Because of the different recreational vehicle models
and the variations between the models, it would be
extremely
difficult,
if
not
impractical,
to

detailed instructions on every installation possibility.
For that reason, instructions and illustrations
in
this
manual are general in nature. Illustrations are not
intended to serve as
detailed installation blueprints.
The installation should comply strictly with all applica-
ble
codes, standards and regulations pertaining to the
installation and use of this product.
If
any portion of
this
manual appears to be
in
conflict with such codes,
standards or
regulations, the applicable codes, stan-
dards or regulations must take precedence over the
manual.

EQUIPMENT
DESCRIPTION
Instructions and information
in
this section pertain to
Generac
air-cooled generators - more specifically,
the installation of NP30 recreational vehicle genera-
tors. These generators are designed specifically for
installing
in
recreational vehicles.
ENGINE
GENERATOR
OPERATING
SPEED
The generators are driven by single-cylinder engines.
The engines drive revolving fields (rotors), high fre-
quency, permanent magnet alternators. The genera-
tors supply 120 volts AC at 60 Hertz. The generators
revolving
fields
are
driven
at
a
variable
speed
depending on the instantaneous demand for power.
Computers
monitor
that
demand
and
adjust
the
engine speed to provide adequate power to the con-
nected loads.
GENERATOR
AC
CONNECTION
SYSTEM
The generators are equipped with single voltage AC
connection systems.
The
following facts pertain to
such a connection system:
•
On
the
units,
the
120
volts,
connections
system
is
pro-
tected
by
a circuit
breaker.
•
The
AC
connection
system
on
all
air-cooled generators
use
a
GROUNDED
neutral.
• A
separate
green
ground
wire
is
connected
to
the
recre-
