Nuetral load

[hilltop]

I am looking for a graphical explination that depicts the potential load on a nuetral when there is 3 circuits run per nuetral in a 277V lighting circuit. If anyone knows of any PPT slides or a website that would be helpful i would greatly appreciate your help!

The illustration of the three phase voltage is similar to the three phase neutral current.

This isn't exactly what you're looking for, but it's a ppt about open neutrals on MWBCs.
