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 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 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.
3.Install branch circuit wires
Determine the proper wire size for each branch circuit using the wire sizing chart. 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.
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 vessels’ wiring before the panel is installed.

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
Use the wire sizing chart below to determine the proper branch
and feed circuit wire sizes.
Allowable Amperage of ConductorsNote: | This chart assumes wire with 105°C insulation rating |
| and no more then 2 conductors are bundled. |
| Not suitable for sizing flexible shore power cords. |
