Multiquip manual GA-2.5H - LOAD APPLICATION, Single Phase Load - 60 Hz, Power Factor By Load

Single Phase Load — 60 Hz

Always be sure to check the nameplate on the generators and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generators 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 generators is 1.0 See Table 3 below when connecting loads.

Table 3. Power Factor By Load

Type Of Load	Power Factor
Single-phase induction motors	0.4 - 0.75
Electric heaters, incandescent	1.0
lamps
Fluorescent lamps, mecury	0.4 - 0.9
lamps
Electronic devices,	1.0
communication equipment
Common power tools	0.8

When using a combination of dual

NOTE receptacles, total load should not exceed the rated capacity of the

generator.

GA-2.5H — LOAD APPLICATION

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. Always use an adequate size extension cable which can carry the required load. See Table 4.

Extension Cables

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generators and point of use (load) is held to a minimum. Use the cable selection chart (Table 4 ) as a guide for selecting proper cable size.

The idle control device is operated at a

NOTE minimum load capacity of 100W. If the load capacity is less than 100W, place the idle control switch in the OFF

position.
