cable size is calculated depending up on load ..for example
1 kw load takes 1.8 amps current..if the load is 5kw..than
9amp is the current for amp current the selection cable size
can be opted on the basis of manufature detial like
havells,polly cab..have the range of cable for certain
amount of current we have to selected the cable size on the
basis of manufacture range sheet
