Load Application/Generator Output - MULTIQUIP MQ POWER SG1400C3 Operation Manual

Single pHaSe load
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage, frequency,
and voltage 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.
.
NOTICE
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 1.0. See Table 7 below

When calculating the power requirements for 3-phase
power use the following equation.
NOTICE
If 3Ø load (kVA) is not given on the equipment
nameplate, approximate 3Ø load may be determined
by multiplying voltage by amperage by 1.732.
NOTICE
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. Refer to
Table 8 to select the correct cable size.
„ When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up to
the generator's rated output (kW) can be used.
„ When connecting a fluorescent or mercury lamp, a
capacity of up to the generator'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 generator's rated output (kW) multiplied by 0.8 can be
used.

electrical system, a licensed electrician must install
125 ft.
a transfer switch. Serious damage to the building's
100 ft.
electrical system may occur without this transfer switch.
