Voltage Drop for 0 B&S Cable: 

To calculate the voltage drop of 0 B&S copper cable, use the following formula:

Length = Total length of cable in metres.

Current = Current draw (amps) through the cable.

Area = Cross sectional area of the copper (in this case 49.00mm²)

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 0 B&S:

How much voltage drop over 10m of 0 B&S with a current draw of 246A?

• 10m x 246A x 0.017 = 41.82

Divide this by 49.00 (cross sectional area of 0 B&S - mm²)

• 41.82/49.00 = 0.8535V

You will have a drop of approximatley 0.85 Volts over the 10m length
