Answer Posted / dipesh kumar
The current carrying capacity of a cable is called
Ampacity. For the porpose of the above calculation there
are some concepts that must be taken in consideration .
like Dia,Insulation material and thickness,type of conductor
(Copper/Aluminium),Resistivity and the working conditions.
For BETTER CONCEPT I advice the readors to please refer
the "Recommended Cable Sizes and their load capacity as per
IS:13947 & IEC 60947". Below given table can help you.
