Indeed, and mine was really just suggesting that the scenario being discussed was an extremely improbably one, and far less probably than a hazard which could fare more easily be invoked by an unsupervised child
[ As has been said, I presume that you are talking about
exposed-conductive-parts.]
I suppose I was asking for trouble by writing those words, but the real point is that this fitting is not an 'exposed-c-p', which is a metal part of an electrical item which 'can be touched'. The regulations require that the bottom and sides of an enclosure (enclosing live parts) be IP2X, which essentially means that the surface may not have holes in it which will allow an object 12 mm in diameter (e.g. a finger) to be inserted - which the small hole in the OP's fitting clearly would not permit.
In fact, the OP's (wooden) 'enclosure is not really enclosing live parts, since there are no parts within it which are loive in the absence of a fault. If one accepts wood as an insulator, it could be argued that his fitting is therefore essentially 'double insulated', since it would require two 'faults' before anything live could be touched.
