a/c to formula you can calculate the cable size.

LT purpose :- 1 sqmm al cable :- it will take 1.5 amp

HT pupose :- we can go a/c the LT purpose cables but there
is voltage drop plays very crucial role, first calculate
the current value then calculate the voltage drop after
doing these exercises you can select the cables.
