Here's the scenario:
UG conduit from PoCo transformer to meterbase and disconnect (about 10' from the transformer) mounted on a free standing wall (outside) designed just to hold the meterbase and disconnect, nothing else (not part of a building). Bond the neutral and drive ground rods connecting them to the service w/#6 bare copper.
Install a PVC conduit abourt 200' to a 2nd disconnect (mounted on a free-standing wall not part of a building), but do not pull a ground conductor. Bond the neutral in the 2nd disconnect and drive ground rods connecting them to the neutral bar. Seperate ground and neutral from here to the panel (about another 200').
There are no parrallel paths (conduit, water lines, etc.) between the 1st adn 2nd disconnect. The conduit between the 1st and 2nd disconnect was existing but sized so only the (2-sets 4/0 copper) could be pulled in (2.5" PVC). The customer really wanted to use this conduit since landscaping issues were involved (high end gated community).
The original plan was to go from the transformer to the 2nd disconnect location (installing meterbase there) but PoCo wanted meterbase closer to the transformer and the Fire Marshal wanted a disconnect closer to the tranformer. The AHJ was consulted about this installation and approved it as described above (2 disconnects w/out a ground wire between them).
From reading on this Forum, I believe this would be OK prior to 2008 NEC, but is not in 2008 NEC. ???
Is there any real danger in the installation described, and what is the danger?
Thanks,
