How it works Installation
Features
• Isolates Start circuit from House circuit: protects electronics from sags and
spikes caused by engine cranking
• Discharges batteries independently
• 100A Large Case Flat Rocker circuit breaker provides circuit protection and
switching for House/Main distribution
• Single Circuit ON/OFF battery switch controls engine Start circuit
• Single Circuit ON/OFF battery switch combines House and Start battery
banks for emergency starting (Emergency Cross Connect/Parallel)

] If the installer is not knowledgeable about electrical systems,
consult an electrical professional.
] If either the panel front or back is to be exposed to water it must be
protected with a waterproof shield.
] 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.

Engine Starting Standard
Blue Sea Systems’ battery switches, in addition to being tested to UL
1107, are also tested to the Engine Starting Standard by a United States
Coast Guard certified Nationally Recognized Testing Laboratory. The
Standard rates battery switches based on testing under very difficult
starting conditions. For information on the Engine Starting Standard,
visit Blue Sea Systems at www.bluesea.com.
DC Battery Switch Panel PN 8080 provides an electrical system in which
the main House circuit and the engine Start circuit are isolated from each
other. Battery isolation protects the Start battery from being discharged from
the many House loads like refrigerators, stereos, and lights, preserving it for
starting the engine. Battery isolation also protects sensitive electronics from
voltage spikes and sags that may occur during engine starting.
Battery switch operation is simplified because the House circuit breaker
and two battery switches are ON/OFF. The engine and house switches are
turned ON when the boat is boarded, and OFF when the boat is not in use.
In an emergency requiring that both battery banks are combined—e.g.,
a discharged start battery—the operator switches the Emergency Cross
Connect / Parallel switch to the ON position; this combines both Engine and
House battery banks.
Charging of two battery banks can be automated by adding an Automatic
Charge Relay (PN 7600 or PN 9112) to the system. This combination
creates a complete battery management system of isolated battery circuits,
emergency combine function, and automated charge management.
1. Disconnect all DC power
To eliminate the possibility of a short circuit while installing the panel,
disconnect the main positive cable from all batteries.
2. Select mounting location and cut opening
Select a mounting location that is protected from water on the panel front
and back.
Using the panel template provided, make a cut out in the mounting
surface where the panel is to be mounted. Do not fasten the panel to the
mounting surface.
3. Electrical Connections
Battery cable terminals must be attached under battery switch stud nut
and lock washer. The electrical connection illustration is general in
nature and is not meant to be a guide for the wiring of any specific
vessel. There is a wide range of wiring configurations possible. Consult
your marine electrical professional for the wiring system applicable to
your boat.
Make appropriate adjustments to the wiring diagram to suit your specific
installation and equipment. Fusing may be appropriate in several of the
lines depending on the proximity of components, conductor sheathing,
and the conductivity of the surrounding structure. Consult the Wire
Sizing Chart to determine the appropriate wire sizes.
4. Apply Labels and Mount Panel
Apply a label to each of the circuits from the label sheet provided. Use
the panel mounting screws supplied with the panel to secure the panel
to the mounting surface. Additional labels are available from
Blue Sea Systems.
