A. Shore Power Connections
To prevent electric shock hazards, use only equ-
ipment 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 connec-
tors. This connector is approved by National Marine Manu-
facturers Association and the American Boat and Yacht
Council.
Some marinas are not equipped with approved twistlock-
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 ap-
proved adaptor when an adaptor is necessary.
DO NOT use a two-wire adaptor to connect to a
three-wire system. These adapters do not pro-
vide 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. If the reversed polarity
light is activated, immediately disconnect the shore
power cord. See Section H-6C - 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 recep-
tacle 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 sys-
tem (except the refrigerator which is dual voltage). Appro-
priately 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 la-
beled BATTERY CHARGER
Refrigerator - The 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 sys-
tem. 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.
Water Heater - The WATER HEATER circuit breaker sup-
plies power to the water heater. Refer to Section J-2C
Water Heating Systems in this manual for more informa-
tion.
NOTICE
DO NOT supply electrical power to an empty
water heater. Activate the FRESH WATER cir-
cuit breaker and switch to start the water pump
and prime the system. Be sure there is adequate
water in the system before turning on the water
heater. Failure to comply will result in immedi-
ate damage to the heater element.
Electric Stove - The RANGE circuit breaker must be acti-
vated to supply power to the electric stove on all Vista®
models. Refer to Section L-1A - Galley Equipment in this
manual for more information.
Microwave - The MICROWAVE breaker must be activated
to supply power to the microwave on all Vista® models.
