PRIME POWER (PRP)

Prime power is available for an unlimited number of annual operating hours in variable
load applications, in accordance with ISO8528-1. A 10% overload capability is available
for a period of 1 hour within a 12-hour period of operation, in accordance with ISO
3046-1. STANDBY POWER RATING (ESP)
The Standby Power Rating is applicable for supplying emergency power for the duration of a utility power interruption. No overload, utility parallel or negotiated outage
operation capability is available at this rating.
In installations served by unreliable utility sources (where outages last longer or occur more frequently), where operation is likely
to exceed 200 hours per year, the prime power rating should be applied. The Standby Power rating is only applicable for
emergency and standby applications where the generator set serves as the back up to the normal utility source.
All ratings are based on the following reference conditions:
- Ambient - Altitude above sea level – 150 metres - Relative humidity – 60%
temperature – 27oC
