retail vendors. In Europe, CENELEC publishes a list of approved plug and socket technical standards used in the member countries. Argentina IRAM 2073 and 2071 (Type I) The plug and socket system used in Class 1 applications in Argentina is defined by IRAM standards. These two standards are; IRAM 2073 "Two pole plugs with earthing contact for domestic and similar purposes, rated 10 A and 20 A, 250 V AC" and IRAM 2071 "Two pole socket – outlets with earthing contact for 10 A and 20 A, 250 V AC., for fixed installations." The plug and socket system is similar in appearance to the Australian and Chinese plugs. It has an earthing pin and two flat current-carrying pins forming an inverted V-shape (120°). The flat pins for the 10 A version measure and for the 20 A version, and are set at 30° to the vertical at a nominal pitch of . The pin length is the same as in the Chinese version. The earthing pin length is for the 10 A version and for the 20 A version. On the plugs, the pole length is for the 10 A version and for the 20 A version. The most important difference from the Australian plug is that the Argentinian plug is wired with the live and neutral contacts reversed. In Brazil, similar plugs and sockets are still commonly used in old installations for high-power appliances like air conditioners, dishwashers, and household ovens. Although being often called "Argentinian plug," it is actually based on the American NEMA 10-20 standard, and is incompatible with Argentinian IRAM plugs. Since Brazil adopted the NBR 14136 standard which includes a 20 A version, the original motivation to use the NEMA 10-20 plug has ceased to exist. Australian/New Zealand standard AS/NZS 3112 (Type I), used in Australasia This Australian/New Zealand standard is used in Australia, New Zealand, Fiji, Tonga, Solomon Islands, and Papua New Guinea. It defines a plug with an earthing pin, and two flat current-carrying pins which form an inverted V-shape. The flat pins measure and are set at 30° to the vertical at a nominal pitch of . Australian and New Zealand wall sockets (locally often referred to as power points) 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 double-insulated
