AFCI Breaker Testing 

Why???? No need, we, as electricians, need to band together and attack electrical companies poor maintenance over the years. They give us power, great, but how old are the wires and the poles that supply really are? The electrical industry needs to start questioning the the suppliers on this.

@@duanelohr1869 lol, that's a good one...

digitalcurrents Just down stream from the outlet.

Mozif This tester is very durable. It is built well, and has a high drop rating. I have tested hundreds of outlets with it, and it works great. I did blow a fuse in it one time, when I was stressing it very hard. But, the fuse is replaceable, and was easy. My original plan for this video was to feature both this tester, and the Amprobe INSP-3. But, the Amprobe did not work on all the breakers, and it actually failed on the 5th test. That is a $350 tester, compared to this $50 one, and this one works better, in my opinion.

@@MultiMeterChannel thank you very much. I'll also have to show this to my inspector.

An AFCI breaker will trip when the current exceeds the rating of the breaker, or on a short circuit, like a “standard” breaker does. But, it also trips when arcing is detected, like when a frayed wire is arcing and creating sparks between the hot wire and the ground or neutral wire.

Well, my plan WAS to do a comparison. But, the very first test I did with the Amprobe, it failed with an internal fault. So, rather than do the comparison, I just tested the Klein.

Justin T I got a new Amprobe, and did a video testing it against the Klein. It did not do well.

Yes, this generates a parallel arc. It is almost impossible to simulate a series arc that will work on all models of breakers.

I have never seen one. That would be almost impossible to tell for sure, and would just be a guess, so why bother?

This instance could provide an unbalanced load on a shared neutral multi wire circuit, which could place a voltage on the plugged in item’s chasis. That would be bad.

@Nik Kingman I know that it's over price, my question is if it's ok to install all AFCI in all outlets in the apartment?

Only if is a GFCI breaker. It will not trip a standard breaker.

MultiMeter Channel thanks

You would have to create an overcurrent condition, I.e.: direct short to ground/neutral. I have heard Breaker manufacturer’s recommend replacement after an overcurrent trip to maintain reliable circuit protection. You can make your own tester and is available in any kitchen silverware drawer. Just bend the middle prongs of a fork and stick the unbent prongs in the receptacle. (^^DON’T ^^ DO ^^ THIS^^)

Not true. Google "GE AFCI shared neutral". It will return a GE white paper discussing this. I tried to post a link to it, but RU-vid wouldn't let me.

Think he’s referring to a 2-pole breaker, with a tie bar. Not a completely separate circuit.
