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

With the adapter accessories (sold separately), you can chase down which breaker controls the outdoor flood lights and coach lights. I wanted to add a photo cell so that those lights would come on a dusk and needed to see what breaker was controlling those lights. Very nice tools!

Easy to use.

Very nice tool

Tracing my plugs and lights to the breaker panel. What a time saver. Just a few misses, but I was able to label my breaker panel properly.

Excellent tool and easy to use.

The first time I used the product it worked fairly well... It wasnt clear which circuit... Seemed to be triggered near a group. The next time I tried it a couple months later it powered up fine, green light displays, and beeps at a steady pace ... But it never indicates the actual circuit... The beeping doesnt speed up even when I know which circuit is the right one, and testing and changing the battery made no difference. So I can see this as potentially a good tool, especially if your circuits arent marked well... But if course it would need to work in order to be useful.

Ive used another tester like this in the past, and it worked fine. The old one broke, so I bought this one. First off - I KNOW HOW TO USE IT. But it doesnt work for me at all. Even when I know which breaker it needs to find, it doesnt find it. Yes, I went through the breakers twice, and yes, I turned it on before approaching the panel. It always finds a breaker which is the wrong one. EVERY TIME. Very disappointed.

Love the brand

Wow, this saves me time. The accuracy is great, fast to use, and the ability to plug them together makes sure they do not get separated.
