Section 1 – General Information
PRIMEPACT 66G and 66LP Recreational Vehicle Generators
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 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 your generator set to supply electrical
power for operating one of the following electrical
loads:
• PRIMEPACT 66G: 120 and/or 240 volts, single
phase, 60 Hz electrical loads. These loads can
require up to 6600 watts (6.6 kW) of power, but
cannot exceed 55 AC amperes of current at 120
volts or exceed 27.5 AC amperes at 240 volts.
• PRIMEPACT 66LP: 120 and/or 240 volts, single
phase, 60 Hz electrical loads. These loads can
require up to 6200 watts (6.2 kW) of power, but
cannot exceed 51.7 AC amperes of current at 120
volts or exceed 25.8 AC amperes at 240 volts.
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying exces-
sively high electrical loads may damage the
generator 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 current) for starting than for continuous
operation.
1.3 INSTALLATION
This Owner’s Manual has been prepared under the
assumption that a competent, qualified technician
installed the generator into an industrial vehicle. We
also assume the installer complied with all applicable
codes, standards and regulations pertaining to instal-
lation.
An INSTALLATION MANUAL was shipped with the
generator. That Manual contains manufacturer’s
instructions and recommendations for installing the
unit into an industrial vehicle. After installation,
installers should forward the Installation Manual to
Owners/Operators for their information.
Owners/Operators have the responsibility to make
sure that nothing is done that might render the instal-
lation unsafe or in non-compliance with applicable
codes, standards and instructions.
1.4 SAFETY
Before using the generator set, carefully read GEN-
ERAL SAFETY RULES inside the cover. Comply with
these RULES to prevent accidents and damage to
equipment and/or property. Generac suggests copy-
ing and posting the GENERAL SAFETY RULES to
potential operators of this equipment.
1.5 GENERATOR AC CONNECTION
SYSTEM
These air-cooled generator sets are equipped with
dual stator AC power windings. These two stator
windings supply electrical power to customer electri-
cal loads by means of a dual 2-wire connection sys-
tem.
Generators may be installed to provide the following
outputs:
1) 120 VAC loads only — one load with a maximum
total wattage requirement equal to the generator’s
rated power output (in watts), and 120V across the
generator output terminals. Figure 1.1, page 6,
shows the generator lead wire connections for
120VAC ONLY.
2) 120/240 VAC loads — one load with a maximum
total wattage requirement equal to the generator’s
rated power output, and 240V across the generator
output terminals; or two seperate loads, each with a
maximum total wattage requirement equal to half of
the generator’s rated power output (in watts), and
120V across the generator output terminals.
Figure 1.2, page 6, shows the generator lead wire
connections for 120/240 VAC loads.
