TYPICAL AC MAIN YACHT CONTROL PANEL
REVERSE POLARITY INDICATOR
Before activating the 50 amp main breaker visually
check for a green light at the reverse polarity indicator.
Th
e green light indicates there is no reverse polarity. If
the red light appears on the revese polarity indicator a
hot wire and ground are probably reversed somewhere
in the circuit from the dock to the main panel. Th
e ELCI
breaker will “trip” if a reversed polarity situation devel-
ops. Also, it is possible that the main 50 amp shore pow-
er inlet breaker will “trip”.
In all cases do not activate the main 50 amp breaker.
Take immediate corrective action to fi nd the cause of
the reverse polarity situation. At this point, disconnect
the shorepower cord from the marina power center and
call for professional assistance.
50 AMP MAIN BREAKER
As previously stated the AC panel mounted single
throw, triple pole main breaker controls power to the
120 and 240 volt sections of the panel and eventually de-
livers electricity through a system of sub breakers to the
entire yacht. Before you energize the breaker it is always
a good idea to check all the legs on both the 120 volt and
240 volt side for breakers that are in the “on” position.
Turn any breakers found “on” to the “off ” position. Th
is
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 up. AC electricity now is distributed to both
the 120 and 240 volt legs of the panel. Turn on sub
breakers as needed always being conscious of the load
current meters..
50 AMP AC GENERATOR BREAKER
When the yacht is under generator power at sea AC
electricity is distributed through the main generator
breaker located on the AC main ship’s panel beside the
main breaker.
See the previous illustration and the gen-
erator section for further information.
Before activating the generator AC breaker it is recom-
mended to make sure all the equipment breakers are
“off .” Slide the bar to the left so the generator breaker
arm will clear when activated. Push the single throw
arm up to energize generator AC current to the sub pan-
el breakers. Switch on the sub panel breakers as needed.
LINE VOLTAGE/CURRENT METERS
Aft er the shore power 50 amp main breaker or genera-
tor breaker is activated line voltage up to 240 volts will
display on the 240 volt (right side) of the main panel. As
sub panel 240 volt equipment breakers are activated the
load current meter (extreme right side of 240 volt 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.
Aft er the 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. Th
is is normal. See the illustration.
Th
e 120 volt shore power switch is located between the
line voltage and load current meters. See the illustra-
tion.
As stated above with the shore power switch in the “cen-
ter” position it is off . When the shore power switch is
moved to Line 1 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 Line 2 the
line voltage meter will display up to 120 volts available
at leg B. 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 in the center position
240 volts will show in the right line voltage panel.
It may be necessary to leave the battery charger on dur-
ing extended periods. Since the cabin 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.
