215.2(B)(1)

[charlie b]

A privatized utility company literally owns the MV overhead and underground distribution system at a military base, including all service transformers. Their contract with the government invokes the NEC. They will have a "set of conductors" that are connected to an MV switch, and that provide power to a number of service transformers in the area. They use the term "feeder" to describe this "set of conductors."

Question: Is this "set of conductors" required to be sized to handle the total of all the nameplate ratings of all the transformers? That is, does 215.2(B)(1) apply? Are the conductors actually not "feeders," in the context of that article, and are they "service conductors" instead?

Where does the private utility say the service point is? I believe they are feeders and 215.2(B)(1) applies.

The private utility owns the transformer. The point of demarcation is the transformer's secondary terminals.

I envision this article coming into play at a university campus. The utility ends at their substation located on campus, The university runs MV feeders from that substation to transformers next to each building on campus. These would qualify as "feeders" because they are downstream of the utility and upstream of the final branch circuit OCPD.
