Could you have a 15kv transformer fed by 2 legs of a 480v wye to a 120/240 single phase secondaryoutput with no secondary protection (200 amp main in panel).
Oh sorry primary would have 40amp fusing.
I believe from 450 chart for transformer you can do primary only protection.
I also believe the main for that panel fed from secondary is necessary and about 85 amp breaker.
Is that breaker required in the panel and if so I assume a 200 amp would not be code compliant. I could not find the rule
