High leg Delta (high leg B) (red dog B) connection

It is possible to connect a center tap Delta transformer such that B is the “high leg”. See the diagram below. The center point (X4 on our transformers) is grounded. On our transformers, this center point is between A and B, which makes the C leg the “high leg” in that you can get 208V between it and X4. I think we need to change our connection to match the diagram below though, because the NEC requires B to be the high leg.

For a selection of Eaton's dry type transformers please see our Catalog Volume 2 Tab 2.
