Check the appliance or tool nameplates for the current and
voltage to insure compatibility. Remember that power taken
from receptacle C reduces the power available at both A and
B. Any remaining 120 volt loads should be equally divided
between A and B. Failure to split the load will cause
permanent damage to the stator. Although circuit breakers
are provided, damage due to overloading constitutes abuse
and will not be warranted.
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 current to start them
as to run them. Capacitor motors are easier to start and
usually require 2 to 4 times as much current to start them as
to run them. Repulsion Induction motors are the easiest to
start and usually require 1 1/2 to 2 1/2 times as much to start
them as to run them.
Most fractional horsepower motors take about the same
amount of current to run them whether they are of Repulsion-
Induction (RI), Capacitor (Cap), or Split-Phase (SP) type.
The chart below shows the approximate current required to
start and run various types and sizes of 120 volt 60 cycle
electric motors under average load conditions.
RUNNING STARTING AMPS
HP AMPS SP CAP RI
1/6 3.2 16 TO 22 6 TO 13 5 TO 8
1/4 4.5 22 TO 32 9 TO 18 7 TO 12
1/3 5.2 26 TO 35 10 TO 21 8 TO 17
1/2 7.2 NOT MADE 14 TO 29 11 TO 18
1 13.0 NOT MADE 26 TO 52 20 TO 33
The figures given above are for an average load such as a
blower or fan. 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-excited generators respond to severe overloading
differently than the power line. 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 DAMAGING THE
GENERATOR STATOR AS WELL AS THE MOTOR
WINDING.
Because 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.
INTENDED USES
These engine generator sets have been designed primarily
for portable use. Both 120 and 240 volt AC receptacles are
provided in the 'control panel' to plug in your loads (lights,
portable tools, and small appliances). These units are dual
wound generators, therefore the 120 Volt loads must be
equally split with 1/2 of the rated capacity available on
each of the two 120 Volt circuits. See unit capabilities for
further explanation.
These portable units require large quantities of fresh air for
cooling of both the engine and the generator. Fresh air is
drawn from both the engine end and the generator end and
is exhausted at the center of the unit. For safety, long life
and adequate performance, these units should never be
run in small compartments without positive fresh air flow.
RESTRICTED USES
DO NOT remove from the cradle assembly. Removal of
the generator from the cradle assembly may cause
excessive vibration and damage to the engine generator
set.
DO NOT install and operate these portable generators in a
small compartment., i.e. generator compartment of
vehicles, motor homes or travel trailers. These
compartments will not allow enough free flow fresh air to
reach the engine generator set for cooling and will cause
the unit to overheat damaging both the engine and the
generator. Small compartments will also develop hot spots
where there is very little air flow and may cause a fire.
DO NOT attempt to operate at 50 cycles. These units are
designed and governed to operate at 60 cycles only.
UNIT CAPABILITIES
Generator Connections - The diagram below represents a
typical 5400 watt generator. Receptacles A and B are the
two 120 Volt duplex receptacles. Up to 2700 watts at 120
volts (22.5 Amps) can be taken from the generator at each
of the receptacles. This generator produces 120 and 240
volt, 60 Hz (Hertz), AC (Alternating Current).
CAUTION: EQUIPMENT DAMAGE
CAUTION MUST BE EXERCISED TO PREVENT
OVERLOADING EITHER OF THE GENERATORS
120 VOLT OUTPUT CIRCUITS (A OR B).
