OS 285

DO NOT OPERATE THE AC ELECTRICAL SYSTEM FROM SHORE POWER WITH RE-

VERSE POLARITY. REVERSE POLARITY WILL DAMAGE THE SYSTEM AND EXPOSE

PASSENGERS TO ELECTROCUTION HAZARDS. THIS CONDITION COULD ALSO CAUSE

A FIRE IN THE ELECTRICAL SYSTEM.

DISCONNECTING PROCEDURE FOR SHORE POWER CONNECTION

Turn the main breaker on the AC panel and the disconnect switch on the dockside outlet to the “OFF” positions.

Disconnect the cable from the dockside outlet and replace the outlet caps. Disconnect the cable from the boat

and close the inlet cap. Store cable.

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 Amp Meter

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 monitor for the galvanic isolator is mounted in the AC breaker panel. The monitor continuously tests

and displays the condition of polarity, ground wire continuity and galvanic isolator functioning. Refer to the

galvanic isolator monitor owner's manual.

Reverse Polarity Light

The red light indicates reverse polarity current supplied to the panel. This situation will cause the red light

to remain lit. Additionally, a special relay attached to the main breaker will automatically turn the main

breaker off whenever reverse polarity is achieved. If reverse polarity is achieved, immediately turn off all

cabin AC breakers and dockside outlet breakers. Disconnect the power cable from the dockside outlet and

notify a qualified electrician to check the dockside 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 surge, always turn the

main breaker to the “OFF” position before plugging or unplugging the shore power cord. The AC

panel also is equipped with a relay that will cause the main breaker to trip when reverse polarity current is

detected.

Microwave

Supplies AC current directly to the microwave oven. See the microwave manual for more information.

Air Conditioner (Optional)

Supplies electrical current to the air conditioning control panel and the air conditioner raw water pump when

this option is installed. Otherwise it is reserved for additional AC equipment. This breaker will trip if sea

water is not being supplied to the air conditioning unit. If this breaker trips, reset and check for water flow

out of the air conditioning thru-hull. Refer to the air conditioner owner’s manual for additional information.
