240 VOLT PLUG WIRING PLUS

”A socket-outlet that is rated at not more than 10 A, installed for the connection of a fixed or stationary appliance or a luminaire and that is not readily accessible for other purposes, need not be controlled by a switch'.” (Such a socket-outlet and the mechanism used is shown on the left.) 'A socket-outlet that is switched by the insertion and withdrawal of the plug shall be deemed to meet the requirements.(subject to the current rating of the switch to be at least equal to the (a) total current rating of the sockets concerned or (b) the current rating of the overcurrent protection device concerned, whichever is the lesser value.) 'A single switch may be used for the control of two socket-outlets located immediately adjacent to each other'.The benefits claimed for their use in these applications include up to 50% faster installation, due to the reduction in the stripping, twisting and screwing down processes. If required, such dual socket-outlets can be obtained (at additional cost) using insulation displacement as a means of connecting to the supply conductors, as can be seen in the illustration - below right. (One 'rocker' switch has been disassembled to show its operation.) They are not available separately but only integrally with power cords specifically designed for the purpose.Ī view of the wiring side of a typical dual socket-outlet is also shown on the right, together with an annotated view of the mechanism, without the front cover. double insulation) and these plugs are rated at a maximum of only 7.5 amps. Such plugs are only to be used for devices where other safety standards are in use (e.g. There are unearthed versions of the plug used with this outlet having only the two flat inverted V-aligned pins, without the earthing pin. 'Shuttered' socket-outlets are available, but these are not required by regulation. Ī standard socket-outlet provides a nominal voltage of 230 volts RMS at a maximum of 10 amps and always includes an earth connection. The pins are arranged at 120° angles around a common midpoint, with the active and neutral centred 7.92 mm ( 5⁄ 16 in) from the midpoint, and the earth pin centred 10.31 mm ( 3⁄ 8 in) away. The flat blades measure 6.35 by 1.6 mm ( 1⁄ 4 by 1⁄ 16 in) with the active (line) and neutral pins 17.35 mm ( 11⁄ 16 in) long set 30° to the vertical and the vertical earth pin being 20 mm (0.787 in) in length.

The mains frequency is 50 Hz in all these countries.ĭescription Dual 3-pin socket-outlet construction Switched dual 3-pin socket-outlet Socket-outlet, using insulation displacement as a means of connecting to low voltage (230 V) supply conductorsĪS/NZS 3112 compliant plugs have two flat pins forming an inverted V-shape plus a vertical earthing pin. Voltage adapters using a transformer may be required to overcome the problem.

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. Differences in voltage may give rise to compatibility issues, especially for travellers and those purchasing appliances overseas or online. 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. The voltage in New Zealand, Fiji, Tonga and Papua New Guinea remains at a nominal 240 V, and in the Solomon Islands it is 220 V.

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. (Note that, in a single phase installation in Australia/New Zealand, the 'Line' or 'Phase' connection is referred to as the 'Active' connection.) 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. 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. Double insulated appliances omit the earth pin. The plug consists of two flat pins forming an inverted V-shape, plus a vertical earthing pin below them. The International Electrotechnical Commission (IEC) 'world plugs' Web site calls this plug Type I. The standard is used in Australia, Argentina, New Zealand, Fiji, Tonga, Solomon Islands, Papua New Guinea and several other Pacific island countries.
