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.

WATTS = VOLTAGE x AMPERAGE

The power factor of this generator is 0.8. See Table 6 below

when connecting loads.

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.

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 7

„

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.

do not exceed the maximum amps as listed.

NOTICE

Motors and motor-driven equipment draw much greater

current for starting than during operation.

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.
