Derating Factors


Derating Factors for Bundling of Single Core Cables per JASO D609

As the number of cables bundled together increases, the current capacity of each cable in the bundle decreases as per the following chart.

Cable Bundle Qty = Derating Factor for 4 B&S

  • 1 x Cable = 100% capacity (135amp)

  • 2 x Cables = 80% capacity (108amp)

  • 3 x Cables = 70% capacity (95amp)

  • 4 x Cables = 60% capacity (81amp)

  • 5 x Cables = 55% capacity (74amp)

  • 6 x Cables = 50% capacity (68amp)

  • 7 x Cables = 50% capacity (68amp)

     

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 4 B&S 

  • 30°C = 100% capacity (135amp)

  • 40°C = 90% capacity (122amp)

  • 50°C = 76% capacity (103amp)

  • 60°C = 60% capacity (81amp)

  • 70°C = 45% capacity (61amp)

Voltage Drop for 4B&S Cable: 

To calculate the voltage drop of 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 4 B&S:

How much voltage drop over 10m of 4 B&S with a current draw of 135A?

 

  • 10m x 135A x 0.017 = 22.95

 

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

 

  • 22.953/20.26 = 1.133V

 

You will have a drop of approximatley 1.13 Volts over the 10m length
