Transom Shower Dockside Inlets TV/Phone
The boat is equipped with 30 amp, 120 volt, 60 Hertz (or
15
amp, 220 volt, 50 Hertz) AC electrical wiring. When
the boat is connected to a shore power outlet, the AC
system supplies electrical power to the following items:
battery charger, refrigerator, water heater, range, micro-
wave, icemaker, and outlets.The air conditioner has its
own dockside power plug. The dockside system uses
three-wire, color-coded circuitry. The black or hot wire is
theungroundedcurrentcarryingconductor. Thewhiteor
neutral wire is the grounded current carrying conductor.
The green wire, referred to as the “equipment ground,” is
a grounded conductor, and under normal conditions is
not a current carrying wire. The neutral wires are con-
nected together at a buss bar. The equipment grounds
aresimilarlyconnectedtogetheratanotherbussbar. Each

dockside inlets are in the aft shore power tub. See
Figure H3. The 378 has a MAIN circuit breaker located
underneath the starboard cockpit aft seat which must
be in the “ON” position in order to indicate a reverse
polarity situation. See Figure H4. Also, a second set
of MAIN circuit breakers are located on the AC cabin
panel. Both MAIN breakers must be turned “ON” forAC
system operation. The MAIN circuit breaker protects
both the hot and neutral input leads. This breaker is
sensitive. The resulting power surge which occurs when
connecting the shore power cord may cause the MAIN
breaker to trip. To avoid this power spike, ensure the
MAIN breaker at theAC cabin panel is turned off before
plugging in the shore power cord. Securely connect the
power inlet of the boat and the shore power receptacle.
Once the shore power is securely connected, turn the
MAIN breaker on. If the connection is broken and later
re-secured, the circuit breaker may trip. Connections
must be secure for uninterrupted dockside service.
