I had a failure of a Legrand Mosaic single socket, this was the second one to fail so I am not very impressed with what is meant to be a premium quality fitting. On removing the faceplate I found that the earth wire was not connected as can be seen from the appended photo. A basic dangerous error but in keeping with the many other electrical errors such as the cables across a cupboard floor (see earlier post). I also noticed that the metal back box was not connected to the earth, a sign again of very poor installation practice.
Has anybody else had failures of Legrand Mosaic sockets?
