Reverse Polarity Indicator; Ground Fault Current Interrupter - Four winns 378 Vista Owner's Manual

Icemaker - The ICEMAKER breaker must be ON to sup-
ply 120 VAC power to the icemaker. The icemaker is
standard on the 378 Vista™.
Receptacles - The OUTLET circuit breakers supply power
to the corresponding receptacles in the AC system.
Air Conditioner - The AIR CONDITIONER (AC SYSTEM
2) circuit consist of two of MAIN circuit breakers which
allow power to flow to the air conditioner. Both breakers
must be in the ON position for air conditioner operation
when using dockside power. Dual Dockside is installed
on the 378 which allows independent power to be sup-
plied to the air conditioner. Refer to Section L-4 - Air
Conditioning in this manual for more information.
Most receptacle circuits are capable of handling 15 am-
peres. Refer to Table I 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.

C. Reverse Polarity Indicator
Improper grounds or reversed polarity at shore power are
a source of serious electrical hazard. The reverse polar-
ity light will indicate if a problem exists at the 120 AC
electrical system shore connection
.
If a problem exists, the reverse polarity indicator light will
come on when the shore power cable is attached to the
378 Vista™ Owner's Manual

inlet. DO NOT activate the shore power breaker switch
on the main AC panel when the Reverse Polarity light is
on.
ALWAYS check the reverse polarity indicator
light in the AC distribution panel immediately
upon connecting the shore power cord before turn-
ing on the AC SHORE POWER circuit breaker.
If the light is on, a problem with a reversed elec-
trical connection exists. Disconnect the shore
power cord immediately. Notify the marina and
have the dock's shore power connection inspect-
ed.
Under proper operating conditions, the reverse polarity
indicator light will not be on. A green light is provided for
the shore power and will be ON when dockside power is
connected.
NOTICE
Some marina shore power systems may be im-
properly grounded to retard electrolysis (see Sec-
tion H-9 - Stray Current Corrosion). Before us-
ing any 120 volt equipment, make sure the re-
verse polarity 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 protects against hazardous electrical shock from
improper ground. An appliance electrical cord with worn
insulation or damp equipment may have stray 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 receptacles on
the circuit. A GFCI may be used as a receptacle as well
as an interrupter.
To test:
Push the black test button and the red reset button should
pop out from the inner surface. The receptacle 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 equip-
ment being used, or a ground fault in the equipment.
Unplug all appliances and reset the GFCI. One at a time,
plug the equipment back in and turn it on. The item that
