Obviously metal back boxes usually cannot be seen or touched because they are in the wall. Been out today to a lady who has two metal backboxes from sockets in her kitchen which are in a wall made of a single layer of wood with a plasterboard on the kitchen side. The backs of the boxes and cable entries are easily accessible on the other side of the wall, which is the entrance to the cellar. So what?
Well, there are a lot of unused screwholes in the boxes, and her son poked an object through one and luckily tripped the RCD. My point or question is, in this situation should the holes be sealed? I used what I had to hand, a nut and bolt on each hole.
