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.
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, 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 shore power cable and notify a qualified electrician to check the dockside wiring.
Reverse Polarity Light Test Switch
There is a momentary switch located below the reverse polarity light in the AC breaker panel.
This switch is used to test the reverse polarity light to ensure that it is functioning. The light can
be tested by depressing the switch whenever the AC system is activated. The reverse polarity
light should be tested each time the AC system is activated. If the light does not activate when
the switch is pressed, disconnect the shore power cable and notify a qualified electrician to check
the light and the dockside wiring if necessary.
Microwave
Supplies AC current directly to the microwave oven. See the microwave manual for more
information.
Hot Water Heater
Supplies electrical current directly to the water heater circuit. The water temperature is
automatically controlled by a thermostat in the water heater control panel. Before operation, you
must have water in the water heater (see the water heater manual for more information).
Battery Charger
Supplies electrical current directly to the automatic battery charger. The battery charger charges
and maintains the 12-volt batteries simultaneously when activated. It is fully automatic and is
equipped with an amp meter to monitor charging. See the battery charger manual for more
information.
Charging also can be monitored by using the volt meters in the engine gauge cluster and the cabin
DC breaker panel. To monitor the engine batteries, activate the charger and turn the engine
battery switches on. Turn the ignition key switch for each engine to the “ON” position (DO NOT
START THE ENGINES) and read the voltage on the volt meter for each engine. To monitor
the house battery, activate the charger and turn the house battery switch on. Read the volt meter
in the cabin DC breaker panel. If the batteries are in good condition and charging properly, the
volt meters will indicate between 12 and 14.5 volts. If the reading is below 12 volts, then the
battery is not accepting a charge or the charger is not working properly. Always turn the ignition
switches off immediately after the monitoring is complete. See the battery charger manual for
more information.
