Hi Chris, the difficulty of using a Y class across the mains is that they are not easily available in typical X cap values, at least not in reasonable sizes.
In terms of voltage rating of the X Cap when a series resistor is fitted the resistor is ignored (but it may be helpful in suppressing some level of noise
