Load Application - MQ Power WHISPERWATT DCA10SPX4 Operation Manual

CONNECTING LOADS
Loads can be connected to the generator via the output
receptacles (Figure 9). Make sure to read the operation
manual before attempting to connect a load to the generator.
To protect the output receptacles from overload, a 3-pole,
45-amp, main circuit breaker is provided. ALWAYS place
ALL circuit breakers in the OFF position prior to starting
the engine.

LOAD APPLICATION

Single-Phase Load
Always be sure to check the nameplate on the generator
and equipment to ensure 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 nameplate,
approximate wattage may be determined by multiplying
the nameplate voltage by the nameplate amperage.
WATTS = VOLTAGE × AMPERAGE
The power factor of this generator is 1.0. See Table 5 below
when connecting loads.
