Did you mean that the inspector could ask that the conductors feeding the panels have to be as large as the conductors coming down to the meters?
Wouldn't skeffibew1's use of the mains at the meterpan preclude that possibility? As they would be SER's at that point?
The inspector needs to know if the conductors feeding the two meter stack are large enough to handle the connected load. One way to do this is to perform a load calculation. The other is to simply install conductors that are large enough for the worst possible case scenario which would be the total of the two loads.
For example, a fairly standard installation if you had a two family, would be a two meter stack with two 100 amp panels one for each apartment. You could simply use a set of 200 amp conductors to feed the meters and everyone is happy. Or go the longer route and perform a load calculation and maybe save some money by using smaller conductors to feed the meter stack.
