Answer / soumendasbiswas
Fist Calculate the Full load current..then assume some
derating factor...nd evaluate that current..then check that
current with ny reputed cable makers manual(Havells,Pollycab)
to get the actual cable size

Answer / robins
Cable calculation is based on the following factors:
1.Total current based on the peak load(total connected .
2.Cable length
3.Type of cable using(get from manual of cable manufactures)
4.Ambient temperature(normally 28 degrees)

Answer / azhar
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
