5.6.2 EXHAUST SYSTEM SAFETY

• Maintain a clearance of at least 3 inches (76 mm)
between exhaust system parts and any com-
bustible material (such as wood, felt, cotton,
organic fibers or other like material). If you cannot
maintain the 3-inch (76 mm) clearance, locate,
insulate or shield the exhaust part(s) so that the
temperature of any combustible material is not
raised more than 117° F (65° C) above the ambient
air temperature.
• Extend the exhaust system at least 1 inch (25 mm)
past the outer edge of the vehicle. Do not terminate
the exhaust system under the vehicle.
• Terminate the exhaust tailpipe such that exhaust
gases will not be drawn back into the generator
compartment and recirculated.
• If there is any possibility of the tailpipe or muffler
being damaged, protect these damage-prone areas
by means of a protective device (such as a skid bar).
• Install the generator exhaust system according to
safe automotive practices.
• Use enough exhaust system hangers to prevent any
part of the system from being dislocated.
• Use exhaust system parts recommended by
Generac. Using unapproved exhaust mufflers and
exhaust system parts is the responsibility of the
person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any
opening, window or vent that can be opened or is
not permanently sealed from the vehicle interior.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator engine.
• Never tee the generator engine exhaust pipe into
the vehicle engine exhaust piping. This causes
excessive back pressure on the generator engine.
Also, water from one engine can damage the other
engine.
• Plan exhaust system installation carefully. Comply
with all applicable codes, standards and regula-
tions.
QUIETPACT 50 and 70 Recreational Vehicle Generators
5.7
Be sure to read Section 5.6 on Page 28.
The following general rules apply to electrical con-
nections in a recreational vehicle:
• Qualified electricians who are familiar with applic-
able codes, standards and regulations should
install electrical wiring.
• The wiring should comply with codes, standards
and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type
approved for use in recreational vehicles and must
be mounted and installed to prevent damage from
road shock.
• Wiring must be of adequate size, have approved
insulative qualities and be properly supported.
• Conduit and wire openings into the generator com-
partment (if used) must be vapor-sealed to prevent
entry of flammable, explosive or poisonous gases
into the vehicle.

5.7.1 ELECTRICAL JUNCTION BOX

Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area you plan to install the generator (NOT on the
generator). Route the generator's AC output leads
into this junction box through approved flexible con-
duit. This is the point of first termination for genera-
tor AC output leads.

5.7.2 WIRING

• Wiring should be of stranded copper to reduce the
chance that vibration may cause breakage.
• Wire gauge size should be large enough to handle
at least 115 percent of the installed generator's
rated maximum current.
• If neutral conductors are used, they must be the
same size as other leg wires.
• Route power supply conductors from generator AC
output leads T1 (red), T3 (black) and the green
ground wire through approved flexible conduit to
the electrical junction box on the compartment
wall.
• If flexible metal conduit is used between the gener-
ator and the compartment junction box, the con-
duit end that terminates the compartment junction
box must be vapor-sealed. Flexible metal conduit
is NOT vapor tight along its entire length.
