NOTE:
Actual usage of equipment will depend on
the amperage output of the power source available.
Line voltage from the shore power is shown by the
voltmeter on the main distribution panel. 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.
