4.4 AC System
The AC electrical system operates on a 240
volt, 50 amp, 60 cycle system. Models with
CE designations operate on a 230 volt, 32
amp, 50 cycle system.
The AC system is fed by the shore power or
by the generator. Your boat is equipped with
an isolation transformer. The isolation trans-
former maintains correct AC polarity regard-
less of the polarity of the shore power supply
and eliminates the need for a galvanic isola-
tion system and a reverse polarity indicator.
Refer to the isolation transformer manual for
additional information.
The main breakers in the AC Main Distribu-
tion Panel (AC MDP) are equipped with a
selector slide to prevent the shore power
source and the generator source from being
energized simultaneously and damaging the
electrical system components. These
breakers protect the system and compo-
nents from an overload. All AC current is
distributed to the AC components through
individual 120V/240V (230V for CE) circuit
breakers located in the AC MDP.
4.5 AC Main Distribution
The AC MDP is located in the aft cabin. The
following are descriptions of the AC MDP
and the breakers that protect the accesso-
ries:
! DANGER
ELECTROCUTION, FIRE OR
EXPLOSION HAZARD
Contact with live wires or working on
an energized electrical system can
cause electrocution. It can also cause
sparks, resulting in fire and/or explo-
sion. Both cases will result in death or
serious injury. DO NOT work on an
energized system or allow unqualified
personnel to work on the system.
