Installation

4. Install feed circuit wires
Install the feed wires from the shore power inlet or other AC source,
referring to the wire sizing chart to select the correct wire size. Connect
the black AC hot, white AC neutral and green AC safety ground as
shown in the illustration.
If the feed wires are from the shore power inlet or the electrical
attachment point of a permanently installed shore power cord and the
inlet or attachment point is more than 10 feet from this panel, an
additional fuses or circuit breakers must be installed within 10 feet of
the shore power inlet. The measurement is made along the
conductors.
5. Installation of Backlight System
The backlight board is a DC device. When installing it in an AC panel
both wire leads must be connected to an appropriate DC source and
ground.
Connect the yellow negative wire to a DC ground. Connect the red
positive wire to any DC positive supply, usually a switch that controls
the vessel’s other nighttime illumination.
6. Apply branch circuit labels and mount panel
Apply a label for each of the branch circuits from the 30 basic labels
provided (not provided for PN 3029 and PN 8029). If the appropriate
label is not included, the Extended Label Set of 120 labels may be
ordered from your marine supplier (PN 8067). Individual labels are also
available from Blue Sea Systems for specific applications. Refer to the
label order form for a complete listing of individual labels.
Fasten the panel to the mounting surface using the panel mounting
screws supplied with the panel.
7. Testing
]
Connect the vessel’s shore power and verify the Reverse Polarity
light is not illuminated. If the red Reverse Polarity light is on then
either the hot and ground or the hot and neutral wires have been
crossed. Starting at the panel, trace the connections back as far
as necessary to locate the error.
]
Using a multimeter where the power source is connected to the
panel verify:
a. 120 volts between hot and neutral
(nominal, this may vary depending on source voltage)
b. 120 volts between hot and ground.
c. 0 volts between neutral and ground.
]
Turn on each branch circuit to verify power to each circuit.
8. Optional Branch LEDs
This Panel is supplied with LEDs pre-installed in all optional branch
positions. For future expansion of the panel remove the hot leg of the
LED from the AC Neutral Bus and connect it to the Load side of the
branch circuit breaker.
Note
This Blue Sea Systems electrical distribution panel is furnished with 15 amp
AC/DC circuit breakers for all branch circuits. This rating was selected to
minimize the need for removing the panel’s circuit breakers and reinstalling
different size circuit breakers. It is rare to have more than 15 amps of
current flowing in any one circuit. Therefore, 15 amp circuit breakers will
satisfy the vast majority of marine circuit protection situations.
