Answer Posted / raj
If you use all 3ph ( R,Y,B Core of Cable ) for single phase
load then only unbalanced current will flow through neutral
(1/2 Conductor ) but we must try to balance current in all
R,Y,B Phases.If you have to use only one single phase
circuit then use R+Y for Phase and B+Black for neutral (
Use twin Core to get more rating outout ).
