Opinions with code references please.

Optional Standby Generator with 600 amp breaker in onboard enclosure, Service Rated and Listed by special order.

Generator is SDS and sits 50' from entrance into mech room where another switch is installed adjacent to Normal power MDP.

Does anybody know of a reason per any codes that there should be a Service Rated Switch installed closer to the building, or that the interior switch should be located nearest point of entrance per 230.70(A)(1).

Also with this Service Disconnect located at the Generator, wouldn't we be meeting 230.72(B)?
