4.4 AC System
To reduce the possibility of an electrical
shock, it is important that the AC ground sys-
tem is functioning properly and that a proper
connection exists between the shore power
cord, the shore power inlet, the boat bonding
system and the outlet ground circuits. If
there is any doubt about the integrity of the
ground circuit, a qualified marine electrician
should be contacted immediately and the
AC should be disconnected until the neces-
sary repairs are completed.
The AC electrical system operates on a 120-
volt, 30 amp, 60 cycle system. Models with
CE designation; operate on a 230-volt, 16
amp, 50 cycle system.
The AC system is powered by the shore
power or by the generator. Your boat is
equipped with an isolation transformer. The
isolation transformer maintains correct AC
polarity regardless of the polarity of the
shore power supply and eliminates the need
for a galvanic isolation system. Refer to the
isolation transformer manual for additional
information.
All AC current is distributed to the AC com-
ponents through individual circuit breakers
located in the AC panel. The main breaker in
the panel protects the system from an over-
load.
4.5 AC Main Distribution
The AC panel is located in the cabin. The
following are descriptions of the AC panel
equipment and the breakers that protect the
accessories:
AC Multi-Meter
Use the arrow keys to scroll through digital
readouts for amperage (A), voltage
(V),cycles (hertz) (Hz) and watts (W).
• (A) Indicates the total amperage being
drawn through the AC MDP. It is the total
current level of all of the AC equipment
in operation at the time.
• (V) Indicates the voltage supplied to the
panel. Ideally the voltage should be
approximately 240 volts (230 for CE) but
never less than 208 volts.
• (Hz) Indicates cycles which should be 60
(50 for CE).
• (W) Indicates total watts being con-
sumed as a result voltage x amperage.
AC Main
Protects the general distribution network.
This breaker should be on when the boat is
using shore power for its source. This
breaker is very sensitive. The resulting
power surge that occurs when connecting
the dockside cord may cause the main
breaker to trip. To avoid this surge, turn the
main breaker to "OFF" position before plug-
ging or unplugging the shore power cord.

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.
