I am rewiring a home damaged by a major water leak, replacing all wiring on first floor, and have to bring entire home up to 2002 code. The second floor 3 bedrooms were previously rewired. There are four circuits fed by 2 #12 3 conductor w/g from basement panel. Question is, how can I wire in 4 arc circuit breakers with only the 2 neutrals and still meet code?
Thanks, B.C.

If the panel is a BR type panel you can use two-pole AFCIs.
I don't know of any others being sold.

Yes it is a BR type. Glad I didn't drop a bundle on anything else.
I checked around, and Home Depot men (2 licensed guys)told me about the 2 pole.
I went to a local distributor, and they ordered 2 for me.
Technically, its called an I.T. 2 pole. Independent trip for 2 circuits with a common ground. Thanks a lot for your help. I was really sweating this one out. The inspector lives around the corner and stops in daily.
