There are two ways to provide shore power.
A single 30A 125V shore power cable
plugged in to
SHORE POWER INLET
1
in the transom (shown in the adjacent photograph) will provide power to
breakers at the left side of the 120V
AC panel
.
Two 30A 125V shore power cables
connected to 30A 125V volt sockets
at the dock
and plugged into SHORE POWER INLET 1 AND SHORE POWER
INLET 2 will provide power to breakers on both sides of the
120V
AC panel
. The
transfer switch should be off. Even if it is on, 120V AC won’t be transferred
to the left panel from the right panel.
Instead of two 30A 125V volt sockets at the dock, there may be a single
50A 225V socket. In that case, use a Y adapter that splits the power for
two 30A 125V shore power cables. (See adjacent image.)
Charging
The batteries will accept a charge from 120V shore power
through the
INVERTER/CHARGER if SHORE POWER 1 is on
even if the
HOUSE BATTERY
switch is
off
.
Transfer Switch
If
SHORE POWER 2
isn’t connected, the
TRANSFER
SWITCH
transfers power from the left side of the
120V AC BREAKER panel
to
the right side. However, the circuits on the right side are for high amp
loads. If you use the
TRANSFER SWITCH
with
SHORE POWER 1
alone, the
circuits that can be successfully powered are limited. Operating the
AIR
CONDITIONING
, the
COOKTOP
and the
WATER HEATER
together would
overload the circuit.
If you overload the shore power circuit and trip the breaker you may reset it
by pushing the switches on the
SHORE POWER BREAKER BOX. It’s
outboard under the port cockpit hatch cover. (See sidebar.)
If you plan to use more than one of the
AIR CONDITIONING
systems at the
same time,
it would be best to supply
the circuits on the right side of the
panel with the
GENERATOR
or
SHORE POWER
2 that bypasses the
INVERTER/CHARGER
. The left side 120V AC circuits may also be supplied
from the
HOUSE BATTERIES
with the
INVERTER/CHARGER
. (See page 25.)

OUR
C
IRCUITS
The connection block for the 24-hour circuits is forward in the starboard
pilothouse settee locker.
The 24-hour circuits (shown in the sidebar)
bypass the breaker panel,
HOUSE, ENGINE and GENERATOR switches
and
are connected directly to the
HOUSE BATTERY
. They are:
•
BILGE PUMPS (3 connections)
•
HIGH WATER ALARM
•
EMERGENCY PARALLEL
• STEREO MEMORY
The
EMERGENCY PARALLEL
connection enables the EMERGENCY
PARALLEL switch on the 12V DC panel. The
STEREO MEMORY connection
provides a trickle charge to maintain the clocks and user settings.
Disconnecting shore power with
INVERTER
left
on
will
discharge the
HOUSE BATTERIES over time
. (See page 25.)
SHORE POWER INLET 1
is
connected. None at
SHORE POWER
INLET 2
. The receptacle on right is for
Ethernet and coax TV connections.
SHORE POWER BREAKER BOX
A Y adapter can split 50A 220V shore
power to two 30A 125V shore power
cables.
