Operation
4.4 Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances running at
120 and 240 VAC.
NOTICE: Do not exceed the continuous rated output of the generator. Damage to
tools or generator will occur. See Technical Data.
Check the nameplate or label provided on tools and appliances to make sure their
power requirements are met by the power output of the generator. If the wattage is
not given for a particular tool or appliance, contact the tool manufacturer for
wattage requirements.
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 determine power requirements for different types of
equipment. Check with your nearest Wacker dealer, or contact the manufacturer or
dealer of the tool or appliance, if you have questions regarding power
requirements.
Approximate Incandescent lights and appliances such as irons and hot plates, which use a

starting power
resistive-type heating element, require the same wattage to start and run as is
requirements
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
Three Phase: VOLTS x AMPS x 1.732 x 0.8 = WATTS
