I want formula to calculate cable size as per load given in
kw & amp.I searched many sites but didn't right answer.Plz
reply me asap.

Answer Posted / er.nitesh

You want the appropriate cable size then just apply the
frml P=V*I*Cos#
Where voltage = 0.240
Load is given and cos# lie between 0.8 to 0.9
you can easily get the ampere rating and choosecable size.
