To determine the total wattage required to run a particular electrical appliance or tool, multiply the voltage
figure of the appliance/tool by the amperage (amps) figure of same. The voltage and amperage (amps)
information can be found on a name plate which is normally attached to electrical appliances and tools.
NOTE
The following wattage chart is general guide only. Refer to your specific appliance for
correct wattage.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS
When a long electric extension cord is used to connect an appliance or tool to the generator, a certain
amount of voltage drop or loss occurs in the extension cord which reduces the effective voltage available for
the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when an extension
cord of 300 feet
(approx. 100 meters) is used to connect an appliance or tool to the generator.
