Standby – Applicable for supplying continuous electrical
power (at variable load) in the event of a utility power failure.
No overload is permitted on these ratings. The generator is
peak rated (as defined in ISO8528-3).
Prime – Applicable for supplying continuous electrical power
(at variable load) in lieu of commercially purchased power.
There is no limitation to the annual hours of operation and
the generator set can supply 10 percent overload power for
1 hour in 12 hours.
