how to calculate the size of cable for 100 kva load,?can
somebody tell me with a formula

Answer Posted / sridhar nayak

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

Is This Answer Correct ?    16 Yes 15 No
