Klein Tools ET310 AC Circuit Breaker Finder, Electric and Voltage Tester with Integrated GFCI Outlet Tester

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.

Voltage detection:Works great

I'm not an electrician, but I have to play one in my house. Electricians $$. I also live in a 1940s home, remodeled more than once before and since myself. That means mysterious electric wiring all over. So I needed this badly. Klein is one of the quality devices in line testing, and this one is up to par. It accurately reveals where a outlet leads to which circuit at your electric panel.works well, and accurately almost too sensitive so check nearby circuits several times and settle on the one by flipping that switch and then the outlet then without power. It looks a bit long, but that's because the two parts are meant to when not used. I.e., you don't lose one part.

I bought this product because I really need it at work. I saw it on Amazon and bought it. It really works very well and does its job.

Excellent tester to make sure you find the right breaker for the outlet you are working on. Then test to make sure that you have no power to the outlet once you turn the breaker off.
