DCA-600SSV— 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.
If wattage is not given on the equipment's
NOTE 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 5 below when connecting loads.

Three Phase Load
When calculating the power requirements for
Motors and
NOTEequipment 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. See Table 5.
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.
DANGER - ELECTRICAL SYSTEM HAZARDS
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.
If 3Ø load (kVA) is not given on the equipment nameplate,
NOTEapproximate 3Ø load output maybedeterminedbymultiplying voltage by amperage by 1.732.
