Transformer Primary Side automatic wiring sizes

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??

Have you tried selecting the primary side wire and changing the neutral count in the properties pallete to "0"?

I can change the tick marks, but as far as voltage drop and wire size calcs, Revit still includes the 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).

I'm experiencing the same problem . This is a challenge to my attempt to use a system defined feeder schedule.
