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.

    There is nothing to stop you running a cpc in the conduit, but there may be the option of using the conduit itself as the cpc.

    Or perhaps by "earth cable" you mean the earthing conductor or a bonding conductor, which may need to be chased into a wall? Taken as a whole, I would say that a strict interpretation of 522.6.201 to 204 includes them, but common sense does not.
