6.3 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.
Note: Isolated ground kits are available as options for
steel- or aluminum-hulled vessels. Consult your
local dealer/distributor for more information.
The scope of these topics is too extensive to be fully
discussed here. Consult your local marine authority for
more information.
Before installing the generator set, check the available
wiring diagrams in the operation manual to become
familiar with the electrical system.
