Blue Sea Systems 8380 DC Main + 22 Positions, White Toggle - Manual

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
If this panel is to serve as your main shore power disconnect circuit
breaker, select a location which is not more then 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 then 10 feet additional fuses or circuit breakers must be
installed within 10 feet of the shore power inlet.
Select a mounting location which is protected from water on the panel
front and back and is not in an area where fl ammable vapors from
propane, gas 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 cutout in the mounting
surface where the distribution panel is to be mounted. Do not yet fasten
the panel to the mounting surface.
3. 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, which
ever 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

WARNING
@
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 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 main positive connection must be disconnected at the battery post to
avoid the possibility of a short circuit during the installation of this
distribution panel.

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.
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.
4. 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.
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.
Next, connect a minimum 16 AWG red wire from the screw on the side of
the shunt positive terminal to the meter positive terminal and connect a
black or yellow wire from the shunt negative terminal to the meter
negative terminal. There should be a 1 ampere fuse in both sense wires
near the shunt terminal. Be certain that on all 4 shunt connections the
wire ring terminals sit directly on the brass blocks of the shunt without any
washers in between.
Connect a negative return wire from both negative buses on the panel
to DC negative.
5. Install battery bank voltage monitor wires
The panel is supplied with a digital meter and switch to monitor the
