Single Phase Load — 60 Hz

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.

GDP-5000H — LOAD APPLICATION

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.

CAUTION:

Before connecting this generator to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch. Serious injury or death may result without this transfer switch.

Three Phase Load — 180 Hz

180 cycle, three phase, 230V, motor-in-head vibrators can be operated with this generator. When operating more than one concrete vibrator, the ON/OFF switch of each concrete vibrators shall be turned on one at a time.

If they are switched on simultaneously, the circuit breaker may trip or the engine may be overloaded.

NOTE

If output (kVA) is not given on the vibrators nameplate, approximate output may be determined by multiplying voltage by amperage by .
