Generac NP-50G Recreational Vehicle Generator
GENERATOR APPUCABILITY
These generators have been designed and manufactured 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 pertain­
ing to its application, write or call the factory. Do not use the
unit until you have been advised by a competent authority.
DANGER: For fire safety, the generator must have
been property installed in compliance with (1)
ANSI 119.2-1975/NFPA 501C-1974 “Standard for
Recreational Vehicles, Part III, “Installation of Elec­
trical Systems.” The generator also must have
been installed in strict compliance with the manu­
facturer’s detailed installation instructions. After
installation, do nothing that might render the unit
in non-compliance with such codes, standards and
instructions.
You can use this generator to supply electrical power for oper­
ating 120/240 volts, single phase, 60 Hertz, AC electrical
loads. These loads can require up to 4800 watts of (4.8kW)
of power, but cannot exceed 40 AC amperes of current at 120
volts or exceed 20 AC amperes at 240 volts.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying exces­
sively high electrical loads ntay 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, multi­
ply 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.
INSTALLATION
This Owner's Manual has been prepared under the assump­
tion that a competent, qualified technician installed the
generator. We also assume the installer complied with all
applicable codes, standards and regulations pertaining to
installation.
An INSTALLATION MANUAL was shipped with the genera­
tor. That manual contains manufacturer’s instructions and
recommendations for installing the unit into a recreational
vehicle. After installation, installers should forward the Instal­
lation Manual to Owners/Operators for their information.
Owners/Operators have the responsibility to make sure that
nothing is done that might render the Installation unsafe or in
non-compliance with applicable codes, standards and instruc­
tions.
SAFETY
Before attempting to use the generator set, carefully read
GENERAL SAFETY RULES inside the cover of this Manual.
Comply strictly with these RULES to prevent accidents and
damage to equipment and/or property. We suggest that copy­
ing and posting GENERAL SAFETY RULES in potential hazard
areas of the vehicle. Stress safety to all operators and poten­
tial operators of this equipment.
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 2-wire con­
nection system. Note, however, that neutral is grounded.
The generator may have been installed so that units power
120 volts AC loads (Figure 1); or you can wire them to con­
nect both 120 and/or 240 volts AC electrical loads. Be sure
to install jumper wire between the circuit breakers when recon­
necting for 120/240 volts. Refer to the Installation Manual for
more information.
