Size depends on two things
1. Current rating normally load current should be 70-80% of
cable's minimum capacity.
2. Voltage drop should be within limit i.e. for lighting 3%
and for motor during starting within 10%.

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
