STANDBY POWER is the nominal engine power available at

varying load factors for up to 500 hours per year. This rating

conforms to ISO 8528-1 “limited time running power (LTP)”.

The calculated generator set rating range for standby applications

is based on minimum engine power (nominal –5%) to

provide 100% meet-or-exceed performance for assembled

standby generator sets.

PRIME POWER is the nominal power an engine is capable

of delivering with a variable load for an unlimited number of

hours per year. This rating conforms to ISO 8528-1 “prime

power (PRP)”.
