STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor nameplate the starting
and running voltage and amperage requirements. Use the following
formula to convert voltage and amperage to wattage:
Volts X Amp = Watts
Example: 120 volts x 10 amps = 1200 watts
2. To determine the approximate starting wattage requirement for most
appliances and tools with inductive type motors, multiply the wattage that
was calculated by 2 to 4 times to assure adequate generator capacity. If
the nameplate information is not available use the values on the following
chart as a guide.
3. Remember that the starting and running wattage for resistive loads are the
same. (Example: a 100 watt light bulb requires only 100 watts to start.)
Most resistive loads will be listed in wattage.
To select the right generator for your needs, total the wattage
of the items to be run at the same time.
