TYPICAL AC MAIN AC CONTROL PANEL
REVERSE POLARITY INDICATOR
Before activating the panel main breaker visually check for
a green light at the reverse polarity indicator. The green
light indicates there is no reverse polarity. If the red light
appears on the revese polarity indicator a hot wire and
ground may be reversed somewhere in the circuit from
the dock to the main panel or there may be an overcur-
rent condition. Check the ELCI breaker as it will “trip” if
a reversed polarity situation develops.
In all cases do not activate the main panel breaker. Take
immediate corrective action to fi nd the cause of the re-
verse polarity situation. At this point, disconnect the
shorepower cord from the marina power center and call
for professional assistance.
PANEL MAIN BREAKERS
The main panel breakers for Leg A and Leg B also called
shore power 1 and shore power 2 deliver electricity
through a system of sub breakers to the entire boat. Turn
any sub breakers found “on” to the “off ” position. This
prevents any excessive equipment motor draws and may
eliminate any system arcing.
With the reverse polarity indicator showing the green icon,
activate the main breaker by pushing the single throw arm
to the on position. Notice that each breaker is marked
with the on and off terminology, AC electricity now is
distributed to the 120 volt leg B of the panel. Follow the
same procedure for the main breaker for leg A.
Turn on sub breakers as needed always being conscious
of the load current meters..
50 AMP AC GENERATOR BREAKER
When the boat is under generator power AC electricity
is distributed through the 50 amp main generator break-
er located on the AC main ship’s panel under the main
breaker.
See the previous illustration and the generator
section for further information.
Before activating the generator AC breaker it is recom-
mended to make sure all the equipment breakers are “off.”
Next, make sure the generator is started. Slide Bar B up
and activate the paralllel (transfer) breaker. Move Bar A
up and activate the generator breaker. The panel should
now be controlled by the generator. Switch on sub panel
breakers as needed.
LINE VOLTAGE/CURRENT METERS
After the shore power 30 amp main breaker or genera-
tor 50 amp breaker is activated line voltage will display
on the line voltage meter of the main panel. As Leg A
and Leg B volt equipment breakers are activated the load
current meter (extreme right side of panel) will show an
amperage draw. Normally the amperage will ascend as
more equipment breakers are activated and will descend
as equipment breakers are deactivated.
After the 30 amp main panel breaker or generator breaker
has been activated no voltage will appear on the 120 line
voltage meter at the extreme left side of the main control
panel with the 120 shore power switch in the “off or cen-
ter” position. This is normal. See the illustration.
The 120 volt shore power switch is located between the
line voltage and load current meters. See the illustration.
As stated above with the shore power switch in the “cen-
ter” position it is off. When the shore power switch is
moved to the left the line voltage meter will display up
to 120 volts available at leg A. As equipment breakers are
activated the load current (amperage) meter will ascend
and descend as equipment breakers are deactivated.
When the shore power switch is moved to the right the
line voltage meter will display up to 120 volts available at
leg B. As equipment breakers are activated the load cur-
rent (amperage) meter will ascend and descend as equip-
ment breakers are deactivated.
As a general note on equipment breakers when leaving
the boat it is recommended that most breakers be turned
off.
It may be necessary to leave the battery charger on dur-
ing extended periods and the salon refrigerator. Since the
refrigerator is dual voltage (12 and 120) make sure the DC
refrigerator breaker is activated and the AC refrigerator
breaker is deactivated upon leaving the vessel.
