All generators are rated in Kilowatts (KW). This table will
allow you to compute how large a generator (in KW) you need to service the desired
loads. Pay attention to the figures in the “Load (in KW)”
column. This will let you see which items substantially increase the size and cost of your system. The values
below are approximations only. Formal calculations will be conducted and
submitted with your permit package.
