Electrical System
The AC system can be fed by either the shore
power inlet or by the generator. Main breakers in
the AC panel are used to select the source of power
desired, the port side shore inlet, the starboard
side shore inlet or Generator Main. The AC main
breakers must be switched to the OFF position
before selecting a different power source.
All AC current is distributed to the AC accessories
through individual circuit breakers located in the
cabin AC panel. The main breakers protect the
system from an overload. All AC outlets in the
cabin and cockpit are protected by ground fault
interrupters to protect against electrical shock.
While moored dockside, 120 volt AC power should
be utilized from dockside power, if available. A
cord set is provided to supply power from the
shore power outlet to the boat’s 120 volt AC
system.
TO REDUCE THE RISK OF ELECTRICAL SHOCK IN WET
WEATHER, AVOID MAKING CONTACT WITH THE SHORE CABLE
OR MAKING A CONNECTION TO A LIVE SHORE OUTLET. NEVER
SPRAY WATER ON ELECTRICAL CABLES WHILE WASHING
DOWN DECKS.
TO REDUCE THE POSSIBILITY OF AN ELECTRICAL 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
INTEGRITY OF THE GROUND CIRCUIT, A QUALIFIED MARINE
ELECTRICIAN SHOULD BE CONTACTED IMMEDIATELY AND
THE AC POWER SHOULD BE DISCONNECTED UNTIL THE
NECESSARY REPAIRS ARE COMPLETED.
Recommended procedure for making a
shore connection:
Turn the AC Shore Main breakers to the “OFF” posi-
tion. If the dockside outlet includes a disconnect
circuit breaker, turn it to the “OFF” position as well.
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 chang between the
boat and the dock. Make sure the cable doesn’t
come in contact with the water and connect the
cable in the boat plug inlet and then 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 circuit breaker to
the ON position. Then turn the circuit breaker at
the boat inlet connection on and check for proper
polarity. If reversed polarity has been achieved,
the red “FAULT” light on the ELCI panel will light
and the main inlet breaker will automatically trip.
If this should happen, make sure the inlet main
breaker and Shore main breaker on the cabin AC
panel are in the “OFF” position, then turn the dock
power breaker off. If the green “POWER” light il-
luminates and the main inlet breaker does not trip
when power is supplied to the panel, the polarity
is correct and the Port or Starboard Shore main
breaker on the cabin AC panel can be moved to
the “ON” position.
After activating the system, check the ELCI panel
at the inlet connection plug for faults. The green
“POWER” LED should show steady illumination 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 “FAULT” 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 illumination and the ElCI does
not trip again, the circuit is correct and activated.
If the ELCI continues to trip and the red “FAULT”
LED is lit after being reset, there is a problem
with the AC electrical system and it is unsafe to
use. Make sure the inlet connection panel main
breaker and the Shore main breaker on the cabin
panel are in the “OFF” position and turn the dock
power breaker off. Disconnect the shore power
supply cord from the boat and notify a qualied
marine electrician to check the wiring and correct
the problem.
REVERSED POLARITY AND GROUND FAULT CONDITIONS
WILL DAMAGE THE SYSTEM AND EXPOSE PASSENGERS
TO ELECTROCUTION HAZARDS THAT WILL CAUSE SEVERE
INJURY OR DEATH. THIS CONDITION COULD ALSO CAUSE
A FIRE IN THE ELECTRICAL SYSTEM. NEVER OPERATE THE
AC ELECTRICAL SYSTEM WITH REVERSED POLARITY OR A
GROUND FAULT CONDITION.
