RATING CONDITIONS
Ratings – Generator Set ratings are in electrical
kilowatts, operating on distillate fuel.
Continuous – Power and speed capabilities of the
engine which can be used without interruption
of load — capable of 10% overload.
Prime – For electrical service with variable loads —
capable of 10% overload.
Standby – for electrical service during interruption of
normal power.
Power – ±5% power tolerance applicable for
overload/fuel stop power.
Fuel consumption – is based on ISO3046/1 with +5%
tolerance for distillate fuel having an LHV of
42 780 kJ/kg (18,390 BTU/lb) and density or 838.9 g/liter
(7.001 lbs/U.S. gal.). Including all associated pumps.
Heavy Fuel continuous ratings are 9% less than
distillate fuel. Prime and standby ratings are not
available. Fuel viscosity and contaminant capability is
CIMAC Class K55 (700 cSt at 50° C) at 720-1000 rpm.
