Choose bus ampacity

[vtb1]

I have transformer with 115/13.8kV, 24/32/40 MVA, %Z=13.2.
How can I find bus ampacity?
Is it necessary to consider 150% overload capacity?

At 13.8 kV and 40,000 kVA(Top Rating) the current will be about 1675 amps. What does your code say about overload? How do you plan to operate the unit. 2,000 amps would give you about 20% over the top rating of the unit.
