KAIWEETS KT303P Leitungssucher

Super great tool to have. I bought because of a social media video, best purchase I have made in awhile. Handy to have, also makes a great gift for a handyman.

I'm often working in unfamiliar buildings where I need to find the right breaker. And, of course, they are never labeled. This tool is extremely easy to use, very accurate, and much less expensive than some brands of tools. It works perfectly.

Another winner for Kaiweets! Well made, long lasting and very important tool to have if you are doing ANY electrical work. The screen is really clear and back lit. The sticker pages where you can finally make sense of your breakers and what they power. I accidentally dropped it from about 4ft and it was fine. The case is really nice as well. The tools you'll find in this kit are incredibly useful and really make safety the main concern. Checking outlet receptacles is made very easy. I've had it on for quite a while and the battery seems unfazed. This will really speed up your projects. Considering the low price and everything it comes with I think this is a winner.

The kit had some pleasant surprises. The supplied AAA batteries are Duracell brand. There is an adapter that accepts the 5-15 plug sender to alligator clip ends so you can easily attach to open leads (energized) and back track to a panel. The foam case is rigid foam and provides a good level of protection as well as having plenty of room to hold all the parts. Some adhesive labels are included for your first identfication job. The non-contact voltage indicator works very nicely with a reasonable proximity alert without physical contact. The tracer allows you to follow the signal from a device to other devices on the circuit to the branch breaker to the correct leg of the main breaker. The audio and visual alerts are clear and unambiguous. You do not get the common ghost alerts floating across adjacent breakers, it is very spot-on accurate. The GFCI tester works simply and the sender probe has clear indicator lamps to show if a receptacle install is correctly wired/polarized. The tail port for carrying the sender on the reader is a great idea to make it easy to use and organize.

The KAIWEETS circuit breaker finder correctly found 3 circuit breakers, unlike a previous finder I tested that tended to point to one breaker above or below the correct one. KAIWEETS has you scan breakers twice, and on the second scan it made a solid tone only when over the correct breaker, though it may briefly beep or flash on other breakers, even far away ones. On half-breakers with two smaller switches in one slot it can be hard to tell which switch the tone is directing you to, but in my test case the tone started and stopped nearest the top switch, which was the correct switch.

I like that the tester has a flat tip which should be slit flat next to breaker switches so each scan is at the same distance and orientation for each breaker. I also like that it comes with adapters so you can plug the AC end of the tester into light bulb sockets, two-prong sockets, or even clip to bare AC wires. A zippered case is included to keep everything together.

The AC tester has lights that identify wiring faults including open ground/neutral/hot, hot and ground reversed, hot and neutral reversed, and hot on neutral with hot open. I didn't test any of these features.

The AC tester also has a GFCI TEST button meant to test the Ground Fault Circuit Interrupter feature of bathroom outlets. A Ground Fault means that electricity is flowing from the line wire (the shorter slot in the outlet) to the ground, which may mean someone is being electrocuted, and so the plug interrupts the circuit (cuts the flow of electricity). When GFCI TEST is pressed, the outlet should immediately turn off power to the tester (its lights will go out) and a Reset button on the outlet should pop out. Press the Reset button to restore power.

KAIWEETS has been selling on Amazon since at least 2020, mostly electrical test equipment with generally high ratings. They even have a web site.

Overall, I'm quite happy with this circuit finder from a reputable company. 5 stars.
