4.5 Seakeeper Gyro (optional)
Your boat may be equipped with an optional
Seakeeper
®
gyroscopic stabilization system.
Please refer to the Seakeeper owner’s man-
ual for information about the operation of this
system.
4.6 AC System
Either shore power or generator power may
be used to supply AC current to the AC distri -
bution panel, located
in the starboard cabin
upper electrical cabinet
. All AC current is dis -
tributed to AC components through individual
120V (230V for CE) circuit breakers located
on the AC distribution panel.
The AC electrical system operates on a 120
volt, 30 amp, 60 Hz system. The AC system
is fed by shore power or by the generator.
An isolation transformer maintains correct AC
polarity regardless of the polarity of the shore
power supply, and eliminates the need for a
galvanic isolation system and reverse polar-
ity indicator. Refer to the isolation transformer
manual for additional information.
DANGER
!
ELECTROCUTION, FIRE OR
EXPLOSION HAZARD
Contact with live wires or working on
an energized electrical system can
cause electrocution. It can also cause
sparks, resulting in fire and/or explo -
sion. Both cases will result in death
or serious injury. DO NOT work on an
energized system or allow unqualified
personnel to work on the system.
Shore power and aux power/generator
select switch and polarity indicator lights
(typical)
The power selector breakers in the AC dis -
tribution panel are equipped with a selector
slide to prevent the shore power source and
the generator source from being energized
simultaneously and damaging the electrical
system components. Refer to further informa -
tion about shore and generator power later in
this section.
4.7 AC Distribution Panel
The AC distribution panel is located in the
starboard cabin upper electrical cabinet.
