4.5 AC Main Distribution
AC Breaker Panel
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 Ammeter
Indicates the total amperage or current
being drawn through the AC panel.
AC Volt Meter
Indicates the voltage supplied to the panel.
Galvanic Isolator Monitor
The purpose of the galvanic Isolator is to
allow the boat’s bonding system to be iso-
lated electrically from the dock and other
vessels at low voltages but to maintain the
connection to the shore ground at high volt-
age.
This low voltage isolation will prevent the
boat and engine zincs from protecting the
underwater fittings on another boat sharing
the common marina AC ground wire, so that
your anodes are protecting your boat only.
The Galvanic Isolator is of the “fail safe”
design meaning that if a failure of the device
were to occur, it will fail in a safe condition
that maintains the electrical path through the
green ground wire. In the “fail safe” mode
galvanic isolation will be lost to the boat’s
underwater metal fittings. Refer to the gal-
vanic isolator monitor owner's manual.
Reverse Polarity Light
The red light indicates reverse polarity cur-
rent supplied to the panel. This situation will
cause the red light to illuminate. Additionally,
a relay attached to the main breaker will
automatically turn the main breaker off
whenever reverse polarity occurs. If reverse
polarity occurs, immediately turn off all cabin
AC breakers and dockside outlet breakers.
Disconnect the power cable from the dock-
side outlet and notify a qualified electrician
to check the dock side wiring.
AC Main Breaker
Protects the general distribution network.
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, always turn the
main breaker to the “OFF” position before
plugging or unplugging the shore power
cord.
Microwave
Supplies AC current directly to the micro-
wave oven. See the microwave manual for
more information.
Air Conditioner (Optional)
This breaker supplies electrical current to
the air conditioning control panel and the air
conditioner raw water pump on this optional
!
DANGER
To reduce the possibility of an electri-
cal shock, it is important that the ac
ground system 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 integ-
rity of the ground circuit, contact a
qualified marine electrician immedi-
ately. Disconnect the AC until the nec-
essary repairs are completed.
