Dave, X caps are used line-to-line.
Y caps are used line-to-ground. I remember this by thinking of the "X" crossing line-to-line. A "Y" looks like it's pointing down or heading towards ground; that's how I remember a Y cap is from line-to-ground.

It seems that many use the term Y to refer to caps from line-to-line and the term X to refer to caps from line-to-ground (or is it the other way 'round). While researching caps I found that X basically designates a cap which is designed to never fail shorted. This would be the one to use for line-to-ground applications. And that Y refers to a cap which can fail shorted. This would be acceptable for line-to-line. Thanks to all for the input on my hipot question. That cleared things up for me.
