OPERATION
CABLE SIZE:
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.
Equipment damage can result from low voltage. Therefore, to prevent
excessive voltage drop between the generator and the equipment,
the cable should be of adequate gauge for the length used. The cable
selection chart gives the maximum cable lengths for various gauges of
wire which can adequately carry the loads shown.
