Answer Posted / p.k.chadhar
3 core cable can be used for three phase power supply
without earthing
3&1/2 cable can be used for three phase power supply with
earthing because 1/2 core is mostly used for earthing or
gounding
4 core cable can also be used for three phase power supply
with earthing this cable can also be used for control supply
it depends on size of the cable if it is 1.5 mmsq.then
control ,if size is more can be used for power connection.
