AC distribution panel. The shore power cord can be plugged in either at the forward or aft
connection depending on which is more convenient to the location of the dock-side power
supply.
The procedure for connecting with shore power is:
1.
Be sure the AC Power Selector switch is in the ‘OFF’ position,
2.
Be sure the dockside 50-
amp breaker switch is in the ‘OFF’ position,
3.
Plug the shore power cord into the 240-volt 50-amp dock side receptacle and into the
boat receptacle,
4.
Turn on the dockside 50-amp breaker switch,
5.
Turn the AC Power Selector switch to FWD or AFT shore power,
6.
Check the AC voltmeter and amp meter on the starboard side of the helm to be sure
that power is coming to the boat. The voltmeter will read 120 volts for both Leg-1
(A1+V1) and Leg-2 (A2+V2). The ammeter will have different readings for the two legs.
Voltmeter on left will indicate when 120 volt supply is connected with the AC circuit panel and
ammeter on right will indicate how much power is being used. The dial between the two
meters switches from leg 1 and leg 2 of the power supply.
If power is not coming to the boat check:
1.
Dockside 50-amp breaker ON?
2.
50-amp plug in the correct position?
3.
AC selector switch in correct position?
4.
Master Switch (‘1 AC SUPPLY 2’) ON?
When departing from the dock, the procedure to disconnect the shore power is:
1.
Turn the AC Selector switch to the OFF position,
2.
Turn the dockside breaker switch OFF,
3.
Unplug the shore power cord,
4.
Stow the cord in the lazarette at the stern of the boat.
The Master Switch breaker or dock breaker may be tripped if the load exceeds 50 amps. When
you first plug into shore power the battery charger will likely have a high demand so, you
should turn off other high load circuits such as the water heater and refrigerator. After an hour
or so, the battery charger will have a lower demand and the water heater and refrigerator can
be turned on.
