Thing is two-pole AFCI's are almost non-existent right now. Those who offered them don't any more as far as I can tell. I agree with above. Just do one circuit per rom and use SP breakers.

Secondly, why would you want to put an AFCI on a MWBC. If there is a fault both circuits would trip.

I have a feeling you are addressing the OP. That was two years ago. I was addressing zoko with his added-on question.

I would much rather have the benefit of a MWBC and deal with the extremely rare occurrence of a two-pole breaker tripping.

Also around here a 2P AFCI goes for $100 and is a waste of money. Most mfg have only corrected the SP AFCI which were constantly tripping. The problem was not corrected in the 2P AFCI.
