CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within the generator and
receptacle nameplate rating. Overloading may cause
damage to the generator and/or the loads .
Most electric tools and appliances will have the volt-
age and amperage requirements on their individual
nameplates. When in doubt, consult the manufacturer
or a local electrician. The nameplate amperage rating
for electric motors can be misleading. See “Starting
Electric Motors” in Unit Capabilities (page 4).
These engine-generator sets are inherently self regu-
lating based on engine speed. The engine governor
will automatically adjust itself to the load. No harm
to the generator will result if it is operated with no
load connected. Proper utilization of the receptacles
located on the control panel is necessary to prevent
damage to either the receptacles or the generator.
The generator is a limited source of electrical power,
therefore, pay special attention to the receptacle
and generator ratings. The nameplate rating can be
obtained through a single receptacle as long as the
receptacle amperage rating is not exceeded.
GROUNDING
All units must be grounded. Drive a 3/4 or 1” copper
pipe or rod into the ground close to the engine-gen-
erator set. The pipe must penetrate moist earth. Con-
nect an approved ground clamp to the pipe. Run a
no. 10 Awg wire from clamp to the generator ground
lug on the receptacle panel. Do not connect to a
water pipe or to a ground used by a radio system.
The engine-generators covered in this manual were
designed primarily for portable use. If you are con-
necting into a building wiring system that is already
grounded using the 14-60 4 wire plug, you do not
have to ground the unit.
WARNING: PERSONAL DANGER
DO NOT OPERATE THIS GENERATOR INDOORS.
The unit should be stored in a warm dry location.
During a power outage, move the unit outdoors to a
flat dry location such as a driveway or sidewalk
.
WIRING
Plug your tools such as drills, saws, blowers, sump
pump and other items to be powered directly into
the generator receptacles. Before plugging in all
the tools and cord sets, recheck the rating of the
generator set. Be sure it can handle the intended
load and is compatible with the voltage, phase, and
current ratings. ‘Hard Wiring’ this unit directly into
a home or a temporary construction site electrical
system is
NOT A SIMPLE DO-IT-YOURSELF JOB.
For your safety, all wiring must be done by a quali-
fied electrician and conform to the National Electric
Code and comply with all state and local codes and
regulations. Check with local authorities before
proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole double throw manual
transfer switch must be installed any time a genera-
tor is being connected to an existing distribution
system.
1. These engine generator sets are designed for
portable use. Receptacles are provided on the
control panel to permit 120 volt portable appliances
and tools to be plugged directly into them. Please
note that the 4-wire 120/240 volt receptacle on these
units are designed to power both 120 or 240 volt
loads. The plug for this receptacle can be wired for
either 120 volt, 240 volt, or a combination of 120 and
240 volt loads depending on how the plug is wired.
A 4-wire receptacle (two hot, one ground, and one
neutral) has been provided on the control panel
for use in temporary power applications requiring
120/240 volt power. Consult a licensed electrician
for wiring the TemPower plug and connecting it as
temporary service. To connect these units directly to
an un-powered, isolated construction site TemPower
panel, have your electrician connect to the control
panel using a 120/240 volt, 4-wire twist-lock plug
(L14-30P).
2. If the generator set is be connected to an existing
distribution system, a fully isolated manual trans-
fer switch must be installed. The transfer switch
prevents damage to the generator and other circuit
components if main line power is restored while the
generator is connected. Installing a transfer switch
also permits the use of normal fusing.
