Ratings Definitions
Prime Power – Model UG14P1
These ratings are 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 this
model can supply 10% overload power for 1 hour in 12 hours.
Standby Power – Model UG16.5E1
These ratings are applicable for supplying continuous electrical
power (at variable load) in event of a utility power failure.
No overload is permitted on these ratings. The alternator on this
model is peak continuous rated (as defined in ISO 8528-3).
