WATTAGE INFORMATION:
Some appliances need a "Surge" of energy when starting. This is commonly known as a
"LAGGING" Load.
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 branch with questions regarding power surges 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 their use. This is commonly known as a "LEADING" Load.
Loads such as fluorescent lamps require1.5 to 2 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 "Power" is attained to start the motor, the appliance will require only
+-50% of the wattage in order to continue running.
Most electrical tools require 1.5 to 3 times their wattage for running under load during use. 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.
