Load Application

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 0.8. SeeTable 5 below when connecting loads.

Three Phase Load

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. See Table 6.

„„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

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.
