Dual services...sort of

[robgrant3]

I am working on a building and it has a aerial utility feed from a pole to the building. The conductors go into a splice box, and feed two separate panels, each with a GEC bonded neutral. I am trying to rework the GE system so I can meet 2005 code, but I am confused as to how many GEC/ground rods I should have. Should I re-feed one of the panels through the other, and use the first as the main disconnecting means, and bond the neutral here?

If both panels have mains it sounds perfect the way it is.

250.58 Common Grounding Electrode.
Where an ac system is connected to a grounding electrode in or at a building or structure, the same electrode shall be used to ground conductor enclosures and equipment in or on that building or structure. Where separate services, feeders, or branch circuits supply a building and are required to be connected to a grounding electrode(s), the same grounding electrode(s) shall be used.
Two or more grounding electrodes that are effectively bonded together shall be considered as a single grounding electrode system in this sense.

Make sure this installation does not violate this article. :smile:
