Rather than use plastic sheathing/capping, I’ve been using steel capping on all the wiring to existing sockets/light boxes (most of the plaster has had to come off!) & any new ones that have been added, including any cables run in the safe zones.
I’ve bee doing this on the assumption that it would improve safety as a masonry bit will go through plastic but not steel. After re-reading the regs, I’ve now had a horrible thought that perhaps I should have bonded the steel capping to the earth terminal in the box! Is this required or does steel capping qualify a mechanical protection not needing an earth bond.
