*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
Enginator with up to 10% overload for two hours in each 24 hour period.
Standby Power Rating: This rating applies to those systems used as a secondary source of electrical power. This rating is the electrical power output of the Enginator (no overload) 24
hours a day, for the duration of the primary power source outage.
Rating Standard: The Waukesha Enginator power rating descriptions are in accordance to ISO 8528, DIN6271 and BS5514. It is also valid for ISO 3046/1-1986 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).
