480V 4 wire Delta to 3 wire 208 Wye Grounding

[muckmail]

I use to have a chart that showed wire sizes, grounding, fuse breaker sizes
for a 3 wire 480v delta to 4 wire Wye transformer for different KVA transformers. Does anyone have a table like that. I am having trouble determing grounding wires sizes & wire sizes for different KVA transformers.
I must have lost that table some where and I got it off the internet.
thank you,

Any supply house should have one as most transformer companies pass these out to their suppliers.
