5.1 Generator Derating
Description
All generator sets are subject to derating (reduced power output) depending on the
altitude and ambient temperature. Derating should not affect the operation of the
floodlights, although it will reduce the available reserve power to the receptacle.
Derating
percentages
Power ratings are typically reduced by the following percentages:
■ 3% per 300 m (1000 ft.) elevation above sea level
■ 2% per 5.5°C (10°F) increase in ambient temperature above 25°C (78°F).
