It'll still turn the same direction.

Don't feed the trolls.


Not neccessarily a troll. This is a common problem with three phase
supplies.


Nor have I ever seen a three phase motor suddenly up and
change rotational directions without some kind of major
problem form the power company or someone rewiring
incorrectly on premises...

When you drop a phase on a 3-phase motor it doesn't
put out its rated HP and won't handle a loaded condition...
It doesn't all of the sudden start rotating backwards...- Hide quoted text -

It's avery common problem if someone has been replacing cables on the
power supply system and hasn't checkedto phase rotation.
