SCOPE OF APPLICABILITY
Some appliances need a "surge" of energy when starting.
This means that the amount of electrical power needed to start the appliance may exceed the amount
needed to maintain its use.
Electrical appliances and tools normally come with a label indicating voltage, cycles/Hz, amperage
(amps) and electrical power needed to run the appliance or tool.
Check with your nearest dealer or service center with questions regarding power surge of certain
appliances or power tools.
• Electrical loads such as incandescent lamps and hot plates require the same wattage to start as is
needed to maintain use.
• Loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during start-up.
• Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
• Electrical motors require a large starting current. Power requirements depend on the type of motor
and its use. Once enough "surge" is attained to start the motor, the appliance will require only
50% to 30% of the wattage to continue running.
• Most electrical tools require 1.2 to 3 times their wattage for running under load during use. (For
example, a 9,000 watt generator can power a 3,200 to 7,000 watt electrical tool.)
• Loads such as submersible pumps, air conditioners and air compressors require a very large force
to start. They need 3 to 5 times the normal running wattage in order to start. (For example, a 5,000
watt generator would only be able to drive a 1,800 to 3,100 watt pump.)
• If the power consumption of electrical appliances exceeds the operating range or if there is short
circuit or other problems in the appliances, the AC breaker could trip "OFF" or the rotation of the
generator could be abnormally reduced. In this case, stop the generator to see if the power
consumption of the appliances is too large and if there is a problem in the appliances.
• The frequency (the number of the generators rotation) was adjusted before the time of shipment.
Changing the frequency could result in the generators breakdown, so refrain from changing it.
To determine the total wattage required to run a particular electrical appliance or tool, multiply the
voltage figure of the appliance/tool by the amperage (amps) figure of same. The voltage and
amperage (amps) information can be found on a name plate which is normally attached to electrical
appliances and tools.
Applications
Incandescent lamp, Heater
Fluorescent lamp, Electric tool
Pump, Compressor
WARNING:
HITACHI electronic controlled products should not be used with portable
generators.
Irregular generator power could cause these products to fail.
Regarding other manufacturer's products, please contact the manufacturer to see
if it is safe to use the electronic controlled products with portable generators.
NOTE:
The above wattage chart is general guide only. Refer to your specific appliance for correct
wattage.
When you use two or more alternating current outlets at a time, be careful that the sum of
the appliances' power consumption does not exceed the value specified in the above chart.
