Answer:
Hey J thanks for your question. Its not clear what you mean by all of NFPA but disconnecting means must be marked to indicate their purpose as stated in 110.22(A). Every circuit in switchboards, switchgear and panelboards must be marked as stated in 408.4. Signs must be placed at service entrance equipment indicating each on-site emergency power source as stated in 700.7(A). And emergency circuits must be marked as stated in 700.10(A).
The NEC edition year adopted is determined by the municipality.
