Generac NP-50LPG Recreational Vehicle Generator
GENERATOR APPLICABILITY
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 PROPERLY INSTALLED IN
COMPLIANCE WITH (1) ANSI 119.2-1975/NFPA
501C-1974 “STANDARD FOR RECREATIONAL
VEHICLES, PART III, “INSTALLATION OF ELECTRI-
CAL SYSTEMS.” THE GENERATOR ALSO MUST
HAVE BEEN INSTALLED IN STRICT COMPLIANCE
WITH THE MANUFACTURER’S DETAILED INSTAL-
LATION INSTRUCTIONS. AFTER INSTALLATION,
DO NOTHING THAT MIGHT RENDER THE UNIT IN
NON-COMPLIANCE WITH SUCH CODES, STAN-
DARDS 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 4500 watts of (4.5kW)
of power, but cannot exceed 37.5 AC amperes of current at
120 volts or exceed 18.8 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 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, 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.
Owners/Operators must make sure to do nothing that might
render the installation unsafe or in noncompliance with applic-
able codes, standards and instructions. They should be sure
the unit has been installed to allow adequate ventilation for cool-
ing and exhaust air.
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 the unit powers
120 volt AC loads (Figure 1); or you can wire them to connect
both 120 and/or 240 volt AC electrical loads. Be sure to install
jumper wire between the circuit breakers when reconnecting
for 120/240 volts. Refer to the Installation Manual for more
information.
