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.
