Default Re: Beware!

I would be inclined to wire a low value safety resistor in series with these caps now. If for instance the cap failed and started passing any large amounts of current but not enough to blow the fuse it "should" take out the resistor!
I am not too sure of the value to use but I would go for 10 ohm at 0.1w fusible, I know some of the suppression type X rated caps incorporate 150 ohm resistors and perhaps this is what we should be using as mains filter types!
