UNIT CAPABILITIES
GENERATOR CONNECTIONS
The diagram below represents this 15,000 watt (rated output)
generator. A & B represent the 120 volt output legs of this generator.
Up to 7500 watts at 120 volts (45 Amps) can be drawn from the
receptacles attached to either A or B output legs. This generator is
capable of producing 62.5 Amps of 240 volt current at C. Check the
appliance or tool nameplates for the current and voltage to insure
compatibility. Remember that power taken from C reduces the power
available at equally both A and B and vice versa.
Check the appliance or tool nameplates for the current and voltage
to ensure compatibility. Remember tha power utilized from C reduces
the power available from both A and B and vice versa. The EC22000
utilizes the same format with A and B being 9500 Watts and C being
19,000 Watts.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps) to start them than to
run them. Some motors, particularly low cost split-phase motors, are
very hard to start and require 5 to 7 times as much starting current as
running current. Capacitor motors are easier to start and usually require
2 to 4 times as much starting current as running current. Repulsion
Induction motors are the easiest to start and require only 1 1/2 to 2 1/2
times as much starting as running current.
Most fractional horsepower motors take about the same amount
of current to run them whether they are Repulsion Induction (RI),
Capacitor (Cap), or Split-Phase (SP) type.
If the electric motor is connected to a hard starting load such as an air
compressor, it will require more starting current. If it is connected to a
light load, or no load such as a power saw, it will require less starting
current. The exact requirement will also vary with the brand or design
of the motor.
Self-exciting generators respond to severe overloading differently than
utility power. When overloaded, the engine is not able to supply enough
power to bring the electric motor up to operating speed. The generator
responds with high initial starting current, but the engine speed drops
sharply. The overload may stall the engine. If allowed to operate at very
low speeds, the electric motor starting winding will burn out in a short
time. The generator winding might also be damaged.
CAUTION: EQUIPMENT DAMAGE
Running the generator set under these conditions may result in
damage to the generator stator as well as the motor winding.
The heavy surge of current required for starting motors is required for
only an instant. The generator will not be damaged if it can bring the
motor up to speed in a few seconds of time. If difficulty is experienced
in starting motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL. Failure to maintain
the engine oil at the proper level will result in serious engine damage.
When you unpack your engine-generator set be sure to remove all the
information sheets and manuals from the carton.
1. As you receive your unit, it is critical to check it for any damage. If
any damage is noted, it is always easiest to refuse the shipment and
let WINCO take care of the freight claim. If you sign for the unit, the
transfer of the ownership requires that you file the freight claim
2. Before proceeding with the preparations of your new generator
for operation, take a couple of minutes to ensure the unit you have
received is the correct model and review the specification pages in this
manual to ensure that this unit meets your job requirements.
VENTILATION
These engine generator sets use large amounts of fresh air for cooling.
When designing plans for your installation, special attention must be
paid to the flow of hot air from both the engine and the generator.
Both the engine and the generator must be supplied with a constant
flow of fresh air from the outside to ensure they don’t overheat. Some
provision must be made to remove the hot air out the enclosure.
Ambient temperature around the unit should not exceed 122°F.
Engine or generator failures resulting from inadequate ventilation
are considered abuse and not covered by the generator or engine
manufacturer’s warranty.
The engine exhaust from this engine must be vented to the outside.
When venting hot exhaust through any type of flammable wall be sure
to use exhaust thimbles to prevent fires.
WARNING:
Failure to properly vent out the exhaust out of an enclosure can and will
kill you. Carbon monoxide is both invisible and orderless, it can build up
very rapidly in any enclosure not properly vented.
