Have a 225 amp main breaker panel,2 can, 60 space total, single phase, using a 320 amp continuous load/400 amp non continuous load disconnect. Print calls for 3 4/0 in 2 1/2" c. Do I size my wire going to the disconnect off the continuous load or non continuous first off? Then use 4/0 from the disconnect to the panel. Max load is 221 amps on the panel. More details the better, Just looking for a little direction, thanks?
