Service equipment

[Djelite]

In a separately derived system the service equipment (disconnect) is the transformer disconnect. Why not just call the transformer disconnect a service equipment?

Because it's not? Look to the NEC's definition of a service-

The conductors and equipment for delivering electric energy from the serving utility to the wiring system of the premises served.

That may seem like an arbitrary distinction, but it's there.
