GLW-180H — 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.
NOTE
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
To determine the running wattage for your load, multiply the
running wattage as indicated by steps 1, 2, and 3 below:
1. INCANDESCENT LOADS
Lights, heaters and similar appliances.
Total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 KW
use a 3 KW generator.
2. SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2.
Example:
A 1 inch drill runs at 1 KW
use a 2 KW generator.
3. LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 KW
use a 24 KW generator.
CAUTION:
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.
The idle control is operated at minimum load capacity of
100W. If the load capacity is less than 100W, throw the idle
control switch to the OFF position.
