CAUTION
! !
Never reset a breaker which has tripped automati-
cally without locting and correcting the problem.
Electrical system and devices may be damaged.
Faulty connections can cause a fire. Correct the
cause before resetting the breaker.
When the GENERATOR indicating light is ON and its
breaker is ON, AC power is supplied to the equipment
and devices below it. The slide bar prevents power from
being supplied by shore power when the generator is
providing power.
The ACCESSORY slots are for any additional AC equip-
ment you may add to your boat.
Note: Before you add additional items to the boat's elec-
trical system, ask your dealer to analyze your boat's AC
and DC systems.
8.1.1 Shore Power Supply
Your boat has two shore power inlets, one on the tran-
som and one in the anchor locker. A 50 amp 120 volt line
supplies power to the AC control center in the salon. Next
to the shore power inlet plug is a circuit breaker for the
power connection.
Besides the generator, still another source of AC power
is your Inverter. The Inverter takes DC power from your
batteries, and transforms it to AC power.
DANGER
! !
Never work on an energized circuit! Always treat any
circuit as if it were live! Always have trained compe-
tent technicians to service your electrical systems!
Water is an excellent conductor of electricity. Keep
shore power cord out of water. Do not operate any
AC device while you or the cord are in the water. To
prevent injury or equipment damage, keep all AC
system components dry.
CAUTION
! !
Be certain the water heater is full of water and does
not contain air. If the water heater is not full of wa-
ter damage to the heating elements may result when
electrical power is turned on to the unit.
AC Electric System
Besides a 12 VDC negative ground system, your boat
has a 120 V 60 Hz (220/230 V 50 Hz) AC system. This
section gives you the basic knowledge you will need to
understand this system.
The AC System consists of the following systems or
components:
AC Distribution Panel
Shore Power Supply
Generator Power Supply (Option)
Battery Charger
Refrigerator
Microwave
Coffee Maker
Water Heater
Galley Stove
Stereo, TV, DVD
Air Conditioning Units
8.1 Power Supply Components
The AC system is a three-wire grounded system powered
by either the shore power or genertor (if so equipped). A
circuit breaker for the shore power connection is on the
transom just above the shore power coed plug.
There is a ground fault interruption circuit (GFIC) that
protects all outlets. This system prevents accidental elec-
trical shock. If power is lost to an outlet, reset the breaker
at the GFIC outlet.
Important: If you cannot reset GFIC outlet, do not use
any other outlets to prevent damage to the electrical sys-
tem or electrical devices. Have your dealer or qualified
electrician check the circuit.
Circuit breaker on the main electrical panel controls
and protects the AC circuits. The legend for the AC
Distribution Panel is on page 8 and 9 of this chapter. The
circuit breaker must be ON to power each AC device. A
brief discussion of the purpose of several of the breakers
at this panel follows. The remaining breakers, switches
and indicators are discussed with the systems or equip-
ment they control.
