PRIMEPACT 50 Recreational Vehicle Generator
1.2 GENERATOR APPLICABILITY
These generators have been designed and manufac-
tured for supplying electrical power for recreational
vehicles. You should not modify the generator or use
it for any application other than for what it was
designed. If there are any questions pertaining to its
application, write or call the factory. Do not use the
unit until you have been advised by a competent
authority.
For fire safety, the generator must have been
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, “Standard for
Recreational Vehicles, Part III – Installation of
Electrical Systems.” The generator also must
have been installed in strict compliance with
the manufacturer’s detailed installation instruc-
tions. After installation, do nothing that might
render the unit in noncompliance with such
codes, standards and instructions.
You can use this generator to supply electrical power for
operating 120/240-volt, single-phase, 60 Hertz, AC elec-
trical loads. These loads can require up to 4,800 watts
(4.8 kW) of power, but cannot exceed 40 AC amperes of
current at 120 volts, or 20 AC amperes at 240 volts for
the PRIMEPACT 50 (model 02010-0). For the
PRIMEPACT 50LP (model 04164-0), the loads can
require up to 4,500 watts (4.5 kW) of power, but can-
not exceed 37.5 amperes of current at 120 volts, or
18.8 amperes at 240 volts.
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying excessive-
ly high electrical loads may damage the genera-
tor and may shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool
and motor loads the generator will power at
one time. This total should not be greater than
the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain watts
(volts x amps = watts). Some electric motors
require more watts of power (or amps of cur-
rent) for starting than for continuous operation.
1.3 SAFETY
Before attempting to use the generator set, carefully
read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug-
gest copying and posting the “Safety Rules” in poten-
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.4 GENERATOR AC
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads by
means of a dual two-wire connection system. Note,
however, that the neutral is grounded.
The generator may have been installed so that it pow-
ers 120-volt AC loads (Figure 1.1). It can be wired to
connect both 120- and/or 240-volt AC electrical loads.
This procedure should be done by a Generac
Authorized Service Dealer or other qualified installer.
A jumper wire must be installed between the circuit
breakers when reconnecting for 120/240 volts. Refer to
the installation portion of this manual for more infor-
mation.

1.5 SPECIFICATIONS
1.5.1 FUEL REQUIREMENTS
The PRIMEPACT series generator is equipped with a
gasoline fuel system. Depending on the installation, the
generator may have either a separate fuel tank, or it
may “share” the vehicle engine’s fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle engine’s pickup tube. Such an
arrangement causes the generator engine to “run
out of gas” while adequate fuel for the vehicle
remains in the tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded REG-
ULAR grade gasoline is an acceptable substitute.
