PME vs TN-C-S

AncientMariner
Are PME and TN-C-S supplies exactly the same?  Or does PME also have requirements regarding the number and relative location of suppliers earthing rods?

I am thinking here where the DNO replaces a length of failed 4-core (3-phase + Neutral) PILC cable with Wavecon or similar cable which has a combined Neutral and Earth conductor.  The average consumer would not know that their electricity supply's method of earthing had been changed.

    Sure - I think the phrase we would use is "reliably at or around earth potential"


    It was just a bit of an insight into how PME services may be delivered in practice by a DNO or similar, for compliance with ESQCR
