ELECTRIC MOTOR LOADS

It is characteristic of common electric motors in normal operation to draw up to six times their running current while start-
ing. This table may be used to estimate the watts required to start “Code G” 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.

CAUTION

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.

ELECTRICAL

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.
