STARTING WATTAGE REQUIREMENTS
1. Some appliances and tools will list on the motor name
plate the starting and running voltage and amperage
requirements. Use the following formula to convert
voltage and amperage to wattage:
Volts X Amp = Watts
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.
WATTAGE CALCULATIONS
The wattage ratings
shown are averages -
actual wattage may vary.
WATTAGE Run Start
To select the right generator for
your needs, total the wattage of the
items to be run at the same time.
