To determine what size generator best suits your purposes simply tally the power requirements of the equipment you wish to run using the start-up wattage where applicable.
2.
The chart below gives two wattage ratings for some of the equipment listed. The "start-up" wattage is the peak load that is required for a short period of time when any appliance with an electric motor first
starts. The running wattage is the approximate wattage required after this period during
normal operation.

The wattage ratings indicated in the above chart are
approximations only. You should always check the exact start-up and running wattage
of your equipment. If a wattage rating is not indicated on your piece of equipment
you can calculate it by multiplying the amperage draw by the rated voltage. (Example: 15
amps x 120 volts = 1800W). If your equipment does not have power requirements listed
at all please check with the equipment's dealer for its start-up and running wattage
requirements.
