BS 1363
BS 1363 is a British Standard for AC power plugs and sockets in the United Kingdom, rated for up to 250 V and 13 A. These rectangular 3-pin plugs correspond to Type G according to the IEC. Distinctive characteristics of the system are shutters on the line and neutral socket holes, and a user replaceable fuse in the plug. The BS 1363 is a one plug solution being an alternative to the older round-pinned, BS 546 socket-outlet family of four differing non- interchangeable socket-outlet types.
