Hank, valid point if it is a four wire 240 supply. Maybe it's just semantics, but I would not call what you describe as reversed polarity. Of course with ac there is no polarity as such. Disregarding three phase rotation orders etc as out of scope.
I assumed, probably shouldn't have, that reversed polarity meant a hot and neutral swapped. No that is not reversed polarity, as you said, no polarity in AC.
Ever notice that many people describe an electrical problem as a short when actually it's a loose, corroded or intermittent connection. Shorts, blow fuses, trip breakers or start fires.
In DC people also say that current flows from positive to ground or negative. Electrons are negatively charged and flow from negative to positive.
I don't sweat minor details like that as long as everyone understands the basics.
