Generator sizing tools and data AT YOUR FINGERTIPS.

Attention consultants, architects, engineers, and contractors! SpecSizer and the Technical Information Portal were designed to help you get the right-size generator set and all the information you need for every one of your projects.

 

Electric Power SpecSizer

SpecSizer uses factors such as site conditions, load characteristics, and required performance to give you accurate and timely technical data, load models, and optimized algorithms to specify the precise generator sets to best meet your power needs. SpecSizer evaluates load types such as air conditioners, elevators, ultraviolet lights, single-phase NEMA, and single-phase IEC motors. It collects data on your loads, then organizes them into steps, factoring in voltage dip and load demands, to help you select the best generator set size in both rating and footprint.
