Re: As the old saying goes...
"Of course the main problem is if the ring becomes broken then you risk a fire on the halves of the ring which could now be carrying more than they should."
Exactly. A ring main - a bit like token ring networking - is something that seems like a good idea on paper. But at least a token ring card generally didn't go up in flames.
God knows why here in the UK we persist with fitting our houses with ring mains. I can only think we do it because the europeans all have radials and we can't import none of them crude foreign ideas here!
