As I read the NEC 2008 draft, it looks to me that ALL 15 and 20 amp residential branch circuits will be required to be ARC fault. So that must mean that any 220 volt 15 or 20 amp circuits (like A/C) will be required to be arc fault. And what about all the circuits now required to be GFCI (bath, kitchen, outside, etc.)-they will now have to be arc fault also? I heard, but have not seen that some arc fault breakers are also GFCI, but are they 30ma or 5ma and do all the manufactures have these?
