1.8 Determining Power
Requirements
This generator is designed to operate single-phase,
60 Hz appliances running at 120 VAC. Check the name-
plate 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 ìsurgeî current. Other types of
appliances require more power than is actually stated on
their nameplate.
The chart below is offered only as a general guideline to
help you in determining power requirements for different
types of equipment. Check with your nearest WACKER
Dealer, or contact the manufacturer or dealer of the tool
or appliance, with questions regarding its power require-
ments.
1.9 Outdoor Installation
Place the generator in an area where it will not be
exposed to rain, snow or direct sunlight. Make sure it is
positioned on firm, level ground so it will not slide or shift.
Position engine exhaust away from areas where people
may be present.
If operating the generator inside a tunnel or deep trench,
make sure there is adequate ventilation. Precautions
similar to those required when operating indoors may be
necessary.
The surrounding area must be free from water and
moisture. All components must be protected from exces-
sive moisture.
1.10 Indoor Installation
If the generator must be installed indoors, adequate
ventilation or exhaust hoses must be provided. When
venting exhaust fumes, make sure the exhaust piping is
large enough to prevent excessive back pressure to the
engine. Back pressure reduces engine efficiency and
may cause the engine to overheat.
- 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 ñ 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 ñ 3 times their
stated wattage for running.
- Loads such as submersible pumps and air com-
pressors require a very large force to start. They
need as much as 3 ñ 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:
VOLTS X AMPS = WATTS
CAUTION: If a tool or appliance does not reach full
speed within a few seconds when switched on, turn it off
immediately to avoid damage.
Exhaust fumes contain carbon monoxide and are
extremely poisonous!
