caption_attribution_description: English: Australian AC power plug with insulation on Line (Active) and Neutral pins. Note that the Earth pin is longer than the others; this helps ensure that the Earth pin is the first to make contact and the last to break.
context_page_description: AS/NZS 3112 is the harmonised Australian and New Zealand standard for AC power plugs and sockets. The standard is used in Australia, New Zealand, Fiji, Tonga, Solomon Islands, Papua New Guinea and several other Pacific island countries. The International Electrotechnical Commission "world plugs" Web site calls this plug Type I.
  The plug consists of two flat pins forming an inverted V-shape, plus a vertical earthing pin below them. Double insulated appliances omit the earth pin. When viewing a plug from the rear, and the earth pin downwards, the top left pin is active and the top right pin is neutral. The shank of the active and neutral pins of every 10 amp and 15 amp flat-pin plug sold after 3 April 2005 are required to be insulated, in accordance with AS/NZS 3112:2000.
  Since 2000, the nominal voltage in most areas of Australia has been 230 V, except for Western Australia and Queensland which both remain at 240 V, though Queensland is transitioning to 230 V. The voltage in New Zealand is also 230 V. In Fiji, Tonga and Papua New Guinea it is 240 V, and in the Solomon Islands it is 220 V.
context_section_description: AS/NZS 3112 is the harmonised Australian and New Zealand standard for AC power plugs (male) and sockets (female). The standard is used in Australia, New Zealand, Fiji, Tonga, Solomon Islands, Papua New Guinea and several other Pacific island countries. The International Electrotechnical Commission (IEC) "world plugs" Web site calls this plug Type I.
  The plug consists of two flat pins forming an inverted V-shape, plus a vertical earthing pin below them. Double insulated appliances omit the earth pin.

  (Note that, in a single phase installation in Australia/NZ, the "Line" or "Phase" connection is referred to as the "Active" connection.)
  Since 2000, the nominal voltage in most areas of Australia has been 230 V, except for Western Australia and Queensland which both remain at 240 V, though Queensland is transitioning to 230 V. The voltage in New Zealand is also 230 V. In Fiji, Tonga and Papua New Guinea it is 240 V, and in the Solomon Islands it is 220 V. The standards of China and Argentina also use the type I plug and socket, though the live (active) and neutral pins are reversed in Argentina, and the plugs and sockets in China are fitted with earth upper most and live on the right. In both countries the voltage is 220 V. Differences in voltage may give rise to compatibility issues, especially for travellers and those purchasing appliances overseas or online. Most 230V equipment will work with voltages from 220-240 without issues but connecting a 110 volt appliance to a 230 volt outlet can damage the appliance. Voltage adapters using a transformer may be required to overcome the problem. The mains frequency is 50 Hz in all these countries.
