4.A standby generator provides backup power to a process fed by a 600 A power distribution panel. The process uses four 100 hp pumps each having an effi- ciency of 85%. Four three-phase motors driving the pumps operate at 480 V and have a power factor of 0.8. Most nearly, the minimum size generator needed is *n="xp (A) 110 kVA (B) 350 kVA C 440 kVA (D) 500 KVA n/ex P D = 4X100 (746) = 35105 185 (2) 351058,8 = 440=1440kVN
