AIUI, it's not allowed, at least, not in UK - i.e. CNE conductors are not allowed within UK installations.Just wondering what places do you see TN-C (not to be confused with TN-C-S) as a earthing system past DNO's equipment and property?

I thought it was still permitted in mines? But not allowed anywhere else.
When I was at college a lecturer said he had been involved with the install of TNC system in a block of flats while he was an apprentice..... Wired in pyro so that must be at least 50 years ago
As do tramways. Running rails are a combined neutral and earth, overhead wire or third rail is the live conductor.As far as I am aware railways use TN-C for powering electric trains.
