I have fire pump 125HP 208V three phase. Trying to convert 125HP to kVA.
Based on NEC Table 430.250 125HP is 343A at 208V three phase.
343x.208x1.733=123.57kVA.
Now if I use calculator internet to convert assuming 100% efficiency and 0.8 PF then I get 116kVA.
Which is correct or both are incorrect? What should be used to convert when sizing panelboard load calculation?
