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