Generally, the power rating of an electrical appliance indicates the amount of work that can be done by it.
The electric power required for operating an electrical appliance is not always equal to the output wattage
of the appliance. The electrical appliances generally have a label showing their rated voltage, frequency,
and power consumption (input wattage). The power consumption of an electrical appliance is the power
necessary for using it. When using a generator for operating an electrical appliance, the power factor and
starting wattage must be taken into consideration.
In order to determine the right size generator, it is necessary to add the total wattage of all appliances to
be connected to the unit.
Refer to the followings to calculate the power consumption of each appliance or equipment by its type.
(1) Incandescent lamp, heater, etc. with a power factor of 1.0
Total power consumption must be equal to or less than the rated output of the generator.
Example : A rated 3000W generator can turn thirty 100W incandescent lamps on.
(2)
Fluorescent lamps, motor driven tools, light electrical appliances, etc. with a smaller power factor
Select a generator with a rated output equivalent to 1.2 to 2 times of the power consumption of the
load. Generally the starting wattage of motor driven tools and light electrical appliances are 1.2 to 3
times lager than their running wattage.
Example : A rated 250 W electric drill requires a 400 W generator to start it.
NOTE 1: If a power factor correction capacitor is not applied to the fluorescent lamp, the more power
shall be required to drive the lamps.
NOTE 2: Nominal wattage of the fluorscent lamp generally indicates the output wattage of the lamp.
Therefore, if the fluorescent lamp has no special indication as to the power consumption,
efficiency should be taken into account as explained in ltem (5) on the following page.
(3) Mercury lamps with a smaller power factor
Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
Example : A 400 W mercury lamp requires 800 W to 1200 W power source to be turned on. A rated
3000 W generator can power two or three 400 W mercury lamps.
(4) Initially loaded motor driven appliances such as water pumps, compressors, etc.
These appliances require large starting wattage which is 3 to 5 times of running wattage.
Example : A rated 900 W compressor requires a 4500 W generator to drive it.
NOTE 1: Motor-driven appliances require the aforementioned generator output only at the starting.
Once their motors are started, the appliances consume about 1.2 to 2 times their rated power
consumption so that the excess power generated by the generator can be used for other
electrical appliances.
NOTE 2: Motor-driven appliances mentioned in items (3) and (4) vary in their required motor starting
power depending on the kind of motor and start-up load. If it is difficult to determine the
optimum generator capacity, select a generator with a larger capacity.
3. RANGE OF APPLICATIONS
Page 11
– 8 –
(4) Appliances without any indication as to power consumption
Some appliances have no indication as to power consumption; but instead the work load (output) is
indicated. In such a case, power consumption is to be worked out according to the numerical formula
mentioned below.
Efficiencies of some electrical appliances are as follows :
Single-phase motor . . . . . .0.6 to 0.75 (The smaller the motor, the lower the efficiency)
Fluorescent lamp . . . . . . . .0.7 to 0.8
Example 1: A 40W fluorescent lamp means that its luminous output is 40W. Its efficiency is 0.7 and
accordingly, power consumption will be 40÷0.7= 57W. As explained in Item (2), multiply this
power consumption value of 57W by 1.2 to 2 and you will get the figure of the necessary
capacity of a generator. In other words, a generator with a rated output of 1000W capacity
can light nine to fourteen 40W fluorescent lamps.
Example 2
: Generally speaking, a 400W motor means that its work load is 400W. Efficiency of this motor
is 0.7 and power consumption will be 400÷0.7= 570W. When this motor is used for a
motor-driven tool, the capacity of the generator should be multipled by 1.2 to 3 and 570W as
explained in the ltem (3).
The power consumption of electrical appliances is shown below for reference, use this as a measuring
guide when choosing electrical appliances and which generator to use.

NOTES : Wiring between generator and electrical appliances
1. Allowable current of cable
Use a cable with an allowable current that is higher than the rated input current of the load (electrical
appliance). If the input current is higher than the allowable current of the cable used, the cable will
become excessively heated and deteriorate the insulation, possibly burning it out. The table below
shows cables and their allowable currents for your reference.
2. Cable length
If a long cable is used, a voltage drop occurs due to the increased resistance in the conductors
decreasing the input voltage to the load (electrical product). As a result, the load can be damaged.
The table below shows voltage drops per 30 meters of cable.

4-3) MEASURING INSULATION RESISTANCE
4-2) AC OUTPUT MEASURING
Use a circuit above for measuring AC output. A hot plate or lamp with a power factor of 1.0 may be used as a
load. Adjust the load and rpm, and check that the voltage range is as specified in the following table at the
rated amperage and rated rpm.
Before checking insulation resistance, be sure to short-
circuit the terminals of an AC receptacle using a wire to
discharge the electricity remained in the circuit.
(1)
Connect the megger tester across either one of the two
output terminals of the AC receptacle and ground
terminal to measure the insulation resistance.
Measure it with the AC breaker on. An insulation
resistance of 1 MΩor more is normal.
(Original insulation resistance at the time of shipment
from the factory is 10 MΩor more.)
If it is less than 1 MΩ, disassemble the generator and
measure the insulation resistance of the stator, rotor
and control panel individually.

(2) ALTERNATOR
Check the insulation resistance between the three
(Red,Blue and White) wires of the stator and the
generator body as shown in the figure right.
If there is a wire which has insulation resistance less
than 1 MΩ, replace the stator. Insulation failure
cause electrical leak which may result in
electrocution.
(3) CONTROL PANEL
Before checking, disconnect the inverter unit from
the control panel.
Measure the rechargeable parts (where the electric
current flows) and insulation resistance between the
live parts and the ground terminal. Measure with the
AC breaker on. If there is a spot where insulation
resistance less than 1 MΩ, replace the part.
Insulation failure may result in electrification, or an
electrical leak.

(2)INVERTER UNIT
Check if there is no color change or blister on the
filling resin, and confirm that there is no damage or
color change in the electrical parts, electrical wires,
or the connectors.
And, check the resistance at the 2P connector for
AC output and at the 4P connecter for the stator
wire terminals.
4-4) CHECKING FUNCTIONAL MEMBERS
(1)STATOR
Measure the winding wire resistance. Check the
resistance of the wires that comes out from the
stator using a tester, referring to the following table.
NOTE: When measuring according the numerical value
shown in the chart, tolerance should be
considered because the inaccuracy of the tester.
If an accurate value is needed, measure by
electric resistance using an Ohm-meter.
While doing this, use caution to avoid contact
resistance.
