    Can a relay rated for 110V 15 Amps be used safely on a 220V 7.5 Amp device?

    Specifically, I want to use a "X-10 appliance module" to switch a 220V AC
    unit (7.5 amp) in my home.
    I have found both 110 and 220 volt appliance modules, but the 220v ones have
    a really loud relay click
    that will be disturbing when it is switching on and off the bedroom AC/heat.
    The 110v unit is 80% quieter.

    | What will be even louder than the click will be the fire engines'
    | sirens.

    Even louder will be your home insurance company denying your claim.
