3. The running wattage of examples 1 & 2 totals 1150 watts. The starting
wattage of the small refrigerator is 2000 watts which is 1500 watts more
than the running watts. Take this difference of 1500 starting watts from the
refrigerator and add to the total running watts of 1150.
Example 3: 1500 Starting Watts
1150 Running W

TOTAL =2650 Total Watts
Generator must have a maximum capacity of at least 2650 watts.
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.
actual wattage may vary.
items to be run at the same time.
