    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
