(someone on the iee forum said they had seen this in a shower area where someone had tried to hang somekind of soap holder of something in the prescribed zones around the shower)
having the nail that the dozy twit is about to knock into a phase conducter connected to earth would be a good thing IMHO
Yep twas me.
It did cause a dangerous situation that would not have happend if plastic capping or no capping at all was used (unless of course metal capping was earthed)
I often see nails for pictures etc in the zones of protection and also see diagonals with metal capping on inviting someone to nail thru the capping - makes me cringe
