The Purpose of a Panel
There are six purposes of a marine electrical panel:
• Power distribution
• Circuit (wire) protection
• Circuit ON/OFF switching
• Reverse Polarity Indication
• Metering of voltage and amperage (In panels with meters)
• Condition Indication (circuit energized)
Applicable Standards
• 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.

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 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 vessel’s wiring before
the panel is installed.
Installation
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 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.
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 cut out in the mounting
surface where the distribution panel is to be mounted. Do not yet
fasten the panel to the mounting surface.
3. Install feed and output wires
Install the feed wires from the AC source. Install the output wires. Refer
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.

Wire sizing chart
Use the wire sizing chart below to determine the minimum branch and feed
circuit wire sizes.
Note: This chart assumes wire with 105° C insulation rating
and no more than 2 conductors are bundled.
Not suitable for sizing flexible shore power cords.
Do not confuse the white AC neutral current carrying wires (sometimes
called ground) with the green safety ground normally non-current
carrying wires (sometimes called grounding). These two wires must be
connected only at the source of power, nowhere else.
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.
