Service: The conductors and equipment for delivering electric energy from the serving utility to the wiring system of the premises served.
Assume multiple services are allowed to a given structure per 230.2. Can these separate services all be fed from the same utility transformer? That's how I read Article 100.
Each of these services is then allowed up to six disconnects per 230.71. As I read this, these disconnects must be grouped, but only with the other disconnects for the given service.
So theoretically one could have three services each with six disconnects, and each set of disconnects could be located in a different part of the structure.
My specific example is a large apartment complex with two meter stacks. each meter stack is fed from the same transformer but counts as a separate service. The house loads are a separate service also.
Say the house load uses the six-disconnect rule, no main. The meter stacks are each located in opposite ends of the building and have their own disconnect located at the stack.
Is it OK to not have all the disconnects to the building in one location? I can't find anything in the code that says its not, assuming these disconnects are separate services and that multiple services can come from one utility transformer. I think my logic is OK but maybe am missing something. Thanks.
EDIT: clarified the location of meter stack disconnects.
