power is securely connected, turn the MAIN breaker(s)
back on. If the connection is broken and later re-se-
cured, the circuit breaker may trip. Connections must
be secure for uninterrupted dockside service.
H - 11 DOCKSIDE OPERATION
If any abnormalities appear during dockside
operation, DISCONNECT the system immedi-
ately to prevent electric shock hazards! Have
the boat's electrical system and the shoreside
receptacles checked as soon as possible.
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 connec-
tor complies with the American Boat and Yacht Council
(ABYC) standards.
Some marinas are not equipped with approved twist-
lock-type receptacles. An adaptor is available from
Four Winns which converts the twistlock 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 adapters do not
provide adequate grounding.
Shore power connection procedure is as follows:
1. Turn off the boat's main breaker switch before con-
necting or disconnecting the shore power cable.
2. Connect shore power cable at the boat first, then
connect it to dockside shore power outlet.

NOTICE
Always connect the cord to the power inlet recep-
tacle of the boat before making connections to
the shore power source.
3. Check for reversed polarity on the AC panel. If the
reversed polarity light is activated, immediately
disconnect the shore power cord. See Section
H-11C - Reverse Polarity Indicator.
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 re-
ceptacle first. Then, disconnect the cord from the
boat.
NOTICE
Always disconnect the shore power cord from
the dockside first before disconnecting from the
boat.
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 BATTERY CHARGER or CHARGER/REFRIG-
ERATOR depending on the Vista™ model. 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 or CHARGER
REFRIGERATOR circuit breaker must be on to operate
on 120 voltage. If this breaker is off, the 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.
