Rules regarding buried earth cables

Richard Cyphus

Nothing I can see in the regs differentiates between an earth cable and T&E when it comes to the rules regarding buried cables.

But what I can't work out is why it's OK to run a T&E in EARTHED conduit outside of safe zones, but NOT an earth cable, since from the perspective of a nail/screw penetrating into the wall and catching the cable or conduit - there is no difference.

    Generally it’s fairly obvious if someone cuts through a twin and earth cable because there’s a big flash and a bang and/or things stop working, but with an earth conductor damage may not be immediately evident, it is also less likely to get repaired.

    So a buried earth conductor really needs more mechanical protection, not less.
