The ammendment to the regs stating that cables must now be buried 50mm in the wall would be (I assume) to stop them being damaged by the ubiquitous inch-and-a-half-eight screws.
However, if you had a wall with a cable in a bit of plastic capping running down it and you covered it in plasterboard, then that wouldn't give any protection for any screw from 3/4 inch up.
Simply sticking a screwdriver into the plasterboard and through the capping into the cable would take virtually no effort.
Surely this fouls the rule that cables should be given 'physical protection'.
What do the Pro's think?
Personally I would use metal capping - but is that the rule? Or just common sense?
Obviously metal sheathing is better than plastic but if you look at previuos posts the sheathing is only to protect from plasterers/boarders tools.
Cables are expected to run directly vertical or horizontal from accessories or in allowed zones.It is only outside these zones that a cable must be protected by an earthed metallic conduit for example
