Installation Set Up  
DC Installation  
1. Disconnect all AC and DC power  
1. Select positive feed wire and negative return  
Determine the positive feed (red) and negative return (black or yellow)  
wire size by calculating the total amperage of the circuits that will be  
routed through the panel. Blue Sea Systems’ electrical panels are rated  
at 100 amp total capacity. The positive feed wire must be sized for 3%  
voltage drop at the 100 amp panel rating or the maximum amperage  
that will be routed through the panel in any particular installation,  
whichever is less. It is recommended that the positive feed wire be sized  
for the full panel capacity, which, in most cases, will require at least 2  
AWG wire, assuming a 10 foot wire run between the panel and the  
batteries in 12 volt systems. Refer to the Wire Sizing Chart for other  
situations. In the case of panels with two or more columns of breakers,  
jumpers from positive bus to positive bus and from negative bus to  
negative bus should be the same size as the positive feed and the  
negative return wires.  
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  
If this panel is to serve as your main shore power disconnect circuit  
breaker, select 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. If  
it is more than 10 feet, additional fuses or circuit breakers must be  
installed within 10 feet of the shore power inlet.  
Remember that the length of the circuit is the total of the positive wire  
from the power source and the negative wire back to the DC Negative  
Bus. Be certain that there is a fuse or circuit breaker of the correct size  
protecting the positive feed wire.  
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.  
2.Install shunt, positive feed wire and negative return  
The panel is supplied with an external shunt ammeter that must be  
connected in the positive feed line to the panel. The shunt may be  
mounted at any point in the feed line, but mounting it close to the panel  
will keep the sense wires that run to the meter short, minimizing  
voltage loss and interference, creating the most accurate meter  
reading.  
Using the panel template provided, make a cutout in the mounting  
surface where the distribution panel is to be mounted. Do not yet fasten  
the panel to the mounting surface.  
Connect the positive feed wire from the positive source to either of the  
2 large bolt terminals on the shunt top. This is now the shunt positive  
terminal. Connect two additional lengths of feed wire from the remaining  
shunt terminal, now the negative terminal, to both panel positive buses.

2. Install feed circuit wires  
Reference  
Applicable Standards  
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.  
• American Boat and Yacht Council (ABYC) Standards and Recommended  
Practices for Small Craft sections: E-1, E-3, E-9.  
• United States Coast Guard 33 CFR Sub Part 1, Electrical Systems  
Useful Reference Books  
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,  
additional fuses or circuit breakers must be installed within 10 feet of the  
shore power inlet. The measurement is made along the conductors.

3. Optional Branch LEDs  
This panel is supplied with LEDs pre-installed in all optional branch  
positions. For future expansion of the panel remove the AC hot leg of the  
LED from the AC neutral bus and connect it to the load side of the  
corresponding branch circuit breaker.  
Note  
This Blue Sea Systems electrical distribution panel is furnished with 15A or  
8A circuit breakers for AC branch circuits. 15A circuit breakers are used in  
all 120V panels and 8A circuit breakers are used in all 230V panels. These  
ratings will satisfy the vast majority of marine circuit protection situations.

Panel Mounting and Testing  
1. Apply branch circuit labels and mount panel  
Apply a label for each circuit from the label set provided. If the  
appropriate label is not included, extended label sets are available  
through retail suppliers, and over 500 individual labels are available  
order stock or custom labels for specific applications.  
Fasten the panel to the mounting surface using the screws provided.  
2. Testing  
]
Reconnect the main positive cable to the battery terminals and turn  
the main switch on to supply power to the panel. Turn on all branch  
circuits and test the voltage at the panel. Compare this voltage to  
the battery terminal voltage to determine that the voltage drop is  
within 3%. With all branch circuits still on, test the voltage at one  
device on each circuit to determine that there is a 3% or 10% drop  
as is appropriate.  
]
Connect the shore power cable to the boat AC power inlet. Do not  
connect the shore power cable to the shore power pedestal. Instead  
run the shore power cable such that the shore power plug is next to  
the AC panel. With an Ohmmeter verify that the pins of the shore  
power plug are connected to the appropriate terminals of the panel.  
Refer to ABYC E-11 Figure 13 or 14 or NEC / NEMA documents for  
the standard pin arrangements for your plug.  
]
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:  
PN 8095 / PN 3095—120 Volt AC  
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.  
PN 8195 / PN 3195—230 Volt AC  
a. 230 volts between hot and neutral  
(nominal, this may vary depending on source voltage)  
b. 230 volts between hot and ground.  
c. 0 volts between neutral and ground.  
]
Turn on each branch circuit to verify power to each circuit.
