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

Since I’m not a certified electrician this device has allowed me to trace which outlets correspond to the the correct breaker. It comes with instructions and we also have access to YouTube. This is a great purchase for homeowner diy or an electrician.

Worked exactly as expected. I am a novice for something like this tool and it was easy. Answered many questions that were long overdue.

Dont own this particular device although have many Klein tools. By definition these arent foolproof, many sources of error/ambiguity. Before considering spending for this, go to your breaker box and spend the time to make a map of all your breakers and what is affected on the circuits. You wont regret it. After an early experience Ive done with with most every house. Its a time waste, but its not a time waste, will save you from headaches. The accuracy score is indicative of devices, not this one.

Problems down line can give some false readings

Very easy to use line test and find lines, but the only regret is that there is no tool box, I need to buy extra

Works like a charm! Moved into a house and all the electric panel had general lighting down 11 CB. No idea what CB went to what. But now I have an idea. Yay

Great tool. Able to locate switch that’s not labeled in an older house

This made expanding my circuit breaker index so much larger. Also helped me determine that I have a few gfi’s going bad. Wow! What a great product! Fun and easy to use. THANKS SO MUCH FOR MAKING MY LIFE BETTER!

Needs a working circuit. I need a tool to find the breaker that is not working.

Used it a couple times so far works pretty good For the price.
