An electrical service (Meter On Pole ? MOP) is on its own pole and is supplied by an overhead service drop. From the load side of the meter's OCPD feeder conductors continue under ground to a residential house distribution panel. For a single-phase 240/120 service how many conductors are required to run from the MOP to the house distribution panel? Two hots a Neut and Ground? Two hots and a Neut? Does 250.32(D) apply to this service? Is the MOP considered a ?Separate Structure??
How does this work for a non-residential services were a larger grounding electrode system is employed? It would seam by 250.32(D) that the grounding electrode conductor of this larger grounding electrode system would be connected to the equipment grounding bus at the panel of structure 2 instead of the isolated neutral bus and a single ground rod is connected to the neutral bus at the MOP?
Please enlighten me? Thanks
