    We can only assist with the calculations once we get detailed information of all the loads in watts and/or amperage, along with the voltage and phase.

    A single phase 45 KVA unit will supply 187.5 amps at 240 volts, a 3 phase 45 Kva unit will supply 125 amps at 120/208 volts.

    AC units are not sized with horsepower. Need to know the tonnage, best to know the MCA, (Minimum Circuit Amps), the watts or amps of each PC, what type of lamp you have that uses 150 watts.

    So much missing from your question.
