Answer Posted / mukesh kumar
3 core is used for 3-ph loads/systems which do not require
neutral e.g. motors. 3.5/4 core is used wherever 1-ph
supply is also required (tapped between 1ph-N) in addition
to 3 phase supply. 4 core used for smaller cables usually
upto 16 sqmm where neutral core is of same size as phase
cores while 3.5 core is used for higher sizes where neutral
core is half the size of phase cores.
