Answer / benchmark pakistan

mostly 1mm cable can handle 2amps current, by calculating
load current from given Kw we can easly find suitable cable
for load

Answer / nishant

Its depends on the voltage drop by current calculated from
KW rating. In india generally 3% voltage drop is considered
pumps/motors. It is basically different for different
equipment. It also depends on the cable length. If cable
length is more then voltage will be high so size will be high.

Answer / amol tajane

it simple if load is given in kw just calculate the
current.by refering any cable manafacturer cable catlouge
ampere matching cable can be selected

Answer / md. al-amin sarker

as far i know,
for copper cable,
rm or sqmm = KW * 0.7
kw = 3 phase or single phase load.
the cable size can vary with temperature. because resistance
vary with temperature.

Answer / karteek.k

it entirely depends upon voltage drop across cable

v=I*R, i.e V is directly proportional to I. now P=V*I. so V=P/I. thus v is inversely proportional to I. so what is the correct one? If both are correct than for which kind of condition this 2 differ
