  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.

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.

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.

Install the feed wires from AC Shore Power and AC Generator. Install 

the output wires. Refer to the wire sizing chart to select the proper 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.

Do not confuse the neutral current carrying wires (sometimes called 

ground) with the green normally non-current carrying wires (sometimes 

called grounding). These two wires must be connected only at the 

source of power, nowhere else.

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.

The switch provides switching, but does not provide circuit protection. 

It is not a substitute for a main circuit breaker.

        Use the wire sizing chart below to determine the proper branch and

        feed circuit wire sizes.

It is very important that wiring be connected according to the diagram.  

The hot lines and neutral from each source must be identified and 

grouped together so that the switch selects all of the lines from the 

same source and does not accidentally select lines or neutrals from 

more than one source.  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.

If you are using this switch for other purposes, such as voltage tap 

selection on a transformer, please review your installation diagram and 

devise a suitable test plan to verify your connections.
