APPLIANCE LOADS
PT-3000 maybe used to supply AC voltage for appliances. With the exception of
a resistance-type load such as a heating element, requirements for appliances are usually
low. However, such loads must not be overlooked when calculating the total wattage
requirements. To avoid an overload situation, reserve capacity should also be calculated
for unanticipated appliance loads. The average power requirements for some common
electrical appliances are listed below as a guide.

EXTENSION CORDS
An extension cord is normally used to provide electrical power from the APU to a
remote location. The extension cord size (AWG#) and length must be adequate to safely
maintain the amperage requirements. A proper size extension cord will help minimize the
voltage drop between the APU and remote location.
