240v Wiring ?

[Keith Foor]

I think were getting into symantics (which is a fun hobby of mine as thats what words are for )

Polarity can only discribe a system of two opposits as wrek wrek says so we have to call three phase somthing else, maybe "phase order" is a better term for 3 phase.

This is intended to be light hearted as aposed to be pernickity

Yes, I believe that you put it to words better than I.

That isn't technically correct. With 3 phase having the phases out of order will reverse the motor so it does matter. Of course the only thing that will happen is it will turn the opposite direction, and fixing it is swapping two or the phases.

Correct the the legs change polarity 60 times per second in the US, if one had a device that was effected by polarity that operated at a frequency higher then the line I should imagine that problems would occur. A simple induction motor is not such a device.
