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.
