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.
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
buss bar behind the main distribution panel.
Never operate 120 volt shore power at less than 105
volts.
