That depends mainly on the use of that building. Domestic / office / factory each have different load influences.
Can you provide some details here on the building use, size, location, weather influences, etc ?

It depends on the supply voltage 440/220 or single ph.or 3phase.
So if we know the supply voltage & the phase we can compute the right size
Of wire and breaker

300 Kva is the max load.

if you are looking for the load in amps, need to know the voltage.

For example, if the voltage is 480, then:

KVA= I*E*1.73

I = KVA / E*1.73

I = 300 KVA / 480*1.73

Amps is 361.27
