Connections
All
wiring must meet applicable local electrical codes.
Accordingly, have a qualified electrician install
and
inspect the wiring.
Mount switches and controls securely to prevent dam-
age from vibration and road shocks. All switches must

AC WIRING
*_

Wire
Types
The conductors
of
the generator set must have an
ampere rating not less than
115
percent
of
the name-
plate current rating
of
the generator. The Onan-
supplied AC feeder conductor insulation is rated at
125°C. Wires connected to the Onan feeder conductors
must meet this insulation rating,
or
must be
of
a larger
wire size (see National Electrical Code, NFPA
70).
Exhaust gas presents the hazard of
1-1
severe personal injury or death.
To
prevent exhaust gas from entering vehicle interior,
seal all openings made for conduit, wiring, etc. Seal
wiring within conduit itself.
Conduit
Install generator load conductors supplied with the
generator set in a flexible metallic conduit. Cut conduit
to
desired length, leaving extra wire as required for the
junction
box
(connecting wires must be appropriately
sized and insulated for the specified current rating).
Prepare ends of conduit to prevent sharp edges from
cutting wire insulation.
To
reposition
90”
conduit fitting, loosen locking nut
(toothed ring), turn fitting counterclockwise
to
desired
location, and retighten locking nut
Run conduit
in
such a way as not to interfere with the
movement
of
the set. This is especially pertinent to the
under-floor installation in which the set must be free to
move.
Wiring
Disconnect
Method
The feeder conductors
from
the set compartment must
terminate in a properly sized double-pole, double-throw
positive
off
switching device before the vehicle distn‘bution
panel, or connect to a generator set receptacle
box
This
assures the outside power source cannot
be
connected
simultaneously with the generator
set
Figures

and
14
illustrate
two
possible wiring connections. Figures
15
and
16
show generator set wiring diagrams and schematics.
