how calculate cable size in squre mm, when the load is
given by in kw? do u have current rating chart of elctrical
cables?
Answer Posted / sindhejs
With knowing the kW rating and voltage, the current can be
calculated as I=P/(sr(3)*V*pf). The pf can be assumed to be
as 0.8. After knowing the current, choose the 10% higher
current carrying capacity cable for the safety purpose.
current rating for differnt cables are different for same
size.Copper has higher current carrying capacity.
