Remote panel use question

[M. D.]

But what about the language in 250.50 and 250.52(a)(1)

...10' or more and electrically continuous (or made electrically continuous by bonding around insulating joints ....)....

Would those jumpers have to present or are we required to bond around the insulating joint???

Or can we just ignore it as an electrode??

It almost sounds as if we are required to bond around it / them until we achieve the 10'

going to give that more thought before I give an opinion

While you are thinking ,.. take a peek at 250.6(b) I think this could be used ..

Don't think I ever read that, but I don't recall encountering "objectionable current". Can we call this "objectionable" ? Only object is it prevents us applying that Code article
Taking 250.52(A)(1) literally, it would seem you would need to bond to the UG water if it were on the property, no matter how far away.
Back to the OP. If we consider the water mains as establishing a "metallic path", the original install was not compliant.
I am of the unlearned and uneduated opinion that the "metallic path" rule would be to prevent objectionable current thru customer lines and not thru utility water mains as you have that every meatllic water system.
In this sitaution, I can see no differenc betweemn his feeder supply and a seperate service supplying the building. (so I guess I'm back to YES).

Wablsam1, you said in the original post, you already knew the answer. Before I waste any more valuable readers time, what say you ?

I believe the answer to be NO. The reason being that I can find no relief in the Residential Code (which New York uses for one-family dwellings and their swimming pools) for the provision found at E4105.6 which reads:

"A panelboard that is not part of the service equipment, or source of a separately derived system shall have an equipment grounding conductor installed between its grounding terminal and the grounding terminal of the applicable service equipment or source of a separately derived system. The equipment grounding conductor shall be insulated, shall be sized in accordance with Table E3808.12, and shall be not smaller than 12 AWG".

Since this text occurs in Chapter 41 which is titled "Swimming Pools" I believe it takes precedence over other provisions in other Chapters.
