^ The Standby Power Rating is applicable to emergency power applications where power is supplied for the duration of normal power interruption. No sustained overload capability is available for this rating. This rating is only applicable to variable loads with an average load factor of 70 percent over 24 hours of the standby rating and for a maximum of 200 hours of operation per year The standby rating is only applicable to emergency and standby applications where the generator set serves as the back up to the normal utility source. No sustained utility parallel operation is permitted with this rating.
**The Continuous Power Rating is applicable when supplying electric power in lieu of commercially purchased power. The number of allowable operating hours per year is unlimited for variable load applications but is limited for constant load applications.
