I was asked if how much Hp rating of elevator was applicable for a 150kVA transformer supply.

I assumed the following data:
-3phase
-380V
-90% efficiency

Iconnected = (150kVAx1000) / (1.732x380Vx0.9x1.25)
= 202.585Amps
Based from table of Motor Currents (Average full load currents of 3phase squirrel cage motor,3ph,4polemotor,50/60Hz)
150hp is the closest Motor rating for a 205 Amps.

Since 50Hp was the typical motor rating of elevator for condominium building, is it safe to presume that 150kVa transformer could supply 3-50Hp Elevator?

Thanks for the comments guys!

Specialist field.
Far too risky to make assumptions.
