Why does the cross-section of the neutral conductor not have to be thicker than that of the outer conductor - after all, N carries all 3 currents? Realize that the three-phase system is (almost) everywhere. Determine the current on N with a phasor diagram.

03:21 Cross section of the N.
03:35 Triple the cross-section?
05:14 omit N? Neutral point shift
06:00 Cross section of N as for L?
