The Australian Mains Plug (AS/NZS 3112)
The standard domestic mains power supply in Australia is nominally 230V AC, 50Hz. Standard 3-pin earthed power outlets are rated at 10Amps and are usually switched. The 3-flat-pin plug design, standardized as AS/NZS 3112, is used throughout Australia, New Zealand, Papua New Guinea, and the Solomon Islands.
The Australian mains plug configuration was originally formalised as Standard C112 in 1938, and is now designated AS/NZS 3112. The latest standards mandate the insulation of the Active and Neutral pins for enhanced safety.
The following diagram shows the Australian plug wiring configuration.
