Marine Generator: The Marine Generator engine rating is the power available under normal varying electrical load factors for an unlimited number of hours per year in commercial applications. This rating incorporates a 10% overload capability, and conforms to ISO 8528 "prime power". Average load over a 24 hour period shall not exceed 67% of the prime rating, of which no more than two hours are between 100% and 110 % of the prime rating.
The Marine Generator rating is restricted to generator applications only. The criteria used to establish Marine Generator application ratings is the same used to establish Industrial Prime Power Generator application ratings.
