A correction to my earlier answer(8)
In case we are to use a 3 phase generator then the total
current of 218.75 has to be equally shared between the 3
phases i.e. Iph=218.75/3=72.9 Amps.
So the genset rating would be again 52.5kVA(1.732*415*72.9).
But in actual as the number of AC's is 20;
18 Ac's get distributed equally (6 on each phase L-N) and
the balance 2 nos will be on one phase each.
So the max current will be 76.58 (18/3*10.94+10.94).
So the 3 phase genset rating would be 55kVA (1.732*415*76.58)
