*Continuous Power Rating: The highest electrical power output of the Enginator available for an unlimited number of hours per year, less maintenance. It is permissible to operate the 60
Hz Enginator units with up to 10% overload for two hours in each 24 hour period. NO overload is allowed for the 50 Hz units.
Rating Standard: The Waukesha Enginator power rating descriptions are in accordance to ISO 8528, DIN6271 and BS5514. It is also valid for ISO 3046/1-1995 with an engine
mechanical efficiency of 90% and auxiliary water temperature Tcra (clause 10.0) is limited to ±10° F (5° C).
**Heat rejection based on cooling exhaust gas to 85° F (29° C).
