Installation (Continued)
For a grounding
point, do not use
metal pipe being used to carry combus-
tible materials or gases.
electrical load does not exceed rated
wattage of generator.
You can use this generator as a standby
power source. During a power outage, the
generator will power selected items in a
building. Have generator and additional
wiring installed by a skilled, licensed
electrician. This is not a do-it-yourself job.
Follow all local codes.
The electrician
must install a
double-throw transfer switch. This
isolates existing 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.
DUST, DIRT, RAIN, AND SNOW
Do not use genera-
tor outdoors in
rain or snow. Do not use generator near
standing water or snow. Do not use if
generator is wet or damp. Operating
generator in these conditions increases
the risk of electrocution. Severe injury
or death can occur.
Do not use generator in extremely dusty or
dirty conditions. This will severely affect its
life. Keep generator clean. Do not allow
dust, dirt, rain, or snow to collect on it.
Protect generator from outdoor elements.
EXTENSION CORDS
Only use grounded extension cords. Be
sure to use extension cord with proper
wire gauge size. See chart in next column.

GROUND FAULT PROTECTION
Ground Fault Circuit Interrupter (GFCI)
helps guard against electric shock. On
construction sites, you must use a GFCI.
OSHA and the National Electric Code
requires this.
You must provide the GFCI device.
Purchase GFCI at any electrical supply
house. Check the Yellow Pages for the
nearest supply house.

STANDBY INSTALLATION TO HOME OR
BUILDING
Have standby
installation
performed by a skilled, licensed
electrician. Do not let anyone else wire
into a utility circuit. Personal injury,
equipment damage, or damage to
home could occur.
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

DETERMINING ELECTRICAL LOAD FOR
GENERATOR
You must decide what electrical load your
generator can power. Do this before using
generator. Use the following four-step
method. It will help you select a load that
is not too large. Make sure total wattage
of all electrical loads does not exceed
rated wattage of generator. For rated
wattage of your generator, see Electrical
Specifications, page 2. Electric motors
present a special problem when figuring
load. Read Step 3 carefully.
1. Make two lists of items you want
powered by generator. List all motors
and motor powered appliances in
one. List all lights, small appliances,
etc. in the other. For standby service
to home or building, only include
items you must power.
2. Enter running watts of each item except
motors. The light bulb or appliance
nameplate lists its wattage. Remember,
1KW = 1000 watts.
