Wattage Information; Voltage Drop In Electric Extension Cords - Makita EG-Serie Bedienungsanleitung

5. 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 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 À uorescent 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 speci¿ c appliance for correct wattage.
To determine the total wattage required to run a particular electrical appliance or tool, multiply the voltage ¿ gure of
the appliance/tool by the amperage (amps) ¿ gure of same. The voltage and amperage (amps) information can be
found on a name plate which is normally attached to electrical appliances and tools.
Incandescent lamp, Heater
Fluorescent lamp, Electric tool
Mercury lamp
Pump, Compressor

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS

When a long electric extension cord is used to connect an appliance or tool to the generator, a certain amount of
voltage drop or loss occurs in the extension cord which reduces the effective voltage available for the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when an extension cord of 300 feet
(approx. 100 meters) is used to connect an appliance or tool to the generator.
