How we calculate the guage of power cable on different load?

the cable manufacturer should have a table of how much current can be used for the different diameter cables. Or the electrical engineering in pakistan should be pointing you to such publications. rw

first you figure out how much voltage drop you can live with, and how much heat the cable can dissipate without becoming a problem or failing

Then you choose a wire of suitable or lower resistance.

If there are legal requirements they must be considered also.
