MCC as a Service Panel

[NSmithIN]

I have a supplier who wants to supply a turn-key process control room. The 480Y/277V electrical service to the control room is derived from a 750KVA pad mount transformer. The secondary of the transformer terminates to a MCC equipped with a 1000A main breaker.

Single-line attached.


However, I would expect the service to terminate to a service panel with a main. branch breakers, grounded conductor, grounding electrode conductor, and grounding electrode.

Is there a code violation using the MCC in lieu of the service panel?

Is there a code violation using the MCC in lieu of the service panel?

Is the MCC marked "Suitable for use as service equipment"? (230.66)

See 430.95.

Just buy one listed as service equipment. It is not big deal or added expense.
