AC Electric Systems
8.2
The AC System consists of the following systems or
components:
Shore Power Connection
Shore Power Breaker
Isolation Transformer
Generator (Optional)
MDP
Breakers
Components
WARNING
! !
Electricity cannot be detected without the use of
specialized test equipment. Never think you know
whether a circuit is “live”. Always have qualified,
competent professionals inspect or make repairs to
your electrical systems.
Throughout this section, the components will be sepa-
rated into categories of Power Supply and related com-
ponents such as switches, breakers, fuses, panels, char-
gers, grounding and bonding, the components that are
powered by the AC electrical system, and finally, opera-
tions 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.
The sources for power supply in your AC electric system
are the shore power, the generator, and AC electric sup-
plied through the inverter. We will explain both systems
as if your boat came to you with a generator installed. If
you opted not to have the generator, then simply omit the
sections that deal with that part of the boat. They will not
apply to your boat.
Note: It is important that you review the “Electric Shock” pam-
phlet included with your manual and understand the importance
of electrical safety. While electricity is one of our greatest
friends, it can well be your worst enemy. Be sure and follow
the warnings posted in this manual and your component or
systems manuals in your owner’s packet and practice good
safety. Always have trained, competent technicians to service
your electrical systems, it could mean your life.
8.1 Power Supply Components
As we mentioned, the two main sources for AC power
are the shore power and the generator. There is a rocker
switch on the control panel that allows you to switch

between the two power sources without energizing both
at once.
The AC power supplied in the boat is provided by a
main breaker located in the aft cabin starbaord side. The
branch breakers are in the MDP located at the nav sta-
tion.
DANGER
! !
Never work on an energized circuit! Always treat
any circuit as if it were live! Always have trained,
competent technicians to service your electrical
systems!
8.1.1 Shore Power Supply
Your boat has a shore power inlet a 30 amp 120 volt (230
overseas) line supplies power to the AC MDP.
WARNING
! !
Using a damaged or improper cord for shore power
can cause electrical shock and serious injury. Use a
cord specifically designed for shore power connec-
tion. Do not use a household extension cord.
CAUTION
! !
Water is an excellent conductor of electricity. Keep
shore power cord out of water. Do not operate any
AC device while you or the cord are in the water. To
prevent injury or equipment damage, keep all AC
system components dry.
WARNING
! !
DO NOT connect the shore power cord to the dock-
side electrical source first. You could accidentally
drop the cord into the water, which may result in
electrical shock and serious personal injury.
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
the electrical power is turned on to the unit.
