I really don't foresee a main breaker AFCI. I think you're joking(?). Talk about the headaches. Then again, at a two hour minimum per serverce call...
As for the failure rate, I have had quite a few problems with quality as well. I'd say maybe one in ten or fifteen have given me problems, and that adds up. So does the hassle of taking them back. I don't think this new requirement is going to end well...
