Got a call from the head state electrical inspector this morning. Seems he objects to a drawing of mine as being non-standard. The drawing in question shows the service neutral passing through the meter base on to the service disconnect where the main bonding jumper connects it to the enclosure and the grounding electrode system. From here a bond wire returns to the meter base to bond the enclosure.
The standard method according to him is to connect the service neutral to the meter base enclosure on its way through to the service. No extra bond wire is used.
Seems to me this violates NEC 250.6 since unbalanced load current is passing through the conductor used to ground the meter base enclosure. I also believe this method to be unsafe, since the load current combined with a poor connection could case excessive touch or step potentials.
Is this method really standard? Any other comments? Thanks.
