Re: code challenge
the definition of service and therefore "service equipment' or feeds does fit this situation and is distinctly prohibited from passing thru another building or seperate residence. If the units are served by diferent meters and the assumption is that there are no circuits shared by units, then the service feed to that unit cannot pass thru an intermediate unit, and that includes feeds to distribution panels downstream from the main disconnect. It must be outside of intermediate buildings, apartments, condos, townhouses. If under 2" of concrete, that will satisfy the requirement.
this has always been a requirement as far back as i can remember.
the assumption is that all circuits passing thru a premises can be disconnected by the OCCUPANTS, not the occupants and their neighbors.
