Help with Underground electric...

[Jimmyboy]

I am installing a (200 amp) two gang meter enclosure on the side of a new garage. (The service will be Underground).
The customer wants a 200 amp panel in the garage (on one meter), and the other meter will be for a 100 feeder to a mobile home 20 feet from the garage.
The utility pole is 60 feet from the garage.
Can I run one 4/o (200 amp URD) feed from the pole to the meter, or will I need to parallel two runs (400 amp) ?

With multiple service disconnecting means your service conductors only need to be sized to carry calculated load.

4/0 aluminum ampacity is 180, so if your load calculation is 180 or less you could have up to six service disconnecting means with the sum of their rating being well over 180 and is still NEC compliant. You could have three 200 amp mains as long as load calc is 180 or less but if just a single device you have to size OCPD per the conductor ampacity even if load calc were only 40 amps - makes sense doesn't it?
