3.0 AC Electrical System
Your boat is equipped with a 30 amp AC (alternating current) electrical
system. The power for this system is supplied by either a shore power
source or the generator. The procedures for connecting to a shore power
source and to the generator are explained later in this section.
3.1 System Organization
The AC electrical system is divided into two circuits: Line 1 and Line 2.
If your boat was built for use in North America or the Pacific Rim, each
line is configured as 120 volts 60 Hertz. If your boat was built for use in
Europe or Australia, each line is configured as 220 volts 50 Hertz.
Line 1 provides power to all of your boat’s AC equipment except for the
air conditioning system. Line 2 provides power to the air conditioning
system.
3.1.1 Wiring System
The AC electrical system on your boat uses three types of color-coded
wires.
The black wire carries the current from the power source to the equip-
ment or receptacle. Each black wire is connected to and protected by a
circuit breaker installed in the AC Control Center.
The white wire returns the current from the equipment or receptacle to
the power source.
Safety ground wires are green. During normal operation, current does
not flow through the ground wires.
Buss bars are used in the AC electrical system to help route and organize
the wires. The system’s white, or neutral, wires are connected together
at buss bars. The ground wires are also connected together at a separate
buss bar.
Do not touch the black or white wires while the AC electrical system is
connected to a power source. These wires carry enough current to kill
or cause serious injury.
