Pardon my ignorance on services of this size:

I have a commercial bid for a service that will start out with a 320A meterbase, go to a disconnect, then be split into two 200A Feeders for two 200A Panels.

1) Does the Disco need to have Main protection at 320A? (Odd size...)

2) Does the Disco need to have two 200A Branch Circuit Protection, one for each feeder?

3) If not, how do I connect two 3/0 Cu Conductors to one lug?

I haven't done any services over 200A as a contractor and none after inspections were required, so I'm not sure if the way I was taught is right...

</pardon my ignorance>

Thanks in advance...
