Nothing wrong with putting a capacitor across an AC source if you carefully choose the capacitor size (microfarads and volts) and capacitor type (not a polarized electrolytic, for example).
Some capacitors are perfectly happy to withstand a particular DC voltage, with the possibility of some smaller amplitude hum current imposed on that, but not an AC waveform whose peak value is close to the nominal capacitor design voltage.
Other capacitors, such as motor run capacitors, are designed to take full voltage excursions (possibly with limited current) at 60 Hz without damage.
A randomly chosen capacitor with the right voltage limit and a lot of microfarads could indeed destroy itself quickly based on the current or the constant polarity reversals. Too large a capacitor will indeed draw enough current to trip a breaker.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

Yup! I could have put motor matching cap on every motorized item i have. But that like putting GFI on every outlet. 1 and done old timers got it done without building complicated circuits. Just need to understand your purpose/requirements. I got hit for using the wrong terminology by using the term harmonic hum on ceiling fans

You've been missed around here. The level of BS coming through has been pretty high lately.
Hope all is well.2.2kw Suntech mono, Classic 200, NEW Trace SW4024Comment
