I am working on a job and trying to get it final on it. It is a comercial building. It has both 120/208 panels and 277/480. The inspector is telling me I have to lable every panel in the building with a color code of what is in the panel. Can anyone help me find a code section that states this? This job is on the 2008 code.
 
Try 210.5(C)

210.5 Identification for Branch Circuits.
(A) Grounded Conductor. The grounded conductor of a branch circuit 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 branch circuits supplied from more than one nominal voltage system, each ungrounded conductor of a branch circuit 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 branch-circuit panelboard or similar branch-circuit distribution equipment shall be documented in a manner that is readily available or shall be permanently posted at each branch-circuit panelboard or similar branch-circuit distribution equipment.

210.5(C)

"The method utilized for conductors originaiting in each branch-circuit panelboard or similar branch-circuit distribution system shall be documented in a manner that is readily available or shall be permanently posted at each branch-circuit panelboard or similar branch-circuit distribution equipment."
 
The NEC is not telling you what colors to use for the ungrounded, only that you identify each phase or line with different colors, and that you identify each line or phase where terminated or connected

Also the neutrals may be required to be different colors for each system, see 200.6 (D)
