Line voltage

[Murray]

I never understood where 117 came from, or 110. In school, they tried to
convince us that 120 'naturally' comes from line-to-ground in a 208 3-phase
system, the God-given 'natural' source of power. I was a little hesitant,
but I did understand the trig relationship that explained it. (120 degrees
phase difference between 3-phase 'lines') We don't have 3-phase in our
residential neighborhood.
