Looking to see if I'm going to get myself into some problems on the neutral for 120/208 panelboard.

Distribution transformer 3phase 500kVA Delta prim. and grounded Wye 208V

Panelboard is 100A 3P, 4W.

Idea is to run #2awg off the X0 of 500kVA Transformer to the panel. I should be ok if the X0 is grounded properly?
The neutral for the panel will be run on it's own. I feel like i'm missing something.

Thanks,
R.L
