From the information given in the illustration, what would be the maximum output amperage available from the emergency generator if it operated with a power factor of 0.9? EL-0106

Correct Answer: Option B — 669 amps

Apparent power capacity divided by voltage and the power factor yields maximum available amperage. At a 0.9 power factor, the emergency generator rating calculation results in 669 amps according to marine electrical engineering principles outlined in IEEE 45.
