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.
