Generator set location is preferable in the same room or
compartment as the propulsion engine, as this is usually
a
well
ventilated area, insulated, close to the fuel supply
and isthe center of electrical load distribution. However,
a generator set cannot be installed in the propulsion
engine compartment unless specific conditions are met.
USCG
regulation
33CFR183
pertains to gasoline fuel
systems, and requires a generator set operating in a
gasoline fuel environment to be “ignition protected.”
This means a set capable of operating in an explosive
environment without igniting that environment. Properly
installed and operated, the
MCE
generator set can
operate in an explosive environment.
Gasoline fire or explosion can result
in severe personal iniury or death.
Do
not installa gasoline generator set in the same room or
compartment
of
a
diesel propulsion engine or generator
set. The diesel unit may not be ignifion protected and
may ignite gasoline fumes. Be sure
a
gasoline generator
set
is
insfalled in its own room or compartment.

The floor must be flat and givesupport directly underthe
genset mounting points (Figures
3-1
and
3-2).
A
one
inch
(25
mm)
clearance around the unit is required to
permit rocking on its mounts without restraint; and
4.2
inches
(106
mm) for servicing the oil filter. Additional
space must be allowed for proper ventilation for cooling
and combustion, as well as service access.
Also
allow
access for periodic maintenancesuch as oil fill, coolant
fill,
spark plug replacement, etc. The entire exhaust
system must be accessible
so
a periodic visual and
audible check for leakage can be made by the operator.
Install
two
hold-down clamps ortwo through boltsto the
drip pan on both sides of the generator set. Tighten the
clamps securely to the mounting base with bolts and
flatwas hers.
Select a location that will allow adequate space on all
sides for ventilation and servicing the set, preferably on
and parallel with the keel or vessel center line. Keep the
generator set away from living quarters, and away from
bilge splash and vapors.
