Answer Posted / k.prakashchandra
Neutral current is undesirable . If 3 phase appliances are predominant or single phase loads are balanced, . the neutral current will be small . Further in protection scheme, the EFR is normally set at 20 % of the rated current . Hence main neutral conductor may be of half the size of phase conductors to save money .
