• Derating Factors for Ambient Temperatures °C per JASO D609

  
  

  As the ambient temperature increases, the current capacity of the cable decreases as per the following chart.

  
  

  Ambiebt Temperature °C = Derating Factor for Twin 4 B&S 

  
  

  • 30°C = 100% capacity (108amp)

  • 40°C = 90% capacity (97.20amp)

  • 50°C = 76% capacity (82.08amp)

  • 60°C = 60% capacity (64.80amp)

  • 70°C = 45% capacity (48.60amp)

  Voltage Drop for Twin 4 B&S Cable: 

  To calculate the voltage drop of Twin 4 B&S copper cable, use the following formula:

   

  Voltage Drop = Length x Current x 0.017
                                        Area (20.26)

   

  Length = Total length of cable in metres.

  Current = Current draw (amps) through the cable.

  Area = Cross sectional area of the copper (in this case 20.26mm²)

   

  Notes:

  • Formula only applies to copper at 25°C, voltage drop increases with both ambient and cable temperature, at approx 0.4% per °C.

  • 0.017 - This multiplication factor only applies to copper

   

  Example for Twin 4 B&S:

  How much voltage drop over 10m of Twin 4 B&S with a current draw of 108A?

   

  • 10m x 108A x 0.017 = 18.36

   

  Divide this by 20.26 (cross sectional area of 4 B&S - mm²)

   

  • 18.36/20.26 = 0.9062V

   

  You will have a drop of approximatley 0.91 Volts over the 10m length
