Dear all.
I am to install a three phase system for load consisting mainly single phase. I have divided the single phase loads in to three and fed each group with one hot from the three hots. But each group use the same return line the neutral, the problem is, shouldn't I tripple the thickness of the neutral because it cary all the phases currents? To worsening my problem standard cable neutral thickness is even smaller than the phase. I have attached sketch of this
