air conditioning. The dockside system uses three-wire,
color-cod ed circuitry. The black or hot wire is the
un grounded current carrying conductor. The white
or neutral wire is the grounded current carrying
conductor. The green wire, referred to as the “equip-
ment ground,” is a grounded conductor, and under
normal conditions is not a current carrying wire.
The neutral wires are connected together at a buss
bar. The equipment grounds are similarly connect ed
together at another buss bar. Each hot wire is con-
nected to, and protect ed by, a circuit breaker in the
distribu tion box located at the top section of the
AC/DC cabin panel identified “120V AC SYSTEM”.
The standard dockside system has a main circuit
breaker which protects the overall distribution network.
The MAIN dockside inlets are located in the aft
transom systems locker. The 358 Vista
®
models have
MAIN circuit breakers on the AC/DC cabin panel.
The MAIN breakers must be turned “ON” and the boat
must be connected either to shore power or generator
running for AC system operation. The MAIN circuit
breakers protects both the hot and neutral input leads.
This breaker is sensitive. The resulting power surge
which occurs when connect ing the shore power cord
may cause the MAIN breakers to trip. To avoid this
power spike, turn off the MAIN break ers before
plugging in the shore power cord. Securely connect
the power inlet of the boat and the shore power
receptacle. Once the shore power is securely
connected, turn the MAIN breakers back on. If the
connection is broken and later re-secured, the circuit
breaker may trip. Connections must be secure for
unin terrupt ed dockside service.
The AC voltage for the generator, or shore power AC
systems 1 or 2, may be monitored with the AC
voltmeter in the AC/DC panel. Use the AC source
toggle switch to monitor the voltage of the system
desired.
H - 8 DOCKSIDE OPERATION
If any abnormalities appear during dock side
operation, DISCONNECT the sys tem immedi-
ately to prevent electric shock hazards! Have
the boat’s electrical sys tem and the shoreside
recep tacles checked as soon as possible.
A. Shore Power Connections
To prevent electric shock hazards, use only
equ ip ment with ap pro ved three wire elec trical
plug con nec tio ns. Be sure each item be ing
used has been test ed 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 twist-
lock-type receptacles. An adaptor is avail able from
Four Winns which converts the twistl ock shore plug to
a three wire grounded house hold type plug. Use only
an approved adaptor when an adaptor is necessary.
DO NOT use a two-wire adaptor to con nect to
a three-wire system. These adapt ers do not
provide adequate groun ding.
Shore power connection procedure is as follows:
1. Turn off the 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 con nect the cord to the power inlet
recep tacle 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 discon nect the shore power cord.
See Section H-8C - 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 receptacle first. Then, dis con nect the
cord from the boat.
