So, if I am going to install the following:

Three (3) single phase 480 to 240/120 25kVA transformers
One (1) single phase 480 to 240/120 10kVA transformer
One (1) 15 HP 480V 3PH motor

What size "three phase transformer" will I need?

Does this chart i put together look right for what I'm installing? Assume it's fully loaded (got these amp values out of an ugly book)

25kVA 25kVA 10kVA 25kVA 15HP TOTAL AMPS PER PHASE
Phase - A 52.1 20.8 52.1 31.3 156.3

Phase - B 52.1 52.1 31.3 135.5

Phase - C 52.1 20.8 52.1 31.3 156.3


If correct I would need a 200A 3PH distribution panel and a 100kVA 3PH 480V transformer???
 
So sorry, this was meant to be posted within my previous post
