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 ?

please let us know whether the heater is 3ph, n or single phase?

Also what is the supply voltage?

What size of wire use for 60kw?
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

What is the maximum or full load of 300kva 3 phase transformer?

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

Calculation of electrical of cart

Need more details.

30 amps is safest to use in a 60kw heater
