PRIME POWER RATING is applicable for supplying electric power in lieu of
commercially purchased power. Prime Power applications must be in the form of
one of the following two categories:

UNLIMITED TIME RUNNING PRIME POWER
Prime Power is available for an unlimited number of hours per year in a
variable load application.Variable load shouled not exceed a 70% average of
period of 250 hours.
The total operating time at 100% Prime Power shall not exceed 500 hours per
year.

A 10% overload capablility is available for aperiod of 1 hour within a 12 hour
period of operation.Total operating time at the 10% overload power shall
not exceed 25 hours per year.

LIMITED TIME RUNNING PRIME POWER
Prime Power is available for a limited number of hours in a non-variable
load application. It is intended for use in situations where power outages are
contracted, such as in utility power curtailment. Engines may be operated
in parallel to the public utility up to 750 hours per year at power levels never to
exceed the Prime Power rating.The customer should be aware, however,
theat the life of any engine will be reduced by this constant high load
operation. Any operation exceeding 750 hours per year at Prime Power
rating should use the Continuous Power rating.
 

STANDBY POWER RATING is appliable for supplying emergency
power for the duration of the utility power outage. No overload capability
is available for this rating. Under no condition is an engine allowed to
operate in parallel with the public utility at the standby Power rating.

This rating should be applied where reliable utility power is available. A
standby rated engine should be sized for a maximum of an 80% average
load factor and 200 hours of operation per year. This includes less than
25 hours per year at the Standby Power rating.Standby ratings should never
be applied except in true emergency power outages.Negotiated power 
outages contracted  with a utility company are not considered an 

CONTINUOUS POWER RATING
Applicable for supplying utility power at a constant 100% load or
an unlimited number of hours per year. No overload capability is
available for this rating.

Reference Standards:
    BS-5514 and DIN-6271 standards are based on ISO-3046.

Operation At Elevated Temperatrue And Altitude:
   The engine may be operated at
            1500RPM up to 5,000 ft.1,500m) and 104F (40℃) without power deration.
    For sustained operation above these conditions, derate by 4% per 1,000ft.(300m),
and 1% per 10°F (2% per 11℃).
