DON’T OVERLOAD THE
GENERATOR
NOTE: Refer to this section when you are using the
generator without the Power Transfer System. Refer to
the Power Transfer System owner’s manual when operating
the generator in conjunction with the Power Transfer
System. Ask your Power Transfer System installer to review
load management techniques.
Overloading a generator in excess of its rated wattage
capacity can result in damage to the generator and/or
connected electrical devices. Observe the following, to
prevent overloading the unit:
• Add up the total wattage of all electrical devices to be
connected at one time.This total should NOT be greater
than the generator’s wattage capacity.
• If the appliance, tool or motor does not give wattage,
multiply 120 Volts times ampere rating to determine
watts (volts x amps = watts).
• The rated wattage of lights can be taken from wattage
listed on the light bulbs.The rated wattage of tools,
appliances and motors can usually be found on a data
plate or decal affixed to the device. Use Figure 13 below
as a general reference.
• Some electric motors, such as induction types, require
about three times more watts of power for starting than
for running.This surge of power lasts for only a few
seconds when starting such motors. Be sure you allow
for this high starting wattage when selecting electrical
devices to connect to your generator. First figure the
watts needed to start the largest motor. Add to that
figure the running watts of all other connected loads.
