Art. 450 references these but appears to only refernce them as autotransformers.
With a Harmonic Migating Transformer, 480Dx208Y120, this would go back to seperate derived systems, would it not?
This is my first time installing them, and they appear to be a just a zig zag Y. And should be bonding and grounded just like a standard 208Y120, would they not?
Any I did a search and there is not too much info about these here, anyone have any pointers?
Would these require double size nuetrals similar to a K Factor?
