DC Electric Systems
This section will provide you with the information necessary
to understand and operate your DC Electrical Systems.
It is not the scope of this manual to educate you on repair,
or extending the electrical system. We cannot educate
you in the principals of basic electricity. The scope of your
manual is to provide you with the basic information you
will need for safety, operation, and maintenance of these
systems.
There are two main categories, the DC Electrical system
and the AC Electrical systems. These are two entirely
different systems though in lots of areas one dependant
on the other.
From that point we will subdivide the main categories
into sections beginning with the source of the power
and continuing throughout the system to the component
based in the systems circuitry. Remember within each
main system are many sub-systems or circuits. These
will be outlined as best as we can from beginning to end.
WARNING
! !
Do not rely on the information in this manual as a re-
pair guide, as always only competent electrical ser-
vice personnel should attempt to repair any electri-
cal equipment or extension of the electrical systems.
To do so would risk electrical shock, or damage to
the boats systems or components.
7.1 The DC Electrical System
The DC System consists of the following systems or
components:
Batteries
Battery Switches

Distribution Panel
Oil Changer (Option)
Shower Sump
Windlass
Generator Starter

Throughout this section, the components will be separated
into categories of Power Supply and related components
such as switches, breakers, fuses, panels, chargers,
grounding, the components that are powered by the DC
electrical system, and finally operations and suggestions
for control or usage of the systems or components. At the
end of the section, you will find a “Legends” section that
will detail the switch, breaker, and control panels aboard
your boat.
