I searched and I don't think I'm ok.
200kVA 600 to 208Y/120 Transformer.
600A Panel w/ 400A main breaker on the low side. My electricians ran 500MCM between the transformer and the panel, but since the pull was hard, they ran a 4/0 neutral.
Should I have them redo it? Loads are trailers fed from 70A fusible disconnects.
