GP 4000 Operation
4.4 Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances running at
120 VAC or 240 VAC. Check the nameplate or label provided on tools and
appliances to make sure their power requirements match the power output of the
generator.
Some appliances and tools require a surge of current when starting. This means
that the amount of power needed to initially start the equipment is larger than the
power required to keep it running. The generator must be capable of supplying this
“surge” current. Other types of appliances require more power than is actually
stated on their nameplate.
The information in “Approximate Starting Power Requirements” is offered only as a
general guideline to help you in determining power requirements for different types
of equipment. Check with your nearest Wacker Neuson dealer, or contact the
manufacturer or dealer of the tool or appliance, with questions regarding its power
requirements.
NOTICE: If a tool or appliance does not reach full speed within a few seconds
when switched on, turn it off immediately to avoid damage.
Approximate
Starting
Power
Requirements
„
Incandescent lights and appliances such as irons and hot plates, which use a
resistive-type heating element, require the same wattage to start and run as is
stated on their nameplates.
„
Fluorescent and mercury lamps require 1.2–2 times their stated wattage to start.
„
Electrical motors and many types of electrical tools often require a large starting
current. The amount of starting current depends on the type of motor and its
use.
„
Most electrical tools require 1.2–3 times their stated wattage for starting.
„
Loads such as submersible pumps and air compressors require a very large
force to start. They need as much as 3–5 times the wattage stated on the
nameplate in order to start.
If the wattage is not given for a particular tool or appliance, it can be calculated by
multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS
