Max demand shopping centres and alike
VA per square metre eg 35 va /sq metre or as given by consultant
1017 sq metre floor area x 35 va / sq metere = 35,595 or 35.595Kva
√3 x Voltage (3 phase) x I = 35,595 or 1.732 x 415 x I = 35,595
Or I = 35,595 ÷ 1.732 x 415 = 49.52 Amps per phase
Single phase calc forget the √3 and adjust voltage to 240
