Electrical System
Cabin AC Panel Circuit Breakers & Reverse Polarity Light
Recommended procedure for making a
shore connection:
Turn the AC main breakers to the OFF position.
If the dockside outlet includes a circuit breaker,
turn it to the OFF position also.
To avoid strain on the cable make sure it has more
slack than the mooring lines. Dress the cable so it
cannot be damaged by chafing between the boat
and the dock. Make sure the cable doesn’t come
in contact with the water and connect the cable
to the boat plug inlet and then to the dockside
outlet, making sure the connection plugs include
a three-prong plug with a ground wire. Tighten
the lock rings on both the shore and the boat
connector plugs.
Turn the dockside disconnect switch or circuit
breaker to the ON position. Then turn the circuit
breaker at the boat inlet connection ON and check
for proper polarity. If reverse polarity has been
achieved, the red reversed polarity indicator in
the shore power inlet panel and cabin 120 volt AC
panel will light. If this should happen, make sure
the main breakers on the AC panel are in the OFF
position and turn the inlet and dockside power
circuit breakers OFF. Special relays attached to
the main breakers in the cabin AC panel will au-
tomatically turn the main breakers off whenever
reverse polarity is achieved. Notify a qualified
electrician to check the wiring at the dock outlet.
If the red reversed polarity lights do not illuminate
and the green, power available light in the shore
power inlet panel is lit when power is supplied,
the polarity is correct and the AC main switches
can be moved to the ON position.
Check the ELCI lights in the inlet panel for faults.
The green “POWER” LED should show steady illu -
mination and the red “FAULT” LED should remain
off. The ELCI trips and opens the main circuit
when there is a ground fault condition. If the
red LED is continuously illuminated, the ELCI has
tripped due to a ground fault condition. Some
faults are self-clearing. Try resetting the ELCI
once. If the green LED shows steady illumina-
tion and the ElCI does not trip again, the circuit
is correct and activated.
If the reversed polarity light is lit or the ELCI con-
tinues to trip and the red “FAULT” LED is lit after
being reset there is a problem with the AC electri-
cal system and it is unsafe to use. Make sure the
main breakers on the cabin AC panel and shore
power inlet panel are in the OFF position and turn
the dockside circuit breaker OFF. Disconnect the
shore power supply cord from the boat and notify
a qualified marine electrician to check the wiring
and correct the problem.
DANGER
REVERSED POLARITY WILL DAMAGE THE SYSTEM AND
EXPOSE PASSENGERS TO ELECTROCUTION HAZARDS. THIS
CONDITION COULD ALSO CAUSE A FIRE IN THE ELECTRICAL
SYSTEM. DO NOT OPERATE THE AC ELECTRICAL SYSTEM
FROM SHORE POWER WITH REVERSED POLARITY.
WARNING
ELECTRIC SHOCK CAN CAUSE SEVERE INJURY OR EVEN
DEATH. DO NOT ATTEMPT TO CORRECT THE WIRING
YOURSELF. ALWAYS HAVE A QUALIFIED ELECTRICIAN CHECK
WIRING.
KEEP CHILDREN AWAY FROM ANY ELECTRICAL CABLES OR
EQUIPMENT AND ALWAYS USE GROUNDED APPLIANCES ON
BOARD YOUR BOAT.
