Why does the UK use rings for sockets?

[telectrix]

My final word on rings......
If the circuit was a square. the electrons would
have difficulty at the corners, so a ring is more efficient.

The main problem with the ring circuit is it allows small CU's and they get tucked into all sorts of inaccessible space's, the French regulations are strict on the placement of the CU, can't be in a cupboard unless facing forward within 50mm of the front, height from the floor, latest regulations have communication provisions in a parallel board, admittedly I don't know why you would need a telephone point in the toilet.

There always should have been a regulation on access space and similar for the CU placement (or fuse board in its day). But there was not and I don't see it ever being introduced for existing properties under EICR sort of checks. Really it should be a buildings control issue.

I really don't see how RFC vs. radial matters there as such problems are already in place.

AFDD cost, now there is something to consider...

EAWR 15, admittedly it would only apply for the contractors and not the homeowner but still.
