Ok, so it sounds as if it is acceptable to tap off the GEC as long as the GEC remains unspliced and the connector is approved for grounding and bonding. A split bolt is not approved for this.
As far as tapping off the cold water supply for the secondary ground, we would need to keep that within the 5' of entrance rule.
Sound about right?
I'm going to check with the supply house about approved connectors for this. We only carry cold water clamps, acorns, split bolts and parallel groove connectors on the truck.
