Klein Tools 80016 Circuit Breaker Finder Tool Kit with Accessories

This is honestly a fantastic tool, and I couldn’t be more impressed with its performance. One of the standout moments for me was when I was trying to locate an unknown breaker in a breaker panel—something that can be a real hassle, especially if you don't have the right tools. This tool made the process so much quicker and easier. What would’ve been a guessing game or a time-consuming trial-and-error process turned into something almost effortless. Not only did it help me find the correct breaker without any headache, but it also made me look like I actually knew what I was doing—always a plus when you're trying to impress friends, family, or clients!I’ve only scratched the surface in terms of using all the tool’s functions, but even just using it for this one task, it paid for itself. Honestly, after that experience, I knew I’d gotten my money’s worth. The fact that it saved me so much time and frustration made it a solid investment right from the get-go. It’s one of those tools that you don’t realize how much you need until you use it—and then you wonder how you ever managed without it.While I’d highly recommend this tool to DIYers—especially if you’re someone who enjoys working on electrical projects or home repairs—it’s definitely versatile enough to be useful for professionals as well. Whether you’re just dabbling in home improvement or you’re a seasoned expert, this tool offers enough reliability and functionality to make it a handy addition to anyone’s toolbox.In short, if you’re on the fence about it, don’t be. Even if you just need it for a single task (like I did), you’ll quickly see that it’s worth the investment. Plus, it’ll definitely make you look a lot more competent than you might feel in the moment—always a nice bonus!

Whether you just want to check an outlet, or a panel switch, or if you want to map every outlet/light fixture in your home (because you probably won't find it in the breaker panel cover sheet), this tool set is fantastic! It saved me a lot of time without having to flip breaker switches on and off while running all over the house to check which outlet/light/appliance was on which circuit. Anyway, highly recommend.

This Klein Tools circuit breaker finder kit is excellent. It's easy to use, it saves a ton of time especially if you're dealing with a big house where the breaker boxes look like pots of spaghetti and have no readable labels, and it's compact in the case, making it a snap to bring pretty much anywhere. Absolutely a worth it item.

Love this product, sure is a time saver. Not sure how I got by without using it al these years. Definitely worth every penny.

This is a very nice tool. It works well, per the printed / included instruction manual. (I REALLY like that a printed manual is included and that it fits inside the hard zipper case). The manual is printed in English, Spanish and French. I really like the case, w/ a fitted cavity for all the parts.This tool is (mostly) complete. It doesn't include a #1 Phillips screwdriver, required to open / close the battery door. It is nice that the small battery door screw is captive. It is nice that a (Chinese) 9V battery is included.The illuminated NEMA 5-15 plug-in sender has three indicator lamps, w/ result chart label, for standard wall receptacle testing. It also has a pushbutton to short Neutral to Ground for GFI breaker disable testing. It also automatically transmits the signal to the circuit breaker panel for identification testing.The kit includes three adapters for increased versatility. There is a Edison E26 screw to polarized NEMA 1-15 receptacle adapter for testing standard screw-in light bulb sockets. There is a NEMA 5-15 receptacle to polarized NEMA 1-15 plug, w/ ground screw tab, for testing w/ light bulb adapter. There is a dual insulated alligator clip to NEMA 5-15 receptacle for testing dangling wires.A BIG improvement suggestion is to change the product, from tolerating 90-135 VAC, to instead tolerating 240 VACThe receiver / detector has a NEMA 5-15 receptacle, to store the transmitter between uses. On my device the insertion / removal force was greater than I think is appropriate.The device always exactly located the correct breaker in each of the tests I performed, following the printed instructions.This is recommended.

Once you learn how to really use it. Makes finding power to an outlet easy and locating circuit breakers as well.

I picked this up primarily for projects around the house like replacing outlets and doing minor electrical work, and it has performed exactly as expected. The breaker finder makes it quick and easy to identify the correct circuit without the usual trial and error of flipping breakers back and forth. It consistently detected the right breaker during my testing, which saves a lot of time and frustration.One unexpected bonus was the included bulb socket to outlet adapter. I actually used it while traveling when a condo balcony didn’t have an accessible outlet, and it ended up being incredibly useful. That kind of versatility makes this kit more valuable than it might seem at first glance.Build quality is what I expect from Klein — solid, durable, and dependable. Klein has always been one of my go-to brands for electrical tools, and this kit reinforces that reputation. Everything feels well made and designed for real-world use rather than occasional DIY novelty.The tool is straightforward to operate with no learning curve, and it’s compact enough that I’ve added it to my everyday carry tool kit for home maintenance.Honestly, I don’t have any negatives to call out. If you do electrical work around the home even occasionally, this is one of those tools that quickly pays for itself in convenience.

This kit makes it much easier to identify the correct circuit breaker without repeatedly walking back and forth to the panel. The transmitter and receiver are simple to use, and the breaker finder has been accurate in normal residential and light commercial work. The included outlet tester and accessories make the set even more useful for troubleshooting.It is a practical, well-built kit that saves time and takes the guesswork out of circuit identification.

It works really well and I was a little hesitant testing a 125vac 20a circuit just using the clips I thought perhaps because there was not ground the sensor may not like that but it worked extremely well and I locate the " unmarked" breaker within minutes. Thank-you
