EXTENSION CORD CABLE SIZE
Refer to the table below to ensure the cable size of the extension cords you use are capable of carrying the required load.
Inadequate size cables can cause a voltage drop, which can burn out the appliance and overheat the cord.

ELECTRIC MOTOR LOADS
It is characteristic of common electric motors in normal operation to draw up to six times their running current while starting.
This table may be used to estimate the watts required to start electric motors; however, if an electric motor fails to start or
reach running speed, turn off the appliance or tool immediately to avoid equipment damage. Always check the requirements
of the tool or appliance being used compared to the rated output of the generator.

NOTICE:
Operating voltage and frequency requirement of all
electronic equipment should be checked prior to plugging
them into this generator. Damage may result if the
equipment is not designed to operate within a +/- 10%
voltage variation, and +/- 3 hz frequency variation from the
generator name plate ratings. To avoid damage, always
have an additional load plugged into the generator if
solid state equipment (such as a television set) is used.
A power line conditioner is recommended for some solid
state applications.

GENERATOR CAPACITY
Make sure the generator can supply enough continuous (run-
ning) and surge (starting) watts for the items you will power
at the same time. Follow these simple steps.
1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items. This
is the amount of power the generator must produce to
keep the items running. See the wattage reference chart
at right.
3. Estimate how many surge (starting) watts you will need.
Surge wattage is the short burst of power needed to start
electric motor-driven tools or appliances such as a circular
saw or refrigerator. Because not all motors start at the
same time, total surge watts can be estimated by adding
only the item(s) with the highest additional surge watts to
the total rated watts from step 2.
