Grounding Point
Figure 13 - Grounding Generator
(MGH8500AIE Shown)
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. Follow
these steps to ground your generator:
1. Locate ground lug on generator housing
(see Figure 13).
2. Loosen SEMS nut on ground lug. Note:
Do not remove SEMS nut or set screw
from ground lug.
3. Attach a spade connector to #10-8
stranded-copper ground wire. Place
spade connector on ground bolt between
flat washer and SEMS nut. Tighten
SEMS nut (see Detail A, Figure 13).
4. Drive grounding point into ground.
Note: Grounding point can be a stake,
grounding rod, or pipe. Grounding
point should be copper or brass.
5. Attach ground wire to grounding
point.
You must supply the ground wire and ground-
ing 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 prop-
erly earth-ground generator be-
fore 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.
