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.
