Comments F G Wilson P22-P30E P22 – P30E OUTPUT RATINGS Generator Set Model P22 P27 P30E 380 - 415V, 50 Hz 22 kVA 17.6kW 27kVA 21.6kW 30kVA 24kW 480 V, 60 Hz 25 kVA 20kW 30kVA 24kW 34kVA 27.2kW Rating definitions Continuous Power – Models P22 and P27 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 these models can supply 10% overload for 1 hour in 12 hours. Standby Power – Model P30E These ratings are 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 alternator on this model is peak continuous rated (as defined in ISO 8528-3) at 27 degrees C.
