Quite. As I said, it was only at the 11th hour that it was dropped (as a 'requirement') from BS7671, so it's presumably only a matter of time before it 'happens'All installations should have their own earth electrode, such things are now recommended in BS7671. Most other countries have required them for ever.
Exactly - as I said.However shoving in one of the usual thin copper clad steel rods about 1m long will achieve very little, the resistance will be too high to have any meaningful effect.
Indeed so - but that's simply not going to happen - at least, not for anything but possibly future new-builds.On the other hand, installing a substantial metallic grid under your driveway would have a very low resistance, possibly so low that failures
IF the local earth were ever that good, one could presumably forget regarding it as a 'CNE' and just regard it as a 'N' (and hence not connect it to the installation's earthing system), in which case a 'broken CNE' would no longer be something for people to worry and write reams about - since it would merely result in a 'loss of supply', just as would a 'broken L'.such as a broken CNE conductor could be entirely concealed by the presence of it.
