Klein Tools Circuit Analyzer & Circuit Breaker Finder & Wire Tracer Kit, RT390, ET450, 69411

This tool allows me to quickly test my outlets and AFCI and GFCI breakers performance in my home without using a meter. It does the job for what I need it to do.

I used this to test all of my house outlets. I found one that had reversed wiring, so it was definitely worth it. I was also able to independently test the GFCI outlet functions, and not just rely on the test buttons built into those outlets. I don't have any AFCI outlets so I can't try that test function.Tester is easy to handle and small enough to reach most outlets. Cord length is short but acceptable given the function of this tester. An extension cord may be needed for reaching outlets where there is not enough space to fit the tester, or where the tester display needs to be located far from the outlet for easier viewing of the status lights.The build quality is good. The tester display just has simple lights but they are easy to see and understand.The main downside is that the tester turns itself off too quickly. This frequently happened right when I plug it into an outlet. According to the instructions, the tester shouldn't be turned on while it is plugged into an outlet, so it's a little annoying and a slight waste of time every time it turns off to pull it back out, turn it on, and then push it back into an outlet. It would be great if there was a way to adjust the amount of time it can be idle before it turns itself off.

After, having another options, this Became the most important tool for my electrical projects .Reliable, Consistence … just one down side, is turns off, a little faster than, for me Coming and Going (in a Second Floor) working alone !And, Having- have been Made , outside of the States .

Overall a good tester for commercial use. Screen is bright and easy to read / photo. My only complaint is it does not show the hertz. Being that i use it on yachts, knowing the frequency output from the generator is needed.

Got this to replace an Amprobe that I apparently left on a jobsite (ouch!). Had that Amprobe for a very long time - checked on getting another - they now cost considerably more! This is smaller than the Amprobe, and actually a bit easier to use - displays 3 loads with the push of a button - instead of pushing 3 buttons. This circuit analyzer has a very nice, easy to read display. Have not had it cut off on overheat - yet - and I use it a lot.

If you do electrical work a Good tool.to have

Excellent find I have been using it a lot and gives me the information I need

GFCI only testers are pretty cheap: just get the plug on kind with plain incandescent bulbs that show you bad wiring combos and have a "GFCI" test button. Those do fine. I got this for the AFCI testing ability, and I am impressed with it.I assumed that the tester "cheats" by synthesizing some kind of voltage signal on the wire that tricks the breaker into tripping, but this device has a component inside that generates an actual electrical arc. (There is a teardown video on YouTube that is great). If the breaker doesn't trip (e.g. you use it on an unprotected circuit) the arc will go on for a bit and heat up the component. The device has a temperature safety built in that will show you the arc generator is too hot and won't let you trigger it. This is a quality tool.Now, I did say for wiring state and GFCI the cheapo passive plug in ones are sufficient, but this tool also has a more comprehensive readout for the outlet state. For example, on one of my outlets, after the breaker tripped with the AFCI test, I got a read out saying something was wrong with the off state of the outlet. I have to now check to see what happened.

Easy to use and works very well. As an electrical contractor, I find this tool invaluable for assessing GFCI & AFCI function. The circuit load test feature is also a very convenient and valuable tool.Quite a good price for the work that it is capable of accomplishing, in my opinion. Next level of development could be the ability to log and archive test results.

Lo único vamos del producto es que las baterías se dañan muy rápido, hablo que una semana después de ponerlas se vaciaron :( así que recomiendo quitarlas cada que no lo usen o ponerle desde el principio unas de buena calidad

Love the fact it does voltage drop test

Bpn

I like that is has two AFCI settings. Also the flexible cord allows you to use it in tight spaces.
