I'll also sympathize with all the homeowners who have 20 space 40 circuit panels now and they want to add a new circuit in 2008. Will there be any open slots for an AFCI? Will anyone make a tandem breaker that is AFCI? The panels are going to run out of slots if most of the circuits will require breakers that only come in the full size category and not tandems.

There's nothing quite like a Square D QO 100-amp, 32-space subpanel to add those full-sized breakers and circuits they need.

If they get the arc faults to really work, then we can relax the requirement for receptacle spacing since extension cords won't be a hazard. One receptacle per room again--ah the good old days.

This could really drive down overall costs.

Reminds me of how my bedroom was-- only two outlets in a 15x17 room. It was... interesting to find a place to plug things in. (Then they came in and installed outlets and only two of them share an AFF height, but that's another story).

You'd have the same issues with a 40-space/40-circuit panel.

Larry, Who makes an AFCI twin CB?
The point Markp is making is there won't be an application for a 20/40 panel if the only single pole breakers available are full size. A 20/40 will just be a 20.

When the 2008 comes out and if the whole house requirement is in it how long would it be before the manufacturers started making AFCI main breakers?
The cost for the mains would skyrocket and the manufacturers could still market the 20/40 panels.

Do AFCI breakers have a high defect rate? 1 of the AFCI breakers I just put in trips even with no load connected. $35 for THAT kind of quality assurance? Gives me a real warm fuzzy on them doing their job if there IS an arc...

AFCI the main? I bet that would be popular. A little water in your outside outlet and the freezer defrosts.

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...
