I have a 3 Phase 3 wire transformer with a 480v delta primary voltage. Is there anyway to circuit this up to the switch gear without a neutral wire? I have created a 480v Delta 3 wire distribution system in the electrical settings and assigned it to the transformer yet still it shows a 3 hot conductors and a neutral??
Did this ever get resolved? Seems to still be an issue (Revit MEP 2012). Revit doesn't give you the ability to edit the wire count (it's greyed out).
