英式标准插头（品字形插头） United Kingdom/Ireland

        英式标准插头（品字形插头）按BS 1363 制造标准执行，也叫英标。自1962年至今英国官方插头标准一直沿用BS 1363。 英标也用在爱尔兰、香港、马来西亚和新加坡等地区。英国标准的插头是品字形、矩形柱状，截面大、耐受大电流，是众多插头标准里最安全的插头之一。英标电源插座有保护门设计，可以防止异物插入或者防止误插入，更加安全可靠。插头插座是强制接受英国ASTA测试认证机构的认证和电器测试。英标插头的电气参数是 3-13A/250VAC

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.
