Australian AS/NZS 3112 SAA Power Cord, Plug, Flexible Cable Standard

Australian 2005 standard power plug with insulated pins For more details on this topic, see AS 3112.Australasian switched 3-pin dual power point (socket)

The plug used in Australia, New Zealand, Fiji, Tonga, Argentina, Solomon Islands, Papua New Guinea and China has an earthing pin and two flat current-carrying pins forming an upside down V-shape.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 sockets always include an earth pin.

There are several AS/NZS 3112 plug variants,including ones with larger or differently shaped pins used for devices drawing 15, 20, 25 and 32 A. 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 sockets.

Australia'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codified as standard C112 (floated provisionally in 1937, and adopted as a formal standard in 1938), which was superseded by AS 3112 in 1990. The requirement for insulated pins was introduced in the 2004 revision.The current version is AS/NZS 3112:2011, Approval and test specification - Plugs and socket-outlets.

3 Prong Power Plug

Australia SAA Standard 3 Prong Power cord,The plug in Australia is 240V AC, 50Hz. Standard 3 prong earthed power outlets are rated at 10Amps and are usually switched. The 3-flat-pin plug is used in all states of Australia (including its external territories), New Zealand, Although the configuration is similar to mains plugs used in mainland China, dimensional differences to the plug body may be incompatible with recessed cord socket and prevent Chinese-compliant CPCS/CCC (CCEE) plugs from being legally sold/used in Australia. Argentina also uses a similar 3-flat-pin configuration as Australia, but with slight dimensional differences and with the active and neutral wires being reversed. These important differences prevent the Argentina-compliant IRAM plugs from being legally sold/used in Australia as incorrect polarity may present an electrical safety hazard.

The Australia power cord configuration is now Australian Standards AS/NZS 3112:2000 and AS/NZS 3112:2004 for Australian power plug now define the requirements for the insulation of the Active and Neutral pins of the plug. 15Amp and 20Amp configurations of the mains plug and outlet are also defined by the standard.

The following picture shows the Australia power cord configuration.

Plug with Insulated Pins

Australia Power Cord Plug with Insulated Pins,Australian Standards AS/NZS3112:2000 and AS/NZS3112:2004 for AustraliaPower Cord Plug define the requirements for insulating the Active and Neutral pins of the plug. These requirements were introduced in response to a number of incidents (including fatalities) involving both mains-plugs and plug-in-devices where a metal object (such as a knife blade, a metal blind slat or a sheet of metal) came into contact with a plug pin that was partially removed from a socket and resulted in an electrical shock.

Since 3 April 2005 insulated live pins have been mandatory for all plugs (and appliances with integral pins). Approval Certificates for items having non- insulated pins were cancelled on that date. In the interests of enhanced electrical safety and to ensure rapid dispersion into the marketplace, each Australian State and Territory and New Zealand Electrical Regulator required that all electrical equipment was supplied with insulated pin plugs, at all points of sale, by 3 April 2005.

Power Cords
Australia power cord plugs with Australian SAA certification are built to the AS 3112 and IEC standards for Australia AC power cord applications also known as Australian mains power lead,In Australia,the electricity supplied by the normal wall inlet is called the "mains power system" and therefore Australia power cords are often referred to as Australia mains leads,Australia mains cords,Australia mains cables,Australia line cords and mains power leads.


The plug matching the socket outlet pictured on the left, used in Australia, New Zealand, Fiji, Papua New Guinea and many Pacific Island countries has two flat pins forming an inverted V-shape plus an earthing pin.Australia 10A power cordThese flat blades measure 6.35 by 1.6 mm with the Active and Neutral pins of 17.35 mm in length set 30° to the vertical on a nominal pitch of 13.7 mm and the Earth pin being 20 mm in length.A standard power outlet Australia provides a nominal voltage of 230 volts at a maximum of 10 amps and always includes an earth connection. There are unearthed versions of the plug used with this outlet having only the two flat inverted V-aligned pins, without the Earthing pin. Such plugs are only to be used for devices where other safety standards are in use (e.g. double insulation) and these plugs are rated at a maximum of only 7.5 amps. They are not available separately but only integrally with power cords specifically designed for the purpose.If required,Australia socket outlets now can be obtained (at additional cost) utilizing insulation displacement as a means of connecting to the supply conductors, as can be seen in the illustration - The benefits claimed for their use in these applications include up to 50 percent faster installation, due to the reduction in the stripping, twisting and screwing down processes.


IEC 60320 power cables come in normal and high-temperature variants, as well as various rated currents. The connectors have slightly different shapes to ensure that it is not possible to substitute a cable with a lowerAustralia IEC C5 power cordtemperature or current rating, but that it is possible to use an overrated cable. Cords also have different types of exterior jackets available to accommodate environmental variables such as moisture, temperature, oils, sunlight, flexibility, and heavy wear. For example, a heating appliance may come with a cord designed to withstand accidental contact with heated surfaces. Worldwide, more than twelve different types of connectors are used for fixed building wiring. Products sold in many different markets can use a standardized IEC 60320 connector and then use a detachable power cord to match the local electrical outlets. This simplifies safety approvals, factory testing, and production since the power cord is a low-cost item available as a commodity. Note that the same types of appliance-side connectors are used with both 110 V and 230 V power cables, so care must be used when moving appliances between countries with different voltage standards — substituting a power cord that matches local power outlets will result in an incorrect voltage being applied to the appliance or equipment. Unless explicitly labelled as capable of handling local voltages, this is very likely to damage or destroy the appliance. Some devices have a slide-switch to adapt to different voltages, or wide-ranging power supplies.
