Do I need to take special consideration for ground and neutral connections on the secondary of a Electrostatic Shield Isolation Transformer? Its a delta-wye 480 - 208/120. I've heard that you bond the neutral and ground at the transformer...if so...How do I deal downstream with grounding the panel frame without creating a parrallel return path? Many thanks for any help....reference to a wiring diagram would be great!

Thanks folks!

Ground the transformer like any other. One neutral to ground bond, either at the transformer or at the panel. With only one neutral-ground connection, there are no parallel return paths.

The shield is typically bonded to the transformer frame.
