Reading thru mfg info (Sq D & Siemens, so far) the combo detects series and parallel arcs, as I understand it.
Keep in mind that here in NJ AFCI will not be mandatory until the '08 is adopted. Comments to DCA are due before 12/16/2008, and adoption will be 6 months after it is entered into the UCC.
I noticed in the big box store that Sq D * Siemens AFCI CB's are marked down; approx 50% to the $15-$20 range. I venture a guess that the ones on the shelf are NOT combo rated, and are the 'old' type. Only if I know how to distinguish between the 2 without a catalog!
PS: Sq D & Siemens have a lot of info thru there websites.
EDIT: I just noticed this is the TP thread....ooops! Harold are you starting a thread jack??
