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-2.5H FAMILIARIZATION
Generator
The Multiquip GA-2.5H generator has 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 2A and
2B for the basic controls and indicators for the GA-2.5H
generator.
This portable generator is supplied with a electrical
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:
■
120V twist-lock receptacle, single phase. (S/N 5496763
and above)
control
Excitation System
The GA-2.5H generator uses 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:
z
z
z
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
This generator is powered by a 5.5 HP, air-cooled, 4-stroke
HONDA gasoline engine. Reference Table 2, for engine
specifications.

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—

the wattage is influenced by the efficiency, power factor and

Total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 KW

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.
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.

Outdoor Installation
Install the generator in a area that is free of
bystanders
generator is on secure level ground so that it cannot slide or
shift around. Also install the generator in a manner so that
the exhaust will not be discharged in the direction of nearby
homes.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
Pay close attention to ventilation when
operating the generator inside tunnels
and caves. The engine exhaust contains
noxious elements.

Indoor Installation
,
Exhaust gases from gasoline engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any gasoline engine
are very poisonous if discharged in a closed room, but
harmless if allowed to mix with the outside air. If the
generator is installed indoors, you must make provisions
for venting the engine exhaust to the outside of the building.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground. Always use the ground terminal on the generator
to ground the generator.
Article 250 (Grounding) of the National Electrical Code
(NEC) provides guide lines for proper grounding and
specifies that the cable ground shall be connected to the
grounding system of the building as close to the point of
cable entry as practical.
Mounting
The generator should always be mounted on a flat level
surface to isolate vibration of the generator when it is
running. DO NOT place the generator on slopes, the
possibility exists that the generator could slide.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 3) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the other
end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.
GA-2.5H A.C. GENERATOR — OPERATION & PARTS MANUAL — REV. #5 (03/04/08) — PAGE 19
GA-2.5H — INSTALLATION
Connecting the Ground
The nut and ground terminal on the generator should always be used to connect the generator to a suitable ground. The
ground cable should be #8 size wire minimum.
At the generator, connect the terminal of the ground cable between the lock washer and the nut (Figure 4) and tighten the
nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

Ground Power Tools
When using power tools or electrical equipment requireing AC
power from the generator, make sure connecting (power tool)
cable (Figure 5) has a ground as shown in Figure.
Figure 5. Ground Cables/Plugs
Extension Cable
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
generator 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.

Before Starting
1. Read safety instructions at the
beginning of manual.
2. Clean the generator, removing
dirt and dust, particularly the
engine cooling air inlet, carburetor
and air cleaner.
3. Check the air filter for dirt and dust. If air filter is dirty,
replace air filter with a new one as required.
4. Check carburetor for external dirt and dust. Clean with
dry compressed air.
5. Check fastening nuts and bolts for tightness.
Engine Oil Check
1. To check the engine oil level, place the generator on
secure level ground with the engine stopped.
2. Remove the filler dipstick from the engine oil filler hole
(Figure 6) and wipe clean.
Motor fuels are highly flammable and can
be dangerous if mishandled. DO NOT smoke
while refueling. DO NOT attempt to refuel
the generator if the engine is
