INSTALLATION TO
HOME OR
BUILDING
WARNING: The electrician
must install a double-throw trans-
fer switch. This isolates existing
electrical circuits from the utility
power line. If not isolated, gen-
erator output will back-feed into
utility power line. This may elec-
trocute 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 elec-
trician. This is not a do-it-yourself job. Fol-
low 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.

Grounding generator helps prevent electric
shock from a ground fault condition. Follow
these steps to ground your generator:
1. Locate ground bolt on generator hous-
ing (see Figure 11).
2. Loosen SEM nut on ground bolt.
Note:
Do not remove SEM nut from bolt.
3. Attach a spade connector to the end of
a #10-8 stranded-copper ground wire.
4. Attach spade connector to ground bolt
between flat washer and SEM nut (see
Detail A in Figure 11).
5. Drive grounding point into ground.
Note:
Grounding point can be a stake,
grounding rod, or pipe. Grounding
point should be copper or brass.
6. Attach ground wire to grounding point.
WARNING: You must prop-
erly earth-ground generator be-
fore starting. This will help guard
against deadly electric shock.
Only use grounded plugs with
generator. Only use grounded ex-
tension cords. Only use three-wire
or double-insulated power tools.
