EXTENSION
CORDS
Only use grounded extension cords. Be sure
to use extension cord with proper wire gauge
size. See chart below.
Recommended Minimum Wire
Gauges (AWG) for Extension
Cords
WARNING: For a grounding
point, do not use metal pipe be-
ing used to carry combustible
materials or gases.
Grounding generator helps prevent electric
shock from a ground fault condition. Locate
ground lug on roll cage (see Figure 12).
Attach a #10 stranded-copper ground wire
to ground lug. Drive grounding point into
ground. Grounding point can be a stake,
grounding rod, or pipe. Grounding point
should be copper or brass. Attach ground
wire to grounding point. You must supply
the ground wire and grounding point. These
do not come with generator. Follow the
National Electrical Code
and all state and
local codes. Consult your power company
or a licensed electrician.
WARNING: You must properly
earth-ground generator before
starting. This will help guard
against deadly electric shock. Only
use grounded plugs with genera-
tor. Only use grounded extension
cords. Only use three-wire or
double-insulated power tools.
STANDBY
INSTALLATION
TO HOME OR
BUILDING
WARNING: The electrician
must install a double-throw
transfer switch. This isolates ex-
isting electrical circuits from the
utility power line. If not isolated,
generator output will back-feed
into utility power line. This may
electrocute a power company line
repair person.
IMPORTANT: This generator will not
power your entire home. Most home utility
electric service is more than 60 amps. This
will exceed generator output. Only power
needed items during a power outage. Make
sure total wattage of electrical load does not
exceed rated wattage of generator.
You may need to use this generator as a
standby power source. During a power out-
age, the generator will power selected items
in a building. Have generator and additional
wiring installed by a skilled, licensed electri-
cian. This is not a do-it-yourself job. Follow
all local codes.
WARNING: Have standby in-
stallation performed by a skilled,
licensed electrician. Do not let
anyone else wire into a utility
circuit. Personal injury, equip-
ment damage, or damage to home
could occur.
