Arc-flash on Grounded-B system
(OP)
Anyone have suggestions for conducting an arc-flash study on a 480V, three-wire, grounded-b system? Is this possible? If so, should it be treated as an ungrounded-delta? Not sure where to start with this one... TIA!

One has a grounded system. Use the grounded fudge factor. Treat it as any other grounded 480 volt system.
