320A?
What the heck is that?
I don't understand hoops with 400, but ....
Sounds strange....

Sounds like his utility co isn't blowing smoke like most of them do.
A 2 minute conversation with engineer at my utility concluded that they can hang 3 real 50KVA transformers on my pole for a real, continuous rating of 361 amps at 240V and for a very low cost. If I want more than that my wallet was going to hurt. He told me in no uncertain terms there's no such thing as a nice neat 400 amp service. Doesn't work that way. Those are just ratings on the equipment, not what you actually get.
Makes sense to me.
