WATTAGE INFORMATION
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 centre 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 40000 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.
