OK how about if the electrode in question is a Ufer. I pick it up at the service disconnect and 300' away I find another piece of turned up Rebar, can I bond my water to that?
I think that is an excellent question.
Here is my answer.
I do not consider the cement itself to be an electrode. Think of what the NEC calls it.
"Concrete-
Encased Electrode"
That being the case you would have to hook into the electrode itself not just another rebar.
IMO the rebar would have to be tied together continuously for that 300' in order to do what you ask.
Personally I would not be comfortable doing it that way but IMO the NEC allows it.
