    Why does the UK use rings for sockets?

    I take it you're allowed to use radials for sockets? So why does anyone bother with rings, seems like extra hassle to me.

    Just checking my understanding of spurs off rings

    Have 18th ed and page 505 does say an unfused spur should feed one twin socket outlet. However if a 13amp fused spur is then connected to this and then to another socket is this not permissible? I can't see any potential for cable overloading? Thanks
