DCA-500SSK — LOAD APPLICATION
Single Phase Load
Always be sure to check the nameplate on the
generator and equipment to insure the wattage,
amperage and frequency requirements are
satisfactorily supplied by the generator for operating
the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment 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
equipment.
When connecting ordinary power tools,
a capacity of up to the generating set’s
rated output (kW) multiplied by 0.8 can
be used.

NOTE
If wattage is not given on the
equipment's name plate, approximate
wattage may be determined by
multiplying nameplate voltage by the
nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table
14. below when connecting loads.
Before connecting this generator to any building’s
electrical system, a licensed electrician must install
an isolation (transfer) switch. Serious injury or death
may result without this transfer switch.
CAUTION:
Three Phase Load
When calculating the power requirements for 3-phase
power use the following equation:
CAUTION:
Motors and motor-driven equipment
draw much greater current for
starting than during operation.
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.
z
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.
z
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.
z
When connecting an electric drill or other power
tools, pay close attention to the required starting
current capacity.
If output (kVA) is not given on the equipment
nameplate, approximate output may be
determined by multiplying voltage by
amperage by .
