Double tapped capacitor cross-connection

@dfreund

It appears to be a capacitor double tapped between a 15 amp circuit and 20 amp circuit. Some DIY line conditioner or something?

@gwells

It is likely a band-pass filter for communications. They are used for home automation systems.

I would not be concerned about the double-tap.

Thanks Christopher!, and @gwells! This makes sense I’ll admit I didn’t perform a quick search on the archives.

Edit:
With that info though, there are still 2 wires under a breaker terminal that appear to only be rated for one wire? Wouldn’t that still be problematic? I believe it is.
