Electrical System

OS 315
The AC system is powered by the shore
power or by the generator. Your boat is
equipped with an isolation transformer. The
isolation transformer maintains correct AC
polarity regardless of the polarity of the
shore power supply and eliminates the need
for a galvanic isolation system. Refer to the
isolation transformer manual for additional
information.
All AC current is distributed to the AC com-
ponents through individual circuit breakers
located in the AC panel. The main breaker in
the panel protects the system from an over-
load.
4.5 AC Main Distribution
To reduce the possibility of an electrical
shock, it is important that the AC ground sys-
tem is functioning properly and that a proper
connection exists between the shore power
cord, the shore power inlet, the boat bonding
system and the outlet ground circuits. If
there is any doubt about the integrity of the
ground circuit, a qualified marine electrician
should be contacted immediately and the
AC should be disconnected until the neces-
sary repairs are completed.
The AC panel is located in the cabin. The
following are descriptions of the AC panel
equipment and the breakers that protect the
accessories:
AC Ammeter
Indicates the total amperage or current
being drawn through the AC panel. It is the
total current level of all of the AC equipment
in operation at the time.
AC Volt Meter
Indicates the voltage supplied to the panel.
AC Main Breaker
Protects the general distribution network.
This breaker is very sensitive. The resulting
power surge that occurs when connecting
the dockside cord may cause the main
breaker to trip. To avoid this surge, turn the
main breaker to "OFF" position before plug-
ging or unplugging the shore power cord.
Microwave
Supplies AC directly to the microwave oven.
Refer to the microwave manual for more
information.
Stove
Supplies AC to the galley stove. Refer to the
stove manual for more information.
Battery Charger
Supplies AC directly to the battery charger.
Outlets
Supplies AC to the cabin electrical 120-volt
outlets. AC electrical outlets are provided
with ground fault interrupters (GFI) to help
protect against electric shock. Test outlets
periodically by pressing the test/reset but-
tons in the center of the face plate to ensure
proper operation. GFI outlets do not protect
against short circuits and overloads. This
protection is done by the outlet breakers on
the AC panel.
GFI outlets do not provide 100% protection
from electric shock. Even though GFI outlets
protect by reducing exposure time from line
to ground shock hazards, it is still possible to
receive an electric shock from defective
appliances, power tools or misused electri-
cal equipment.
Air Conditioner (Optional)
Supplies AC directly to the air conditioning
control panel and the air conditioner raw
water pump (if option is installed). Otherwise
it is reserved for additional AC equipment.
This breaker will trip if raw water is not being
supplied to the air conditioner. If this breaker
trips, reset and check for water flow out of
the air conditioning thru-hull. Refer to the air
conditioner manual for additional informa-
tion.
