Answer / naresh kumar dhal
100kva load has total current of-139 amps.
if we consider derating factor=0.8
Then total current=139/.8=173 amps
For 173 amps we can use 120 sqmm cable.
Its current capacity=1.5*120=180amps

P=1.732VI
u calculate i,take voltage 415V for three phase LT
if i=x,than cable size x=20 or 30
cable sizes are-35,75,95,120,150,185,240,300,400sqmm
it apllicable for alluminium cable only

Answer / manoj patel
From KVA , You get value of Amp.
By using standard cable catloge (size versis capacity)
you can find cable size.
That is only way to find cable size.From my point of
view there is no standard formula for that.

Answer / venkatesh
1kva=1.7amps
100kva=170amps
firstfall we are find out cable item aluminium or copper
aluminium gives 1sqmm=1amp sand copper gives 1sqmm=2amps
but we can use more than 2amps beacuse cable long time will
not come.we have to select aluminium cable for 185sqmm
beacuse total load is 170amps 185sqmm is enoff
