NOTE:
¡ The data shown above is only a guideline for
approximate load capacities, from generator
model to generator model, with different types of
loads at rated outputs. These values may be
different from actual applications because of the
output characteristics peculiar to each load. Note
that the starting current is not taken account of in
these approximate values.
¡ Connecting a motor.
When connecting to a line starting motor, these
generators may be used to start a submerged
pump of 5.5kW, 7.5kW, 11.0kW (three-phase).
When starting the motor, the voltage drops
immediately. The circuit may be opened if an
electromagnetic switch is connected to the same
circuit. When connecting two motors or more,
make sure the total current capacity of the motors
does not exceed the total rated current.
¡ Connecting to lights and electric heaters.
When connecting to lights or electric heaters, the
generator can be used up to the rated capacity.
When using a single phase, it can be used up to the
rated current.
¡ The power factor is used to determine input of the
electrical devices.
AC devices
Electric power (W)
= Voltage (V) x Current (A) ÷ Power factor
Power factors of commonly used devices are listed in
the following table.
Power factor
Single-phase induction motor
AC arc welder
Fluorescent lighting and indoor
incandescent lighting
Outdoor incandescent light
and heaters
0.4 to 0.6

¡ Ordinarily, a motor is rated in kW. This does not
refer to motor output.
Motor input kVA
=
Motor output (HP)
Motor efficiency x power factor x 1.34
NOTE:
¡ If a lighting system is employed together with
some types of computers and inverter air-
conditioners and/or the regulated power supply
for TV sets, the lights might suffer flickering. This
phenomenon is not a trouble of the generator: it is
caused by poor matching between the above-
mentioned regulated power supply and the
generator's automatic voltage regulator. In such a
case, modify the load combination and make sure
no flickering appears any longer.
