Shore Power Connections; 120 Volt Ac Equipment - Four winns 278 VISTA Owner's Manual

A. Shore Power Connections
To prevent electric shock hazards, use only
equipment with approved three wire electrical
plug connections. Be sure each item being
used has been tested and is free of electrical
shorts and ground faults.
Fifty foot, ten gauge, three-wire, shore power cords
are provided with dockside wiring. The shore power
cords on 60 Hertz systems have 30 amp twistlock-
type connectors. They have a power "ON" indicator
light to ease in connecting and troubleshooting. This
connector complies with the American Boat and Yacht
Council (ABYC) standards.
Some marinas are not equipped with approved
twistlock-type receptacles. An adaptor is available
from Four Winns which converts the twist-lock shore
plug to a three-wire grounded household type plug.
Use only an approved adaptor when an adaptor is
necessary.
DO NOT use a two-wire adaptor to connect to
a three-wire system. These adaptors do not
provide adequate grounding.
Shore power connection procedure is as follows:
1. Turn off the boat's SHORE POWER (main)
breaker switch before connecting or disconnecting
the shore power cable.
2. Connect shore power cable to the dockside inlet
receptacle of the boat first, then connect it to
dockside shore power outlet.
NOTICE
Always connect the cord to the power inlet
receptacle of the boat before making connec-
tions to the shore power source.
3. Check for reversed polarity on the AC panel.
If the reversed polarity light is activated, immedi-
ately disconnect the shore power cord. See
Section H-8C - Reverse Polarity Indicator.
Electrical Systems - Section H
4. To disconnect shore power, turn off the main
breaker switch on the AC electrical panel and
disconnect the power cord from the shore power
dockside receptacle first. Then, disconnect the
cord from the boat.
NOTICE
Always disconnect the shore power cord from
the dockside first before disconnecting from
the boat.
NOTICE
Always remember to disconnect the shore
power cord from the dockside first before
leaving the dock. Properly store shore power
cord.
B. 120 Volt AC Equipment
All 12 volt equipment is isolated from the 120 volt AC
system (except the refrigerator which is dual voltage).
Appropriately labeled circuit breakers protect all AC
systems on the boat. The receptacles can be used for
120 volt (220 volts on 50 Hertz models) household
appliances. Refer to the following list for information
on appliances and other equipment.
Battery Charger - The battery charger is controlled
by a circuit breaker on the AC electrical panel in the
cabin labeled CHARGER. In order for the charger to
charge the battery(s) the circuit breaker must be "ON"
while connected to dockside power. If a generator is
available and operating it too will allow the batteries to
be charged by the battery charger.
Refrigerator - The REFRIGERATOR circuit breaker
must be on to operate on 120 voltage. If this breaker
is off, the galley refrigerator will automatically operate
on the 12 volt system. This can deplete the battery.
Excessive drain on the battery may cause irreparable
battery damage. The refrigerator will automatically
operate on 120 volts when provided. Refer to Section
L-1C - Galley Equipment in this manual for more
information.
