Current situation: 2008 NEC. Attached garage. 100-amp Main Disconnect in garage. @60' sub-feed cable to 20-space panel in main section of house, finished basement. One #6 EGC (secondary?) from main disconnect to nearby ground rod. Another EGC (primary?) from sub-panel to nearby cold water pipe, with a jumper around the water meter.
I had one inspector tell me that a new primary (?) EGC from sub-panel ground bar to municipal water pipe meets current code. This even though not literally continuous, it relies on the ground conductor in the sub-feed cable and the approved connections in each enclosure.
I had another inspector tell me the exact opposite, that a whole new EGC must run from the main disconnect to the water pipe (and, presumably, remove the existing older EGC from sub-panel to nearby cold water pipe).
Opinions?
