  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 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.

  

Any Blue Sea Systems product with which a customer is not satisfi ed 
may be returned for a refund or replacement at any time. 

 

 

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 fl ammable vapors 
from propane, gas or lead acid batteries accumulate. AC rotary 
switches 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.

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 wires 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 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 minimum branch and

feed circuit wire sizes.

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.
