Thanks guys.

At this point I think we have ampacity of the transformer worked out.

On the primary side we have a full load current of 90 amps

On the secondary side we have a full load current of 208 amps.

Now we need to figure conductor and breaker sizes keeping in mind that we want the maximum capacity from this transformer.

The connected load to this transformer is 75 KVA continuous.
