Fuel Stop power in accordance with ISO power (kWe) must be considered cooling fan loss, alternator efficiency, altitude derating and ambient POWER RATING is applicable for supplying emergency power for the duration of the utility power overload capability is available for this rating. A standby rated ENGINE should be sized for a maximum of an 80% averageload factor and 200 hours of operation per year. This includes less than 25 hours per year at the Standby Power rating. PRIME POWER RATING is available for an unlimited number of hours per year in variable load application.

2 Variable loadshould not exceed a 70% average of the Prime Power rating during any operating period of 24 hours. The Total operatingtime at 100% Prime Power shall not exceed 500 hours per year. A 10% overload capability is available for a period of 1 hour withing a 12 hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year.
