I will have a 320 meter feeding 2 200 amp main disconnects. the outgoing of these 2 disconnects will run up into attic (one feeding 150amp main breaker box 45ft run 4/0-4/0-4/0-2/0 ser cable, the other feeding 200 amp main breaker box 75ft run 4/0-4/0-4/0-2/0 ser cable). Question is do I bond at both disconnects, one disconnect or at the meter?
