djk, Believe we refer to this one as TN-C-S (PNB). PNB stands for Protective Neutral Bonding. Its only used here where a single consumer is supplied from a distribution TX, usually used when the consumer owns the TX and metering is carried out at high voltage. It becomes the owners responsibility to earth the CNE Conductor. (Sorry missrd your reference to before the meter) Your still refering to PME. Just as an asside any one use PNB then.
