Basic Systems Operation
AC Electrical System
AC POWER
The standard AC electrical system in the
430 Sports Coupe
is wired
for 120/240V AC, 50-amp, single-phase, 60-hertz power. This allows
the system to have two lines, L1 and L2, at 120V AC and also 240V
AC. The neutral (white) conductor is connected to shore grounded
neutral. The yacht ground (green wire) is connected to the dockside
ground via a galvanic isolator. The galvanic isolator reduces galvanic
corrosion due to stray low-voltage DC currents between the yacht
ground and the dockside earth ground.
An optional AC system for non-US power is wired for 220-volt,
32-amp, 50-hertz power.
AC Master Panel
United States Version
120/240V AC, 50-amp, 60-hertz single-phase is the standard power
system. An onboard generator will furnish 120/240V AC single-phase
power.
International Version
220V AC, 32-amp, 50-hertz single-phase is the optional international
power system. An onboard generator will furnish 220V AC, 50-hertz
power.
The load center can receive power from dockside or the generator.
For dockside power, move the slide protector over the generator
breaker and turn on the dockside breaker. For generator power, move
the slide protector over the dockside breaker and turn the generator
breaker ON.
The circuit breakers’ function is twofold: they allow you to manually
enable or interrupt a circuit by flipping the switch to ON or OFF, and
they also protect the system receiving the AC load by automatically
breaking the circuit in case of shorts or overloads.

DANGER
Considerable care has been taken to design a safe
electrical system to protect you from hazardous
shocks. Any modifications to the system should
always be done by an authorized Cruisers Yachts
Dealer not only to protect your warranty, but to protect
you from hazardous shock as well.
CAUTION
DO NOT reset a breaker which has been automatically
tripped without first identifying and remedying the
cause of the problem.
IMPORTANT
Read the generator owner’s manual contained in the
Skipper’s Kit before operating the generator for the first
time. The manual contains important operation and
maintenance information.
