supply valve, supply hose, and a fuel filter, along with the
return hose, and electric fuel pump.
The exhaust system is made up of an exhaust hose, a
muffler, and the exhaust outlet. See your Mechanical
Arrangement Illustrations for locations of these compo-
nents. They can be found at the end of each pertinent
section, or at the end of this section. The entire AC sys-
tem will be laid out in an illustration showing locations for
each of the components.
The fuel supply components will be described in greater
detail in the Fuel Section and the exhaust will be described
in the Waste and Sanitary Section of this manual.
8.1.6 Breakers, Switches, and Fuses
All electrical systems aboard your boat are provided with
over-current protection in the form of breakers or fuses.
Examples of breakers are the system or component con-
trols at the Main Distribution Panel, or MDP Systems that
would normally require you to energize them for use and
are provided with switches.
The breaker and switch panels are detailed further in the
end of this section under “Legends.”
8.1.7 Outlets and GFI Components
The outlets aboard your boat are for AC electrical con-
nections to supply power to your AC accessories. They
are just like your outlets in your home and supply 120 volt
(230 volt overseas) AC power.
There are 2 required GFI outlets aboard your boat. One
is in the galley, one at the Nav station. Though there are
several other outlets, they are wired in the circuit of an
existing GFI. The other outlet such as the one that sup-
plies power to your microwave receives power from the
MDP and breaker protected at that point. These are usu-
ally placed behind cabinets or the components that they
supply power to and aren’t visible.
Though the outlets are a system or a component such
as in the next subject, we have placed the descriptions
in the Power Supply subject due to the purpose of their
installation.
As with the DC System, there are several AC powered
systems or components aboard your boat. Here we will
break those down for you with a function and description
of each one. Later in the Operations and Maintenance
section, we will describe the use or operation of these
systems or components.
8.2 Systems and Components.
8.2.1 Battery Charger
The battery charger (Fig. 8.3) can be located by reviewing
your power supply components illustration in the begin-
ning of the DC Electric section. The charger is protected
by a reset on the battery switch panel.
The circuit breakers for the battery chargers are located
on the Main Distribution Panel (MDP).
8.2.2 Water Heater
CAUTION
! !
Be certain the water heater is full of water and does
not contain air. If the water heater is not full of wa-
ter, damage to the heating elements may result when
electrical power is turned on to the unit.
The water heater use and function is described in the
Water Systems Section. Here we will detail the electrical
side of the heater.
The water heater is powered by the AC MDP. It is much
the same as an electric water heater in your home except
in this case, the heater uses 120 volt (230 overseas), but
it uses elements to heat the water to a specified tempera-
ture. Consult the manufacturer’s documentation for any
internal information about the water heater.
8.2.3 Microwave
The microwave is powered with the 120 volt (230 over-
seas) power through the breaker marked “Microwave.”
There is a 120 volt (230 overseas) receptacle behind the
microwave that it is plugged into. This outlet is not part
of the GFI circuit. It is protected by the breaker on the
MDP.
