  BS 1363 (See map)
13A/230V/50Hz
The official plug standard in the United Kingdom since 1962 is the BS 1363 plug. (The previous plug standard was BS 546, still found in older buildings.) The BS 1363 plug is also used in Ireland, Hong Kong, Malaysia, and Singapore. British standard BS 1363 requires use of a 3-wire grounded and fused plug for all connections to the power mains (including Class II, 2-wire appliances). The BS 1363 plug contains a BS 1362 fuse, which is designed to protect the cord and branch wiring back to the branch circuit protector installed in the building. British power outlets incorporate shutters on line and neutral contacts to prevent someone from pushing a foreign object into the socket. For more information on the British fusing requirements, see Why does the United Kingdom/Ireland plug have a fuse?.
Appliances tested and approved by British agencies can only use approved plugs, and these are tested by ASTA-BEAB to BS 1363. ASTA requires that their mark be molded into the plug.
The plug is rated from 3–13A/250VAC, depending on the fuse. Standard Interpower™ British cords and cordsets are approved by ASTA and carry the ASTA-BEAB.
