120/240 VOLT MAIN YACHT CONTROL PANEL
REVERSE POLARITY INDICATOR
Before activating the 60 amp main breaker visually check
for a green light at the reverse polarity indicator. The
green light indicates there is no reverse polarity. There
are 3 reverse polarity indicators identifi ed on the illustra-
tion by the numeral 1. If the red light appears on the
revese polarity indicator a hot wire and ground are prob-
ably reversed somewhere in the circuit from the dock to
the main panel. In either case do not activate the main
60 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.
60 AMP MAIN BREAKER
This main breaker controls power to the 120 and 240
volt sections of the panel and eventually delivers electric-
ity 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 to the "off " position. This prevents any exces-
sive equipment motor draws and may eliminate any sys-
tem 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 the sub breakers as
needed.
60 AMP AC GENERATOR BREAKER
When the yacht is under generator power at sea AC elec-
tricity is distributed through the 60 amp main generator
breaker located on the AC main ship's panel beside the
main breaker. See the previous illustration and the genera-
tor 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 60 amp breaker
arm will clear when activated. Push the single throw arm
up to energize generator AC current to the sub panel
breakers. Switch on the sub panel breakers as needed.
LINE VOLTAGE/CURRENT METERS
After the shore power 60 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.
After the 60 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.
When leaving the vessel for extended periods with the dockside cord
system activated it is recommended to leave the inverter breaker on
the 120 volt side of the ship's main AC panel on along with the
refrigerator and cockpit refrigerator breakers on the sub-panel to the
right of the ship's main AC panel. This will protect the salon sub-
zero refrigerator items along with the cockpit unit.
