The MI instructions, in the case, are an illustration that the switch needs earthing not a prescription on how exactly to achieve this.the reasons i would give it a C3 is that it does not comply with MI ( as westie pointed out), and if the screws were removed for decorating or whatever, a fault on the switch would not trip MCB. therefore it "is improvement recommended. ", because i say so (smiley).
Jesus, the day I make my professional decisions based solely on what some monkey in the BG back office put together on his etch-a-sketch, I'll top myself.
