Lots of caps are designed for ac use, not just X and Y types, and go into the many Uf range. I have been using Aerovox lighting caps for years and years, each of which is 55uf, these are designed for ac use and designed to be self extinguishing. Supposedly there is no shock danger if used across the line. I have checked this out with an electronics engineer and he concurred. Although someone at Aerovox told me they were Type X he must have been incorrect as they are not rf suppression caps and are too high a value. Designed for AC, designed not to catch fire I see no safety problem. I do make sure that a high quality plug and thick wire is used to take whatever heat accrues in the plug and don't touch the leads. No shock, no fire, no problem, yes? If this is dangerous in some fundamental way please give a detailed scientific explanation why. Of course you can get shocked if they are unplugged with a charge and you touch them. Thanks, Tweaker EDIT: 8/12 I should have said that I see very little safety problem not "no" safety problem. Even the WIMA type X capacitors can catch fire and are self extinguishing. Also because of the concerns about this issue I rescind any recommendation explicit or implied. The Aerovox dry type lighting caps may or may not be self healing. I am in contact with Aerovox over that issue, there is some confusion over this at their end. They are for continuous use. Not motor start. They are plugged in and out on a circuit with a breaker away from the cap, regular house protection breaker. T
