In Article 100, titled Definitions, of the 2020 Edition of the National Electric Code, the definition of premises wiring includes "wiring from the service point" to the outlets. The other definitions are: service:

The conductors and equipment connecting the serving utility to the wiring system of the premises served.

service conductors:

The conductors from the service point to the service disconnecting means.

service conductors, overhead:

The overhead conductors between the service point and the point of first connection to the service-entrance conductors at the building or other structure.

service point:

The point of connection between the facilities of the serving utility and the premises wiring.

service drop:

The overhead conductors between the serving utility and the service point.

service equipment:

The necessary equipment, consisting of a circuit breaker(s) or switch(es) and fuse(s) and their accessories, connected to the serving utility and intended to constitute the main control and disconnect of the serving utility.

In practice, the service point is never located closer to the home than the connection with the service-entrance conductors and never located further than the connection of the conductors for a public road with the conductors for a private road. All of these questions are regarding NEC definition only.

  1. Does this mean that the service conductors are always part of the premises wiring and never part of the service, making the term an oxymoron?
