Blue Sea Systems PN 8408 Manual Do Utilizador

  The panel is supplied with a digital meter and switch to monitor the    
  voltage of three separate sources, usually the batteries. Connect a    
 minimum 16 AWG red wire from each source to be monitored to each of
  the corresponding input wires of the switch. There should be a 1 ampere  
  fuse in each positive wire near each source.

 

  Determine the proper wire size for each branch circuit using the  

 

  guidelines in step 4. Verify that the standard 15 amp circuit breakers  
  installed in the panel are large enough for each branch circuit. Remove  
  and replace with a higher amperage any that are undersized. Connect  
  the positive (red) branch circuit wires to the load terminals of each circuit  
  breaker. Connect each negative (black) branch circuit wire to the DC  
 Negative Bus. DO NOT CONFUSE THE DC NEGATIVE BUS WITH THE
 DC GROUNDING BUS.

5. Optional—install grounding system wire

  The grounding wire (bare, green or green with yellow stripe and normally  

  non-current carrying) should not be confused with the negative ground  

  wire (black or yellow and normally current carrying). 
  In Boatowner’s Illustrated Electrical Handbook, Charlie Wing identifies

  three purposes of DC Grounding:

  1.  Holding conductive housings of low voltage (under 50 volts) DC   
   

devices at ground potential by providing a low resistance return   

   

path for currents accidentally contacting the device cases. 

  2.  Providing a low resistance return path for electrical current,  

 

   

preventing stray currents that may cause corrosion.

  3.  Grounding metal electrical cases to prevent emission from inside  
   

or absorption from outside of radio frequency noise (RFI).

  ABYC requires that grounding wires be sized no smaller than one wire  
  size under that required for current carrying conductors supplying the  
  device to which the grounding wire is connected.

 

Connect the yellow negative wire to the panel negative bus.  Do not  

 

To activate the label lights by the boat’s battery switch, connect the red  

 

positive wire to the DC positive bus.  Do not confuse with the AC 

 

To activate the label lights by an independent switch or breaker,  

 

 

connect the red positive wire to the load side of a DC switch or breaker.

 

This panel is supplied with LEDs pre-installed in all optional branch   

 

positions. For future expansion of the panel remove the positive leg of  

 

the LED from the negative bus and connect it to the load side of the  

 

corresponding branch circuit breaker.

This Blue Sea Systems electrical distribution panel is furnished with 15A 
circuit breakers for DC branch circuits. These ratings will satisfy the vast 
majority of marine circit protection situations. As shown in the Wire Sizing 
Chart, even 16 AWG wire, which is the minimum wire size recommended by
ABYC, has an allowable amperage greater than 20A.

 

  Determine the proper wire size for each branch circuit using the chart  
  below. 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.

  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 non-current carrying wires (sometimes  
  called grounding). These two wires must be connected only at the source  
  of power, nowhere else.

Use the wire sizing chart below to determine the proper branch 

and feed circuit wire sizes.

  Install the feed wires from the shore power inlet or other AC source,   
  referring 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.

  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, an  

 

  additional fuses or circuit breakers must be installed within 10 feet of the  
  shore power inlet. The measurement is made along the conductors.

  This Panel is supplied with LEDs pre-installed in all optional branch   
  positions. For future expansion of the panel remove the hot leg of the  
 LED from the AC Neutral Bus and connect it to the Load side of the
  branch circuit breaker.

This Blue Sea Systems electrical distribution panel is furnished with 15A or 
8A circuit breakers for AC branch circuits. 15A circuit breakers are used in 
all 120V panels and 8A circuit breakers are used in all 230V panels. These 
ratings will satisfy the vast majority of marine circuit protection situations.
