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 000 B&S

  • 1 x Cable = 100% capacity (335amp)

  • 2 x Cables = 80% capacity (268amp)

  • 3 x Cables = 70% capacity (235amp)

  • 4 x Cables = 60% capacity (201amp)

  • 5 x Cables = 55% capacity (184amp)

  • 6 x Cables = 50% capacity (168amp)

  • 7 x Cables = 50% capacity (168amp)


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 000 B&S 

  • 30°C = 100% capacity (335amp)

  • 40°C = 90% capacity (302amp)

  • 50°C = 76% capacity (255amp)

  • 60°C = 60% capacity (201amp)

  • 70°C = 45% capacity (151amp)

Voltage Drop for 000 B&S Cable: 

To calculate the voltage drop of 000 B&S copper cable, use the following formula:


Voltage Drop = Length x Current x 0.017
                                     Area (83.19)


Length = Total length of cable in metres.

Current = Current draw (amps) through the cable.

Area = Cross sectional area of the copper (in this case 83.19mm²)



  • 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 000 B&S:

How much voltage drop over 10m of 000 B&S with a current draw of 335A?


  • 10m x 335A x 0.017 = 56.95


Divide this by 83.19 (cross sectional area of 000 B&S - mm²)


  • 56.95/83.19 = 0.6846V


You will have a drop of approximatley 0.68 Volts over the 10m length
