From the information given in the illustration, what would be the ampere capacity at full load of each of the main ship service diesel generators if operating at the rated power factor of 0.8? EL-0106

Correct Answer: Option B — 3011 amps

Full-load alternating current capacity is calculated using the standard three-phase power formula: $I = \frac{kW \times 1000}{\sqrt{3} \times V \times \text{PF}}$. Applying rated generator specifications yields the precise 3011 ampere rating required for ship service diesel generator installations under 46 CFR Subchapter J guidelines.
