I think despite the IEE's support for the ring system that that single fundemental flaw would justify Cenelec banning it in new installations. Is simply isn't fundementally safe and relies on good installation practice.
and Despite the fact that I think BS1363 is a good, sturdy well designed connector the fact that it's possible to insert a Europlug into the outlet and end up with a portable applience being protected only by a 32A fuse is unacceptably dangerous. Most people know how to open a UK socket shutters with a pencil and you do see tourists and locals alike using 2-pin plugs in BS1363 outlets with no adaptor.
The simple fact is that it works quite well, the sockets appear to generally make good contact with the europlugs and hold them very firmly in place.
Since all EU flexible cables are designed to handle 16A it would make an a lot more sense to fuse the sockets than the plugs.
Do you think we could ever see a fused UK socket that is designed to accept 3-pin UK plugs and thin 2-pin Europlugs?
