Since the subject of vibration through receptacle covers was mentioned, I'd like some advice. The covers on my duplexes are not perfectly flush to the drywall so I'd like to secure them.
I have two 20A dedicated lines coming from a subpanel, then wired to Hubbell duplexes. I'm using large non-magnetic stainless steel covers which are very rugged.
I want to insulate the inside of the covers to insure a more secure fit. Should I use rubber or Sorbethane, or would there be any benefit in using carbon fiber fabric or tape?
All this talk about buying Oyaide carbon fiber covers has me wondering.
