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.
Best regards,
Dave

I'm looking for a source for the manual and cables other than AR (too
