GA-6H/GA-6HA — GENERAL INFORMATION

WARNING

Before connecting this generators 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.

GA-6H/GA-6HA FAMILIARIZATION

Generator

The Multiquip GA-6H and GA-6HA generators have been designed as a portable dual purpose power source for 60 Hz (single phase) lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

These generators are mounted on rubber vibration isolators that have a steel base backplate which is attached to the protective steel pipe carrying frame.The protective carrying frame is made of steel tubing and fully wraps around the generators to protect against damage. See Figures 3A through 3E for the basic controls and indicators for the GA- 6H/GA-6HA generators.

These portable generators are supplied with a electrical control box. To reduce vibration caused by the engine, the control box is also placed on rubber isolators.

Control Box

The control box is provided with the following:

■120/240V twist-lock output receptacle (single phase).

■120V twist-lock receptacle (2) (single phase).

■120V GFCI single phase duplex output receptacle (GA- 6HA has two).

■21 amp main circuit breaker.

■AC Voltmeter

■Ground Terminal

■Full Power Switch

■Idle Control Switch

■Operation Switch

Excitation System

The GA-6H/GA-6HA-series generators use a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnetic passes the coil it produces approximately 19-22 AC volts.

This voltage (19-22 VAC) is then sent to the control box that contains three rectifying diodes:

zExcitation (diode 1)

zBattery (diode 2)

zSlow Down (diode 3)

The AC voltage will pass through the excitation diode that converts the voltage to DC power.

This DC power is then sent to the excitation windings housed within the main windings commonly called the "stator".

This voltage is then transferred into the rotor through induction.The rotor contains two diodes within it which rectify the DC voltage and send it out through the main windings, as AC voltage.

Alternator

The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

Engine

These generators are powered by a 11 HP, air-cooled, 4- stroke HONDA gasoline engine. Reference Table 2, for engine specifications.
