6. WATTAGE INFORMATION
22
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 5,000 watt generator can power a 1800 to 4000 watt electrical
tool.
Loads such as submersible pumps 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 1,000 to 1,700 watt
pump.
NOTE :
The following wattage chart is general guide only. Refer to your specific appliance for
correct wattage.
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.
