* Disclaimer: Because of the tremendous amount of variables that exist in generator power provision and transmission, Absolute Generators strongly suggests that you seek the advisement of a certified electrical professional familiar with your situation (and potentially local electric code when performing permanent installations). Information offered by this generator power calculation page, though a useful tool for general estimating, requires consideration of circumstances specific to your application including, but not limited to: electric motor efficiencies (or lack-there-of), altitude, derating of generator power based upon fuel type, prime power versus standby power concerns, simultaneous versus varied timing of loads, site conditions, iron losses, etc... Please contact us at customerservice@absolutesuppliers.com or 888-264-2189 with your specific situational needs and concerns. Complex electrical calculations beyond that which is represented by the above page requires consultation with onsite certified electrical professionals. Because of the unlimited variables that exist in generator power situations, Absolute Generators accepts no liability associated with your use of this page and the information it provides.
