Of my post of the 65 percent ( % ) of the grounded conductor current returning on the water GEC, I did not open the water GEC to check the voltage across the open connection for I did not want to take a chance on doing harm to some load equipment.
I suspect that the actual VD would not have be very high voltage because of the near-by ROD GE (Grounding Electrode).
But, I do wonder of the dangers of someone servicing the water piping.
The city's water piping had a 14" line about 8' from the utility transformer pole and ran by several utility primary lines' poles. There was/is also a 6" water line on the opposite side of the street which supplied water to at least three of the dwellings, maybe all of the dwellings, served by the transformer.
It just doesn't seem correct to have 65 % of the unbalanced current returning to the source on the water GEC. It certainly is not returning to the transformer with the "circuit conductors" as implied by 250-24(b)(1).
I wonder what would happen if a bolted ground fault would occur at the service panel.
