What is an "XY" rated safety capacitor, exactly?
Only Y class capacitors are sufficient for use in ''line-to-ground'' applications. Because of the stricter safety ratings, it is acceptable to use Y-rated capacitors in place of X-rated capacitors, but not vise versa. Capacitors explicitly rated for both are not uncommon, and there is nothing preventing a capacitor from being both classes at once.
A few safety measures that could save your life
The capacitor manufacturer cannot predict every possible stress which a power capacitor may be subjected to, and which has to be taken into account in a proper design. This means that the user bears crucial co-responsibility. For this reason, safety and quality should be the main priorities when selecting a capacitor.
