I have a customer installing a new computer / server room.
They will have (280) pieces of equipment @ 1.5 Amps /120 volt and (10) pieces 2A / 208 volt - All single phase loads....
Plus they would like to have a 60A /3 Phase Rooftop unit to run of the generator also.

280 x 1.5A x 120V = 50,400 Watts
10 x 2A x 208V = 4,160 Watts
1 x 60A x 208V x 80PF x 1.732 / 1000 = 17,300 Watts


Calculated load = 71,860 Watts.

Is this correct?
