There are numerous references to Identification of Conductors throughout the NEC. The electrical guy needs to determine what and how based on the specific reference. Sorry but I just don't have time to go through them all right now. Look at Article 215 FEEDERS,
215.12 Identification for Feeders. (A) Grounded Conductor. The grounded conductor of a feeder shall be identified in accordance with 200.6. (B) Equipment Grounding Conductor. The equipment grounding conductor shall be identified in accordance with 250.119. (C) Ungrounded Conductors. Where the premises wiring system has feeders supplied from more than one nominal voltage system, each ungrounded conductor of a feeder shall be identified by phase or line and system at all termination, connection, and splice points. The means of identification shall be permitted to be by separate color coding, marking tape, tagging, or other approved means. The method utilized for conductors originating within each feeder panel board or similar feeder distribution equipment shall be documented in a manner that is readily available or shall be permanently posted at each feeder panel board or similar feeder distribution equipment.

Does there need to be some identification at the transformer denoting that a feeder goes to a fire pump so it won't be inadvertently disconnected. The reference you sent seems to only apply at disconnect locations.
