this a long time ago. Such a help

Love it, works great. Master electrician approved

Not to impressed,, didnt really do what.I thought

Work great and accurate.

I received the breaker finder and was playing with it to learn its proper use. I would plug the transmitter into an outlet and try to find the breaker. Following the directions the receiver would signal a breaker. I would turn off the breaker but the transmitter would remain energized. It never did signal the correct breaker. I called Klein Tool and they told me that you must go around and unplug ALL of the surge protectors in your house in order to use this device. Supposedly the surge protector puts out a signal that interferes with the breaker finder signal.
