Australasian switched 3-pin dual power point (socket)
This plug, used in Australia, New Zealand, Fiji, Argentina, Solomon Islands and Papua New Guinea, has a grounding pin, and two flat current-carrying pins forming an upside down V-shape.[19] The flat blades measure 6.5 by 1.6 mm (0.256 by 0.063 in) and are set at 30° to the vertical at a nominal pitch of 13.7 mm (0.539 in). Australian and New Zealand wall sockets almost always have switches on them for extra safety, as in the UK. An unearthed version of this plug with two angled power pins but no earthing pin is used with small double-insulated appliances, but the powerpoint (wall) outlets always have three pins, including a ground pin.
There are several AS/NZS 3112 plug variants,[20] including ones with larger pins and/or differently shaped ground pins used for devices drawing 15, 20, 25 and 32 amps. These sockets accept plugs of equal or of a lower current capacity, but not of higher capacity. For example, a 10 A plug will fit all sockets but a 20 A plug will fit only 20, 25 and 32 A outlets.
Australian 2005 standard power plug
Australasia's standard plug/socket system was originally codified as standard C112 (floated provisionally in 1937, and adopted as a formal standard in 1938), which was superseded by AS 3112 in 1990. As of 2005, the latest major update is AS/NZS 3112:2004, which mandated insulated pins[21] by 2005 at the point of sale in all Australian States and New Zealand. However, equipment and cords made before 2003 can still be used.
Chinese sockets accepting plug Types A, C (upper) and I (lower, standard)
CPCS-CCC (Chinese 10 A/250 V)
Although the pins on the Chinese plug are 1 mm (0.039 in) longer, the Australasian plug can be used with mainland Chinese socket. The standard for Chinese plugs and sockets is set out in GB 2099.1–2008 and GB 1002–2008. As part of China's commitment for entry into the WTO, the new CPCS (Compulsory Product Certification System) has been introduced, and compliant Chinese plugs have been awarded the CCC Mark by this system. The plug is three wire, earthed, rated at 10 A, 250 V and used for Class 1 applications.
In China, the sockets are installed upside-down relative to the Australasian ones.
China also uses American/Japanese Type A sockets and plugs for Class-II appliances. However, the voltage across the pins of a Chinese socket will always be 220, no matter what the plug type
