The service panel must be grounded to all available electrodes. The cold water pipe enters the house at the front but my service panel is at the rear next to a hose bib. I connect to the hose bib and that serves as my grounding electrode.
250.52(A)(1) reads:
"Interior metal water piping located more than 5 feet from the point of entrance to the building shall not be used as part of the grounding electrode system..."
The hose bib I clamp to is on the exterior of the building, it is not "interior metal piping" even though it is 60 feet away from the point the water service enters the building.
I have been doing this for years and have never had an inspector issue a correction, I assume my reading of the code is correct.
What say you?
