Installation In Steel Or Aluminum
Vessels
Installation of a generator set in a vessel constructed of
a material capable of conducting current (e.g.: steel or
aluminum) is subject to considerations not normally
encountered in fiberglass or wood vessels. These
differences include equipment grounding, grounding of
neutral conductors, ground-fault protection, and
isolation of galvanic currents.
While the scope of these topics is too extensive to be
fully discussed here, this manual makes references to
the appropriate governing bodies for further
investigation.
The information provided here is a guideline to boat
manufacturers and generator set installers. This
information is not intended or implied to be limited to
these sources and is subject to revision by the
appropriate governing bodies.
Before installing the generator set, check the available
wiring diagrams in Section 5 to become familiar with the
electrical system.
