Hello, I fitted some extra sockets in a bedroom two years ago, and the customer has said that 2 of the sockets make a high pitched whining noise, all tested at the time readings fine etc, I've attached a video, doesn't sound like arcing to me as it's not a crackling sound? I've told them not to use the sockets for now until I can have a look on Sunday, I can't see how two sockets could have gone faulty any ideas?
