means meeting the requirements of the NEC and this subsection.
The disconnecting means must have an identification plate with
at least one-half-inch high letters identifying:
(i) The building/structure served; and

there is a feeder disconnecting means, located elsewhere on
the premises, with overcurrent protection sized for the feeder
conductors.
