Please help me verify I am correct in sizing the feeder to this service.
2 pipes from the meter can to a 1-400amp single phase breaker 75degree terminations.
Each pipe (underground) contains:
2-4/0 Alum XHHW-2
1-2/0 Alum XHHW-2
The home load calcs to 310amps.
The 400amp breaker then feeds 2-200amp main breaker panels (within 5 foot of the 400amp breaker)
from the 400amp breaker each panel is fed with
2-250mcm Alum XHHW-2
1-3/0 Alum XHHW-2
1-#6 Copper THHN2
Is this correct?
I can go to the next standard size breaker (400amp) even though the parallel feed is only good for 360amps correct?
