    • Valuable Tool for DIY Homeowner
Style: Circuit Breaker Finder
I ordered this tester because it seemed like something that I should have in my "tool arsenal". I tried it as soon as I got it so that I knew that it worked and so that I would know how to use it when I needed it. Circuit Breaker Finder - Worked like a charm! I plugged the "sending unit" into an outlet and then headed for the breaker panel. Using the tester I followed the directions and slowly passed it over all of the breakers once and then repeated it. As you get close to the right breaker - it will start to chirp a bit and when you are on it, you get the tone and the red light and the flashing green - can't miss it! I then flipped that breaker and went back to the outlet I was testing and it was the correct breaker. Sending Unit/Outlet Tester - This is handy in that it shows you if the outlet is wired property (and it was) and I like the GFCI tester function. I tested several of the outlets in my kitchen that should be on a GFCI circuit and when tested, did trip the GFCI outlet that was controlling them. Everything works, it was easy to use, and it makes testing and working on your home/farm wiring really easy. 5 Stars and I would buy it again for sure. ... show more

The test equipment works great. Makes it easy to locate the correct breaker and the sensor makes it real easy to tell if the line is energized or not. The only minor problem is the zipper bag was not included with my order as the description states.

    • Worth it
Style: Circuit Breaker Finder
I debated on getting just the plug detector, but i figured I'd spend some money and get the kit with breaker detector & accessories (no pouch/bag). I've used this for checking a main panel swap and it paid for itself in finding a single outlet that was wired wrong and causing a network switch to not operate: after restoring power, there was no wired internet due to the network switch getting bad voltage. I can't even imagine having to find that problem with just my volt meter. 100% worth the electrician-skill-game enhancer. The breaker detector was easy enough to use and helps I.D. circuits where labels have faded or just don't exist. It got the correct breaker, but there was a 'maybe' with the neighboring breaker, YET it made figuring out which breaker was for the dishwasher for a replacement job easy. Before using this, it would require some investigating, tracing wires where applicable, deducing which voltage breakers (220/110), and even then we would have to take guesses sometimes and just start tripping breakers till we found the right one (or short the end of the wires together to force a trip, I know REAL safe...). Now, worst case, is you have 2 breakers that need tripped for the 1 circuit you're working on. I'm not sure how it would work if the circuit is wired wrong, i.e. if neutral and hot are reversed, etc, but the instructions say that the circuit must be wired right in the first place for the detector to work... Works for electricians of course, but as an HVAC/Plumber tech, I find it highly valuable. I think DIY'ers and homeowners could benefit for the "pricey" gear and kit from a know name brand. ... show more

Style: Circuit Breaker Finder
The Klein Tools ET310 AC Circuit Breaker Finder is an exceptional tool for anyone working with electrical circuits. I recently used it to locate circuit breakers in my home, and it made the task incredibly simple and efficient. The device is lightweight, easy to handle, and features a clear, easy-to-read display. I was particularly impressed by how quickly it detected the correct circuit breaker, saving me time and effort. The integrated voltage tester adds extra convenience, allowing me to check for live wires without needing a separate tool. It has a good range and is responsive, giving accurate results for both breakers and voltage. The design is user-friendly, with clear instructions that make it easy for even beginners to use. The compact size also means it’s portable and can be stored without taking up much space. For both DIY enthusiasts and professionals, this tool is a must-have for diagnosing and troubleshooting electrical issues. I highly recommend the Klein Tools ET310 for anyone looking for a reliable, easy-to-use circuit breaker finder and voltage tester. ... show more

Great value. This just works. Saves lots of time tracing a circuit you need to shut off with an unmarked circuit breaker panel.
