The two main elements that decide where a generator
should be located are
1
the availability of space, and
2
the adequacy of structural support. Thought should be
given to ventilation, cooling and exhaust systems as well,
and these areas will be covered later.
The generator is usually located in the engine room,
where there is already plenty of ventilation. The main
engine stringers can be used as supports. If the
generator set cannot be located in the same compartment
as the propulsion engine, it should be in a properly
ventilated compartment isolated from the living quarters.
Generator set location should provide easy access for
regular maintenance and fuel system adjustment. Bear
in mind that the generator set will require replacement
of worn parts and eventual overhaul. The control panel
should be located so it can be easily monitored during
generator operation. For ease of servicing, make sure that
the sea cock and the inlet water strainer are completely
accessible.
Northern Lights generators are supported on a frame
that incorporates a drip pan and is equipped with
vibration isolation mounts. A rigid mounting base must
be used to mount the set to the engine stringers, or other
strong supports. This rigid base anchors the set and
prevents noise transmission through the boat frame. The
mounting base can be either metal or wood. A thicker and
more rigid base will cut down on the drum-like tendency
of the drip pan to magnify engine noise.
It is important to use marine grade plywood or
lumber; make sure that the generator base supports the
complete underside of the drip pan. Be sure that the base
does not touch any of the bulkheads or free board, which
will amplify noise transmission from the engine. Mount the
generator away from bilge splash and low-lying vapors.
Because
fl exible mounts are used, the generator will
rock during engine operation in rough seas. Therefore,
you must plan for adequate clearance on all sides. Use
fl exible connections on all lines and connections.
Dimensions, weights, and maximum operating
angularity vary by model and are available from
Northern Lights.
