That makes for interesting reading, but just goes to highlight the concerns that have been expressed here at ECN about the ring -- That it is not foolproof and without very careful planning it is quite possible to overload the cables even without faults, such as a broken phase or neutral.
I note the document mentions the committees' desire to retain the U.K. ring circuit. Thinking of another thread, I don't doubt that it's same bunch who want to adopt the CENELEC-type brown/black/gray phase colors!
Allow me to quote myself:
I'd still rather just see rings abandoned entirely, although I know I'm in the minority in the UK for having that view.
Six months on from that comment, but I stand by it.
And whether the present committees want to retain the ring or not, if we ever do get a Europe-wide standard for wiring I can't see the British ring being a part of it.
