You want to see harmonics take a look at variable frequency drives...
Ive seen them 'melt' neutrals. The newer ones are alot better but those old SCR chopping VFD's were a nightmare. Another big contributer to harmonics are PC's yup good old computers. Get enough of them on one phase and you will see why they design systems with 200% neutrals.
