2.8. 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 e ective 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.
