Both Seimens and Square D 400 amp meter panels sold here are split 200 amp services with a supplied breaker for each as Mr. Matt said.
I ran 200 amp to my shop with 4/0 copper because of the 175' length. The other 200 was split between two sub panels in the house and the garage.
Must of been before copper was almost expensive as gold. For the 200amp service at the house I was working on I used 4/0-4/0-2/0 AL Feeder and then a 4/0-4/0-4/0 to main panel from meter.
