Please tell where did you use the cable. i.e. for control
and power purpose.
For Power cable :-
LT purpose :- 1 sqmm cu cable :- it will take 4 amp current
a/c to formula you can calculate the cable size.
LT purpose :- 1 sqmm al cable :- it will take 1.5 amp
current a/c to formula you can calculate the cable size.
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.
