There is nothing more to this, really. But being a layman, sometimes I think up something ridiculous to the pros. This question felt lousy even as I was typing, but decided to post it anyway. What I know about AFCI is 0.
Since I wire the house myself, I test the roll when it's in one piece and simple. I probably take 5 times more time to wire, never yanking it, snug staples, using the metal plates probably more than needed, etc. But if cheap enough, I will get the megger and use it.
AFCI being a different kind of "sensor" and I don't know about the quality of wire insulation, I thought the pros may have a tester that makes certain that the cable is good. I just bought 5 rolls of 14 and 12-2. With gas price going up again, I think I will save a few cents.:smile:
