well phosgene...
i may as well throw in the proverbial monkey wrench here that seems to follow your Q, (hey, it's for science fer chisssakes) [Linked Image]

the poco would agree with you, where N & G exist as one uninsulated conductor

they'd have little reservation placing meters on steel track housing incorporating a common mettalic h2o supply, ph service, cable, or other mutual interconnections.

heck, within our own trades scope, we could run an unisulated N&G combo overhead areial triplex to an outbuilding 5' away via 250.32 couldn't we?, as long as that outbuilding had such bonded to an GEC.

i've always viewed those pad mounted x-formers close to buildings and within reach of meters with similar concern

section #1 of art 250 delve's into theoretical aspects here, with potential reparations...

C-H posted a great noodle pdf here btw

as to the grander scheme, those countries that do not include the evil noodle have circumvented this problem completely, foriegn devils!, always getting a leg up on us eh? [Linked Image]
