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 switch.
2.Select mounting location and cut opening
Select a mounting location which is protected from water on the front and back of the switch and is not in an area where flammable vapors from propane, gasoline or lead acid batteries accumulate. AC rotary switches are not ignition protected and may ignite such vapors.
Using the template provided, drill the mounting surface where the switch is to be mounted. The mounting surface maximum thickness is 0.157” (4.00mm). Do not yet fasten the switch to the mounting surface.
3.Install source 1, source 2 and output wires
Install the feed wires from AC Shore Power and AC Generator. Install the output wires. Refer to the wire sizing chart to select the minimum wire size. Connect the black AC hot, white AC neutral and green AC safety ground as shown in the illustration. To avoid excess wire temperatures when cooling may be limited, we recommend using at least 12 gauge wire for 30A and 8 gauge wire for 50A.
Do not confuse the neutral current carrying wires (sometimes called ground) with the green normally
A double pole circuit breaker must be installed within 10 feet of the shore power inlet, ahead of this switch. The measurement is made along the conductors.
WARNING 
These instructions are intended to provide assistance with the installation of this product, and are not a substitute for a more comprehensive understanding of electrical systems. We strongly recommend that a competent electrical professional perform the installation of this product.
If either the switch front or back is to be exposed to water it must be protected with a waterproof shield.
The switch must not be installed in explosive environments such as gasoline engine rooms or battery compartments as the switches are not ignition proof.
The vessel’s shore power cord must be disconnected form shoreside power before installing this electrical switch.
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 switch is installed.
Verify that no other AC or DC source is connected to the vessel’s wiring before the switch is installed.

The switch provides switching, but does not provide circuit protection. It is not a substitute for a main circuit breaker.
Wire sizing chart
Use the wire sizing chart below to determine the proper branch and feed circuit wire sizes.
Allowable Amperage of Conductors
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.
4. Testing
It is very important that the wiring be connected according to the diagram. The line and neutral from each source must be paired together and not connected such that the switch selects line from one source and neutral from another. Verify the connections and see that each connection is securely tightened, including the terminals for the jumpers installed on the switch where no wires are attached.
It is possible to verify the connections using an ohmmeter before power is applied. These procedures take a little time, but are recommended, especially if some elements of a previous installation might not have been properly labeled or followed the expected color codes.
