Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage.  No overload capability is available for this rating.  (All ratings in accordance with BS5514, 

ISO3046 and DIN6271).  * Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc.  Maximum power 

decreases about 3.5 percent for each 1,000 feet above sea level.  Sound output ratings from certain points on the generator subject to change based on installation parameters.
