Dear Sripellirajukumar
I had answered 7 Amps and mentioned the thumb rule for
copper is 2000 Amps per sqaure Inch ( not 2000 Amps per sq
mm ) > You need to read the answer carefully before
commenting . For Your info 1 sq inch = 25.4 x 25.4 = 645 sq
mm. Also copper purity / type of insulation / temperature
rise allowed / voltage drop tolerarable would be other
factors which need to be considered. For this 2000 Amps / Sq
inch has a generous margin ie it is has some safety margin .

why the starting voltage drop in a cable needs to be limited?what is percentage of the voltage drop allowed during starting?
If an electrical component has a positive temperature coefficient, how come such components have high power losses due to heat if current decreases when resistance increases? assuming power given by I^2*R whereby the Resistance is infinite.
