Never operate 120 volt shore power at less than 110
volts.
! CAUTION
EXTREME HAZARD – Swimming near a boat
operating on AC electrical system can lead to severe
shock and death. Never swim or allow swimming
when AC system is in use.
! DANGER
Under no circumstances override the source
select system.

NOTE: Actual usage of equipment will depend on
the amperage output of the power source available.
Line voltage from the generator or shore power is
shown by the voltmeter on the main distribution
panel.
When equipped with generator option the main
distribution panel main breakers are equipped with
a source selector slide to prevent the generator and
shore power from being energized at the same time
and damaging the electrical system. Both breakers
must be in the OFF position before switching to an
alternate power source.
The main breakers may trip if there is a surge in
line voltage, an electrical storm or an onboard
system overload. The main breaker interrupts both
the neutral and hot feeds in the AC circuit to prevent
equipment damage due to internal overloads and
external surges.
120 Volt / 60 Hz Wiring (Standard System)
The 120 volt wiring installed on Sea Ray ® boats
consists of three (3) color-coded wires. The black
wire is the “hot” feed, white is the common, or
neutral, and the green wire is the ground. All branch
breakers and switches for AC equipment are
installed on the “hot” wire. The green conductor of
the shore power is connected through the galvanic
isolator and then connected to the AC grounding
bus bar behind the main distribution panel.
220 Volt / 50 Hz Wiring (Optional System)
The 220 volt / 50Hz wiring installed on Sea Ray
®
boats consists of three (3) color-coded wires. The
brown wire is the “hot” feed, light blue is the
common, or neutral, and the green wire is the
ground. All branch breakers and switches for AC
equipment are installed on the “hot” wire. The green
conductor of the shore power is connected through
the galvanic isolator and then connected to the AC
grounding bus bar behind the main distribution
panel.
Never operate 220 volt shore power at less than 205
volts.
