! DANGER
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.
The 44 DB's AC electrical system operates on a
dual 120V/60 cycle, 30 amp shore power system
or the onboard 120V/60 cycle generator.
Take time to become familiar with the Main
Distribution Panel in the port salon.
NOTE: Actual usage of equipment will depend on
the amperage output of the power source available.

through the selected power source's circuit
breakers on the main distribution panel.
The main breakers located on the AC Main
Distribution Panel (See figure 6.11.1) receive power
through a source selector slide. This selector
prevents the generator and shore power from being
energized at the same time and damaging the
electrical system. Both generator and shore power
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

Never operate 120 volt shore power at less than 105
volts.
equipment damage due to internal overloads and
external surges.
The 120 volt wiring installed on Sea Ray
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 isolation
transformers to the AC grounding bus bar behind
the main distribution panel.
NOTE: The 220V/50Hz European (CE) option uses
Brown (Hot),Lt. Blue (Neutral) and Green (Ground)
wiring.
