NOTICE
Some ma rina shore pow er sys tems may be
im pro perly gro und ed to re tard elec troly sis
(see Sec tion H-11 - Stray Current Corrosion).
Be fore us ing any 120 volt equi p m ent, make
sure the re ve rse po larity light does not activate
when con necting the cord to the inlet.
D. Ground Fault Current Interrupters (GFCI)
The ground fault current interrupter (GFCI) is a device
which pro tects against hazardous electri cal shock
from improper ground. An appliance electri cal cord
with worn insula tion or damp equip ment may have
s tray current which will run through electrical grounds.
Stray current as above will result in an electrical
shock.
One GFCI receptacle will protect all of the recep ta cles
on the circuit. A GFCI may be used as a recep tacle as
well as an inter rupter.
To test:
Push the black test button and the red reset button
should pop out from the inner surface. The recep tacle
and the circuit are now off.
Push the reset button in until it clicks to reset it. If it
does not reset, there is either a short in the circuit or
the equipment being used, or a ground fault in the
equipment. Unplug all appliances and reset the GFCI.
One at a time, plug the equip ment back in and turn it
on. The item that caus es the GFCI to trip is the
problem item and should not be used.
H - 9 GENERATOR
A generator is optional on the 338 Vista
provides 120 Volt (220V) AC power when the boat is
away from the dock. The gener ator can be operated
while running at or below cruising speed. The genera-
tor should not be operated when the boat is being run
at high speeds. Insufficient cooling water may be
avail able due to the speed.
A generator factory installed by Four Winns is capable
of providing sufficient power for most electrical needs
including cooking, refrigeration, and air conditioning.
It is possible to overload the generator by trying
to operate too much equip ment at one time. The
circuit breaker that protects the output cir cuits on the
generator set will trip should that occur. See the
Electrical Systems - Section H
generator manu facturers information for specifications
and addi tional de tails.
If you wish to use dock side power, be sure the genera-
tor is off, connect the shore power cords as explained
in Section H-8A, and turn on the Shore Power breakers
on the AC cabin panel. If you wish to use generator
power:
1. Be sure the shore power cord(s) are dis con nected.
2. Check the bilge for fumes, operate the blower for at
least 4 minutes, and verify blower operation.
3. Open the generator's seacock valve (labeled
GENERATOR) to allow water flow to the generator
for cooling purposes.
In order to use the generator, you must first
open the seacock valve (handle parallel to the
flow of valve). Failure to open seacock valve
while running generator will cause generator to
overheat and possible failure. When not using
the generator be sure to close the seacock.
4. Start the generator using the remote gen erator start
switch on the AC/DC cabin panel.
5. Turn on the generator's main breakers located in the
AC cabin panel.
Be sure to operate the bilge blower for at least
four (4) minutes before starting engine or
generator, or whenever operating the engine(s)
at idle speed. Check the bilge blower output
before each use.

Generator exhaust contains carbon monoxide.
Review information regarding carbon
monoxide at Section B-2 - Carbon Monoxide
and Section E-2 - Engine Exhaust.
Periodic generator maintenance as outlined in the
generator owner's manual is necessary. Refer to the
manufacturer's literature for more information. General
generator installation diagrams are included at the end
of this section.
