Boss, for AL cable 1sqmm take nearly 1-1.5A current, if the conductor size goes on increases to a large extent then take it has 1A. But there's no large variations from meter to meter... Ex: 5m cable and 15m cable there is no loading current variation, it varying in long cables due to voltage drop..

why we are used D.c. voltage in L.T.side or controling side.we can use UPS also ,in place d.c. voltage
