Type I plugs and sockets from different countries have different pin lengths. This means that the uninsulated pins of a Chinese plug may become live while there is still a large enough gap between the faces of the plug and socket to allow a finger to touch the pin.
即係話 GB 1002‐2008 Type I 插腳長度唔同,AS/NZS 3112 (Type I) 插腳短啲。 大陸插頭,插落澳洲嘅插蘇,有機會未插到落底就通電。
