it is a feeder, so 230.2 (i believe) would not apply, 225.30 OTOH...
225.30 Number of Supplies.
Where more than one building or other structure is on the same property and under single management, each additional building or other structure served that is on the load side of the service disconnecting means shall be supplied by one feeder or branch circuit unless permitted in 225.30(A) through (E). For the purpose of this section, a multiwire branch circuit shall be considered a single circuit.
would seem to consider outbuildings downstream
of the main service, limiting the # of feeders or branch circuits per stipulations.
there are two building on the same property here, via the same owner, each has a service drop.
is a large long 5 unit apt house w/barn.
is being supplied from building B's
exclusive service, via a feeder to A
what am i missing?
