will permit the engine to work more effi ciently when
the load is applied and will reduce the wear in the
engine, extending its life.
Receptacles have been provided to allow loads to
be connected to the generator. The loads should
be added one at a time. If a large motor is being
started or multiple motors are being started, they
should be started individually and the largest should
be started fi rst.
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 manufac-
turer 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 reg-
ulating 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” cop-
per pipe or rod into the ground close to the engine-
generator set. The pipe must penetrate moist earth.
Connect 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 sys-
tem.The engine-generators covered in this manual
were designed for portable use. 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 fl at 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
temporary construction site electrical system is NOT
A SIMPLE DO-IT-YOURSELF JOB. For your safety
all wiring must be done by a qualifi ed electrician and
conform to the National Electric Code and com-
ply 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 heavy duty commercial use. Receptacles
are provided on the control panel to permit 120 and
240 volt portable appliances and tools to be plugged
directly into them. Please note that the 3-wire 240
volt receptacle(s) on these units are designed to
power only 240 volt tools. There are two hot leads
and a ground wire, but no neutral connection, in the
3-wire 240 volt receptacle. 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). The
use of locking receptacles and locking plugs pro-
vides the convenience of quick disconnect, for mov-
ing, while allowing workers to safely reconnect the
power. In addition they prevent the plug from being
accidentally removed by bumping or vibration.
2. If the generator set is be connected to 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.
3. Many homes and construction sites are wired
for at least 60 to 100 Amp entrance service, much
greater than the capacity of these portable genera-
tors. When installing the generator at these sites, a
secondary emergency distribution panel may have
to be installed, such as the Emergency Transfer/Ser-
vice (ET/S) system available through your WINCO
dealer. The emergency distribution panel must be
