DCA1100SSC 60 HZ GENERATOR • OPERATION MANUAL — REV. #1 (01/17/18) — PAGE 25
LOAD APPLICATION
SINGLE PHASE LOAD
Always be sure to check the nameplate on the generator
and generator to insure the wattage, amperage, frequency,
and voltage requirements are satisfactorily supplied by the
generator for operating the generator.
Generally, the wattage listed on the nameplate of the
generator is its rated output. Generator may require
130—150% more wattage than the rating on the nameplate,
as the wattage is influenced by the efficiency, power factor
and starting system of the generator.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table 5 below
when connecting loads.
NOTICE
If wattage is not given on the generator’s name plate,
approximate wattage may be determined by multiplying
nameplate voltage by the nameplate amperage.
Table 5. Power Factor By Load
Type of Load
Power Factor
Single-Phase induction motors
0.4~75
Three-Phase induction motors
0.65~0.85
Electric heaters, incandescent lamps
1.0
Fluorescent lamps, mercury lamps
0.4~0.9
Electronic devices, communication
generator
1.0
Common power tools
0.8
NOTICE
When connecting induction motors and motor-driven
generator, pay close attention to the required starting
capacity. This starting capacity is considerable larger
than the
full running capacity
which is usually listed
on the nameplate.
The generator output cables (load) must be chosen
with these requirements in mind. When connecting
resistance loads such as incandescent lamps or electric
heaters, aload of up to the generator's rated output (kW)
can be connected.
THREE PHASE LOAD
When calculating the power requirements for 3 phase
power use the following equation:
An inadequate size connecting cable which cannot carry the
required load can cause a voltage drop which can burn out
the appliance or tool and overheat the cable. See Table 6.
When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up
to the generating set’s rated output (kW) can be used.
When connecting a fluorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.
When connecting an electric drill or other power tools,
pay close attention to the required starting current
capacity.
When connecting ordinary power tools, a capacity of up to
the generating set’s rated output (kW) multiplied by 0.8 can
be used.
NOTICE
Motors and motor driven generator draw much greater
current for starting than during operation.
NOTICE
If 3Ø load (kVA) is not given on the generator
nameplate, approximate 3Ø load may be determined
by multiplying voltage by amperage by 1.732.
DANGER
Before connecting this generator to any building’s
electrical system, a
licensed electrician must install
an
isolation (transfer) switch. Serious damage to
the building’s electrical system may occur without this
transfer switch.
