1.
Disconnect all AC and DC power
Disconnect all AC power originating on or off the vessel. This includes
inverters, generators, shore power attachments and any other device
capable of supplying AC power to the ship's circuits.
Disconnect the main positive DC cable from all batteries to eliminate
the possibility of a short circuit and to disable the inverter while
installing the distribution panel.
2.
Select mounting location and cut opening
Select a mounting location which is protected from water on the panel
front and back and is not in an area where flammable vapors from
propane, gasoline or lead acid batteries accumulate. The circuit
breakers used in marine electrical panels are not ignition protected and
may ignite such vapors.
Using the panel template provided, make a cut out in the mounting
surface where the distribution panel is to be mounted. Do not yet
fasten the panel to the mounting surface.
This panel is not intended to serve as the main AC circuit breaker
panel. A double pole circuit breaker that breaks both the AC hot and
neutral legs (such as Blue Sea Systems' PN 8029) must be installed in
a location which is not more than 10 feet from the shore power inlet or
the electrical attachment point of a permanently installed shore power
cord as measured along the conductors of the feed wires.
3.
Install branch circuit wires
Determine the proper wire size for each branch circuit using the chart
below. Verify that the standard circuit breakers installed in the panel
are correct for each branch circuit. Remove and replace any that are
incorrectly sized. The circuit breaker must have a rating less than the
allowable amperage of the wire, yet greater than the circuit's
continuous current.
Connect each branch circuit hot (black) to the appropriate load
terminal. Connect each branch circuit neutral (white) to one of the
screws on the neutral bus. Connect each branch safety ground wire
(green) to one of the screws of the safety ground bus.
Do not confuse the neutral current carrying wires (sometimes called
ground) with the green normally non-current carrying wires (sometimes
called grounding). These two wires must be connected only at the
source of power, nowhere else.

Use the wire sizing chart below to determine the minimum branch and
feed circuit wire sizes.

]
It is not possible within the scope of these instructions to fully
acquaint the installer with all the knowledge of electrical systems
that may be necessary to correctly install this product. If the installer
is not knowledgeable in electrical systems we strongly recommend
that an electrical professional be retained to make the installation.
]
If either the panel front or back is to be exposed to water it must be
protected with a waterproof shield.
]
The panels must not be installed in explosive environments such as
gas engine rooms or battery compartments as the circuit breakers
are not ignition proof.
]
The vessel's shore power cord must be disconnected form shoreside
power before installing this electrical panel.
]
If an inverter is installed on the vessel its power leads must be
disconnected at the battery before the panel installation. Be aware
that many inverters have a "sleep mode" in which their voltage
potential may not be detectable with measuring equipment.
]
If an AC Generator is installed aboard it must be stopped and
rendered inoperable before the panel is installed.
]
Verify that no other AC source is connected to the vessels' wiring
before the panel is installed.
Guarantee
Any Blue Sea Systems product with which a customer is not satisfied
may be returned for a refund or replacement at any time.
