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.

EXTENSION CORD
See Figure 1.
The generator is supplied with a 25 ft. 12 GA SJTW 4- conductor
105ºC extension cord. This cord is equipped with an L14-
30P twist-lock plug on one end which plugs directly into the
corresponding twist-lock receptacle on the control panel of
the generator. The opposite end has four 5-20R receptacles
that can be used to power individual loads. NOTE: For 120
volt use only. Make sure the loads do not exceed the 20
amp rating of the extension cord. Circuit breaker protection
is provided on the extension cord.
The receptacles on the extension cord are color coded to
match corresponding circuit breakers. When several loads
are powered at the same time, it is best to keep equal loads
supplied to each separately colored receptacle if possible.
Each receptacle of the connector is capable of sustaining 20
amps of current provided the generator is capable of supply-
ing 4800 watts of power. Check nameplate ratings for total
wattage capability of the generator.

NOTICE:
Operating voltage and frequency requirement of all
electronic equipment should be checked prior to plug-
ging 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, al-
ways 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.
