Electrical System
Shore 1, Shore 2 and Generator Main Breakers
(Boats Equipped With Optional Air Conditioning)
If your boat is equipped with optional air condition-
ing, the AC system will include two power cords
and inlet connectors. One cord supplies Shore
main breaker 1 and the other cord supplies Shore
main breaker 2. These breakers select the power
source and protect the general distribution net-
work. If your boat is not equipped with an optional
generator, there will only be a Shore main breaker
for each main circuit and a Transfer main breaker.
If your boat is equipped with a generator, there
will be a Shore and Generator breaker for the
Shore 1 circuit and a Shore and Transfer breaker
for Shore circuit 2. A sliding safety cover on the
main breakers prevents activating the generator
and shore circuits or the Shore 2 and Transfer
circuits simultaneously. These breakers are very
sensitive. The resulting power surge that occurs
when connecting the dockside cords may cause
the main breakers to trip. To avoid this surge,
always turn the Shore Power main breakers to
the OFF position before plugging or unplugging
the shore power cords and the Generator breaker
to the OFF position when starting the generator.
If your boat is equipped with the optional genera-
tor, the main breakers are used to select either
shore power or the generator to supply 120/220
volt power to the AC breaker panel. When con-
nected to dockside power, move each sliding cover
to the shore power position and activate the Shore
1 and Shore 2 main breakers. When using the
generator, move the Shore 1 sliding cover to the
generator position and activate the Generator
main breaker. Move the Shore 2 sliding cover
to the transfer position and activate the Transfer
main breaker to connect 120/220 volt power from
the generator to the Shore 2 circuits. The main
breakers must be in the OFF position before the
sliding covers can be moved to the Generator,
Transfer or Shore power positions.
Transfer Main Breaker
The transfer circuit breaker is located next to the
Shore 2 main breaker. It is used to connect the
Shore 1 circuit and the Shore 2 circuits together
to energize the entire 120/220 volt distribution
network when only one 30 amp dockside outlet is
available or while operating the generator.
