Like I said,
even ESQCR doesn't describe a proper PME as recognised by most other developed countries in the world,
have you checked the conditions that are required by 2012 for a TNCS to be called PME ?
I think you may find them somewhat more stringent.
You will find that most, if not all new DNO supplies are meeting PME conditions.
Then you have the god knows how many old supply cables, that were previously TN-S but now being converted to PME because of there lead sheath's deterioration etc. There are many such cables, that are in the process of being converted, but do not yet meet full PME conditions. I suppose you could call these situation TNC-S supplies!!! ....Conversion costs money, so it's not going to all happen over night so to speak, but all i'm sure, all will eventually meet PME conditions, just maybe later rather than sooner ...lol!!! .
