•
Electrical Panel:
is built by Bass and controls electric distribution with circuit breakers and
switches. The main wiring harness runs from the back of this panel.
•
Mast Wiring Terminal Box:
is located in the shower compartment on the bulkhead. A wiring
harness exits the mast near the box, and is wired directly into the D.C. system through a terminal
strip. Once this wiring is installed, test each function to insure proper operation.
•
Battery Switch:
The battery switches (one for each house bank) are located under the navigation
table. They operate in either an ON or OFF position. The dedicated engine battery switch is
located in the aft cabin with a similar switch.
• There is a waterproof
Momentary Parallel Switch
located in the cockpit at the engine panel. The
purpose of this switch is to allow you to start the engine using the house bank should the
dedicated engine battery fail.
• The
Alternator
is attached to the engine and creates a charging current only when the engine is
running. The output is to an automatic battery system located in the aft hanging locker which
distributes the current to the batteries as deemed necessary.
•
Accessories:
such as navigation instruments, stereos, radars, GPS can be added to the electrical
panel and the 12 VDC system. Extreme care and forethought is necessary for installation as these
are sensitive instruments and require some measure of protection. Such work should be performed
by a marine electrician. Be sure all sensitive accessories are not only grounded properly but that
“fast blow” fuses are run off the panel for extra insurance against damage to their components.
110 VAC Shorepower System
The 110 volt AC shore power system is functional only when the boat is plugged into suitable power from
shore. The cord provided as part of the option has the standard end for 50 amperage service. Depending
on the wiring in the facility, various adapters may be required to plug into the shore end. The boat end of
the cord plugs into the inlet on the starboard cockpit coaming. Ensure the plug prongs match those on the
inlet, insert and twist to lock it. Then screw down the outer ring to seal the cord from water and to prevent it
from pulling out. The AC panel for shore power is located in the nav station as part of the primary panel.
Due to the length of the wire run from the inlet to the electrical panel, there is a circuit breaker located aft of
starboard cabin bulkhead. This switch needs to be on in order for shore power to reach the panel.
•
AC Selector Switch:
is located on the main electrical panel. This switch has settings for SHIP
service (inverter or generator) or, SHORE service (dockside). To activate AC power, use this
switch to select the source.
•
AC Side of the Panel:
indicates line voltage being received from the shore circuit with an indicator
light. The line voltage will vary with the number of appliances operating on the same circuit. In
large marinas there may be a large number of boats on the same circuit, causing fluctuations
•
AC Normal/AC Reverse Polarity Light
: The AC side of the panel has a red light to show when
the polarity is reversed. Care should be taken not to operate 110 AC systems on board with
reversed polarity. Double-check shore connections. If problems still persist, then notify dock
master to repair the shore plug. NOTE- Even though the switches are in the appropriate position,
the shore power system in no way assures personal safety using electrical apparatus.
•
Water Heater:
switch supplies power to the water heater 110 AC element for hot water while
dockside. Note the precautions regarding the use of electrical power to heat water are contained
in the plumbing section of this manual.
•
Outlets:
located throughout the cabin supply power for 110 AC accessories. The entire system
has “ground fault” protection.
•
Ground Fault Systems:
There are two separate ground fault systems: 1) One in the nav station
to protect the outlets to starboard. 2) One in the galley protecting outlets to port.
