How do you calculate the current carrying capacity of copper and Aluminium cable?

Cable Capacity

For Cu Wire Current Capacity (Up to 30 Sq.mm) = 6X Size of Wire in Sq.mm. Ex.
For Cable Current Capacity = 4X Size of Cable in Sq.mm, Ex. For 2.5 Sq.mm = 4×2.5 = 9 Amp.
Nomenclature for cable Rating = Uo/U.
where Uo = Phase-Ground Voltage, U = Phase-Phase Voltage, Um = Highest Permissible Voltage.

What is diameter of 2.5 sq mm cable?

Convert wire area from square mm to diameter mm.

Wire
mm2	mm
1.5	1.4
2	1.5
2.5	1.8

How do you calculate the current capacity of Aluminium cable?

Aluminium current-carrying is equal to 0.8 times of the total volume of the aluminium (length*breath*thickness). Let’s have a simple example of 4 sqmm bus bar. Apply our equation, Current carry capacity of 35 sqmm bar= 0.8* 35 = 28 Amps.
