    Three phase/120 moves more power for less copper andless
    loss than 2phase 90.

    Or so the textbooks demonstrated in school.   That was
    40 odd years ago:  the texts (and maths details) are long
    since lost.  The prevalence of the three phase/120 system
    demonstrates its benefits...

    I dunno if current texts go into the benefits...
