SGW-250SS DC WELDER/AC GENERATOR — PARTS & OPERATION MANUAL — REV. #2 (08/08/01) — PAGE 27
SGW-250SS — 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.
The power factor of this generator is 1.0. See Table 5. below
when connecting loads.
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.
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.
The idle control is operated at minimum load capacity of
100W. If the load capacity is less than 100W, place the idle
control switch to the OFF position.
CAUTION:
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.
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
