6. WATTAGE INFORMATION
21
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.
