Again, your eloquence is outstanding!
That's the basic scenario here in NJ, probably the same in Ma.
800 amps is max OH (from pole mtd pots), larger is pad mount xfr. PSE&G area, layout tech determines locations; EC responsible for pad sub-base; EC installs primary conduit(s)from pad to PSE&G designated location (to PSE&G specs). PSE&G installs and terminates primaries. EC is responsible for all secondary work. CT's & meter pan are supplied by PSE&G; PSE&G wires CT's and meter. All is done to PSE&G Green Book 2005 with amendments (3).
The Green Book, and amendments is available on the internet at PSE&G website.
