I hadn't heard about that IEC proposal to ban TT, but naturally it would get my vote. [Linked Image] They do seem to like TT a lot in some areas of Europe though, so I imagine there will be as much opposition to that proposal there as there would be in Britain if it were proposed to ban the ring circuit or require Schuko outlets as standard.

Interesting on the HV lines in Ireland. I can see the point about not being trained sufficiently, but any decent electrician who has a thorough understanding of the basics should not have too much trouble adapting to different conditions.

Just look at the variations in HV techniques around the world: Delta vs. wye, solidly grounded neutral vs. floating or impedance-grounded, etc.
