    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.

    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.
