Answer Posted / at
3 core cables are used where ever the system is ungrounded.
3.5 core cables are used where the major load in an
industry / plant etc. is three phase but also has single
phase loads or loads that can cause a little unbalancing
and thus the nutral might carry some current but not always
and not as much as the line current. Therefore a smaller
cross section of nutral can solve the purpose as current
through nutral will be very small as compared to the rated
current of the cable.
4 core cables are used in systems where all loads are
single phase or majority loads are single phase. so there
are chances of high degree of unbalancing. and nutral has
to carry a larger amount of current.Therefore half cross
section of nutral may not solve the purpose and we opt for
4 core cables. This arrangement is used for small cross
section cables used in homes and industries. for lighting
and other small applications.
