Voltage Drop In Electric Extension Cords - Yamaha EF12000DE Owner's Manual

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) fig-
ure of same. The voltage and amperage (amps) information can be found on a
name plate which is normally attached to electrical appliances and tools.
Applications
Incandescent lamp, Heater
Fluorescent lamp, Electric tool
Pump, Compressor
TIP
The above wattage chart is general guide only. Refer to your specific appliance
I
for correct wattage.
I When you use two or more alternating current outlets at a time, be careful that
the sum of the appliances' power consumption does not exceed the value speci-
fied in the above chart.

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS

When a long electric extension cord is used to connect an appliance or tool with
the generator, a certain amount of voltage drop occurs in the extension cord which
lessens the effective voltage available to 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.
