Glenn35,

It does sound like a bit of overkill to me. By way of comparison, the underground service installed by the utility here (LI, NY) for 200A service is only 1/0AL ! and distances over 100' are common. One 4/0 would be twice the size of our 1/0 for the same size service. That would probably be acceptable if there is no chance of ever needing over 200A service.
