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 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. Dur-
ing 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 genera-
tor set. Be sure it can handle the intended load and
is compatible with the voltage, phase, and current rat-
ings. ‘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 qualified 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 generator
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 10 and
40 volt portable appliances and tools to be plugged
directly into them. Please note that the 3-wire 40
volt receptacle(s) on these units are designed to
power only 40 volt tools. There are two hot leads
and a ground wire, but no neutral connection, in the
3-wire 40 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 ap-
plications requiring 10/40 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 plug (14-60P).
NOTE: Never attempt to use the 40 volt three wire
receptacle to wire into a building.
. 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.
3. Many homes and construction sites are wired
for at least 60 to 100 Amp entrance service, much
greater than the capacity of this portable genera-
tor. When installing the generator at these sites, a
secondary emergency distribution panel may have to
be installed, such as the Emergency Transfer/Service
(ET/S) system available through your WINCO dealer.
The emergency distribution panel must be installed
by a licensed electrician according to all applicable
codes. The electrician will move the critical circuits
to be powered during the outage to the emergency
panel. Keep in mind only a limited amount of amper-
age is available from the generator set. Some circuit
breakers may still have to be turned off to prevent an
overload on the generator during the initial start up.
See the nameplate on your generator for the amper-
age capabilities of your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load ap-
plied to the generator will cause the generator to
produce low voltage and may damage the engine
generator set. It may also cause severe damage to
the loads connected to the generator at that time. Im-
proper loading of the generator set constitutes abuse
and will not be covered by warranty.
