Stereo - The stereo has a separate switch on the unit
and is protected by a circuit breaker labeled STEREO
on the 12 volt cabin panel of the 248/268.
Sump Pump - A sump pump is used to discharge water
from the shower and sink drains overboard. It is in-
stalled on all Vistas. The sump pump has a float switch
which will activate the pump when the water level rises
in the sump. This pump is protected by the SUMP fuse
located at the helm.
If the boat is equipped with a grey water system, the
water from the shower and sinks is pumped into a hold-
ing tank instead of overboard.

120 (220) VOLT ELECTRICAL SYSTEM
The boat is equipped with 30 amp, 120 volt, 60 Hertz (or
15 amp, 220 volt, 50 Hertz) AC electrical wiring. When
the boat is connected to a shore power outlet, the AC
system supplies electrical power to the following items:
battery charger, refrigerator, water heater, range, mi-
crowave, outlets, and air conditioning. The dockside
system uses three-wire, color-coded circuitry. The black
or hot wire is the ungrounded current carrying conduc-
tor. The white or neutral wire is the grounded current
carrying conductor. The green wire, referred to as the
“equipment ground,” is a grounded conductor, and un-
der normal conditions is not a current carrying wire. The
neutral wires are connected together at a buss bar. The
equipment grounds are similarly connected together at
another buss bar. Each hot wire is connected to, and
protected by, a circuit breaker in the distribution box.
The standard dockside system has a main circuit breaker
which protects the overall distribution network. The 248/
268’s MAIN dockside inlet is on the port side of the
deck.
The MAIN circuit breaker protects both the hot
and neutral input leads. This breaker is sensitive. The
resulting power surge which occurs when connecting
the shore power cord may cause the MAIN breaker to
trip. To avoid this power spike, turn off the MAIN break-
er 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 con-
nected, turn the MAIN breaker back on. If the connec-
tion is broken and later re-secured, the circuit breaker
may trip. Connections must be secure for uninterrupted
dockside service.

DOCKSIDE OPERATION
If any abnormalities appear during dockside op-
eration, DISCONNECT the system immediately
to prevent electric shock hazards! Have the
boat’s electrical system and the shoreside recep-
tacles checked as soon as possible.
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 con-
nectors. This connector is approved by National Marine
Manufacturers 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.
