Service equipment in non-dwelling units must be factory marked with the available fault current. The field markings should include which information?

The essential information to mark on service equipment is the available fault current. This value tells you the maximum current that could flow during a fault at the service disconnect, which is critical for selecting properly rated overcurrent devices, conductors, and equipment, and it supports safe maintenance and arc-flash planning.

Other details like the calculation date, environment durability rating, or the disconnect type aren’t required as field markings for this purpose, and they don’t provide the immediate, safety-relevant data needed to verify the equipment can safely withstand fault conditions.
