Most know about motor rotation but he was
talking about delta versus Y. This can be quite
different.

I can't think of a specific incident like
that, but I do know
that our University uses a non-standard order of phases, and
that all the electrical contractors who come on site get a
lecture about it, for obvious reasons!
What's a "standard order of phases"? I know if you inadvertently
swap any two you potentially end up spinning the other way. For
some things this matters and for other it doesn't.
I can only assume I'm missing something obvious ...
