Electrical System
Notice:
When only one 30 amp dockside outlet is
available, always connect the shore power
cord to the Shore 1 inlet connection. Then
use the Transfer main breaker to energize
Shore 2. If the shore power cord is connect-
ed to Shore 2, the sliding cover will prevent
the Transfer breaker from being activated
to energize the Shore 1 circuits.
Care must be taken when operating the AC sys-
tem from the generator or only one 30 amp shore
power supply line. On some boats it may be pos-
sible to overload the generator or shore power
circuit if too many AC accessory breakers are
activated. You should be aware of the load each
accessory draws and make sure you don’t overload
the circuit. Overloading the circuit can damage
accessories and cause Shore main or Genera-
tor breaker to trip. This is particularly important
when operating the water heater or optional air
conditioner units. You should always be aware of
the electrical load needed to activate accessories
and manage the amperage being supplied so the
load can be kept within safe limits.
The table at the end of this section will assist you
in documenting the load AC accessories on your
boat require and managing the electrical load
on the circuit. If you have any questions about
managing the power in your boat, contact your
Monterey dealer.
Reversed Polarity Lights
The red lights indicate reverse polarity current
supplied to the panel for each circuit. This situa-
tion will cause the red light to remain lit. If reverse
polarity is achieved, immediately turn off all cabin
AC breakers and dockside outlet breakers. Dis-
connect the power cable from the dockside outlet
and notify a qualified marine electrician to check
the dockside wiring.
Reverse Polarity Light Test Switch
There is a momentary switch located next to the
reverse polarity lights in the AC breaker panel.
This switch is used to test the reverse polarity
lights to ensure they are functioning. The lights
can be tested by depressing the switch whenever
the AC system is activated. The reverse polarity
lights should be tested each time the AC system
is activated. If the light does not activate when
the switch is pressed, disconnect the shore power
cable and notify a qualified electrician to check the
light and the dockside wiring if necessary.
AC Accessory Circuit Breakers
Stove
Supplies 120/220 volt AC electrical current to the
stove in the galley.
Outlets
Supplies 120/220 volt AC electrical current to the
ground fault interrupter (GFI) electrical outlets.
Notice:
All AC electrical outlets are provided with
ground fault interrupts to protect against
electric shock. These outlets should be
tested periodically to ensure proper opera-
tion by pressing the test/reset buttons in
the center of faceplate. GFI outlets do not
protect against short circuits and overloads.
This is done by the outlet breakers on the
AC panel.
WARNING
GFI OUTLETS DO NOT PROVIDE 100% PROTECTION FROM
ELECTRIC SHOCK. EVEN THOUGH GROUND FAULT
INTERRUPTERS PROVIDE PROTECTION BY REDUCING
EXPOSURE TIME FROM LINE TO GROUND SHOCK HAZARDS,
IT IS STILL POSSIBLE TO RECEIVE AN ELECTRIC SHOCK
FROM DEFECTIVE APPLIANCES OR POWER TOOLS AND
MISUSED ELECTRICAL EQUIPMENT.
Water Heater
Supplies electrical current directly to the hot water
heater circuit. A thermostat in the water heater
control panel automatically controls the water
temperature. Before operation, you must have
water in the water heater. (See the water heater
manual for details)
Battery Charger
Supplies electrical current directly to the automat-
ic battery charger. The battery charger recharges
and maintains the 12 volt batteries simultane-
ously when activated. It is fully automatic. See
the battery charger manual for more information.
The charge to the engine batteries can be moni-
tored by using the volt meters in the engine gauge
cluster. To monitor the engine batteries, activate
the charger and turn the engine battery switches
on. Turn the ignition key switch for each engine
to the ON position (DO NOT START THE EN-
GINES) and read the voltage on the volt meter
for each engine. To monitor the house batteries,
activate the charger and turn the HOUSE battery
switch on. Read the volt meter in the cabin DC
