Not Safe

1. If not X or Y rated, then the caps can be a hazard if connected across the AC line. A fire hazard, a shock hazard, etc. Recommendations such as this are inherently dangerous and should not be espoused to others in a public forum.

The self extinguishing aspect is NOT sufficient to provide enough fire hazard safety, and such experiments should be fused or circuit breakered accordingly

2. A cap value of 55 uF will end up looking like an impedance of approx 50 ohms at 60 Hz. That's a lot of leakage current, well beyond what UL considers safe, and I am sure it violates fire codes as well.

Consider this, with a "normal" AC line circuit, there is not supposed to be a significant voltage difference between the Neutral and the Ground lines. With a 55 uF cap (or more if multiples are used)across the line AT THE COMPONENT, that is no longer the case, and a serious and fatal shock could be delivered from the Neutral line to someone who is earth grounded.

On the whole, this much capacitance is dangerous and too much for the average DIYer or Tweaker to place across the AC line with impunity.

Obviously, you as an individual are free to do as you wish, but to recommend something along these lines to others is unwise and irresponsible.
