Air Conditioner - The AIR CONDITIONER circuit breaker
supplies power to the air conditioner. Dual Dockside is
installed on Four Winns 278 models with this option. Refer
to Section I-3 Air Conditioning in this manual for more
information.
Alcohol/Electric Stove - The RANGE circuit breaker must
be activated to supply power to the alcohol/electric stove
on the 278 model. Refer to Section I-1 Galley Equipment
in this manual for more information.
Battery Charger - The battery charger is controlled by a
circuit breaker on the AC electrical panel in the cabin
labeled BATTERY CHARGER or CHARGER/OUTLET.
With dockside power connected and the BATTERY
CHARGER circuit breaker on, the charger will convert
120 volt AC power to 12 volt DC power.
Always use battery selector switch position “1” or “2” when
AC power is supplied to the battery charger.
NOTICE
If a 120 (220) volt battery charger is used, be
sure the neutral lead of the charger is isolated
from the ground or bonding circuit. Be sure the
battery charger is of the type which properly
senses battery requirements and does not over-
charge or cause the electrolyte to boil.
Microwave - The MICROWAVE breaker must be ON to
supply power to the microwave on the 278 model. The
microwave on the 238 and 258 models is protected by
the OUTLET breaker.
Receptacles - The OUTLET circuit breaker supply power
to all receptacles (except the microwave and refrigerator
on the 278 model).
Most receptacle circuits are capable of handling 15 am-
peres. Refer to Table III for a list of equipment and the
electrical currents usually required to operate these items.
For 220 volt, 50 Hertz models, divide all of the current
ratings below by 2. Usually, the power requirement is
specified on the electrical item. This is only an ap-
proximation of the electric current usage normally experi-
enced.
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 E-8c Reverse Polarity Indi-
cator.
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
system (except the refrigerator which is dual voltage).
Appropriately labeled circuit breakers protect the micro-
wave, charger, receptacles, and electric water heater. The
receptacles can be used for 120 volt (220 volts on 50
Hertz models) household appliances. Refer to the follow-
ing list for information on appliances and other equipment.
NOTICE
On earlier Vista models, the refrigerator operated
on 12 Volt DC system only. With shore power
on, the battery charger supplies power for the 12
volt system and maintains charge on the batter-
ies. On later models, the refrigerator is set up
for both systems.
