Museum of Plugs and Sockets: IEC standard household plug
Archived from the original on It ensures that the protective-earth pin establishes contact before the line and neutral pins. From Iex, the free encyclopedia. They are nominally Old outlet and plug, Middle: The pins have a diameter of 4. The sockets are small enough that two can be installed in the space taken by a single Schuko or BS socket.

However, the pins of the Type L 10 A are 4 iecc in 609062 as in the Europlug and the earth pin is aligned with the two others no offset is presentmaking the Italian plug unpolarized. South Africa and Brazil are the first countries in the world that have introduced the standard. NBR defines plugs and sockets for either 10A or 20A. Views Read Edit View history. Retrieved 13 January Modern injection moulding technology enables robust and safe plugs to be smaller than the Schuko and BS systems, which were designed in the early and mid 20th century respectively.
Old Swiss type 12 plug without partially sleeved line and neutral pins. Offset of earth pin distance from center line. It was concluded with wide participation of the manufacturers of plugs and sockets and of electrical and electronic equipment, in July ofwith the publication of the norm ABNT NBR The two types share several characteristics, but Swiss plugs do not fit in IEC irc v. An advantage of the IEC plug types is smaller physical sizes.
NBR does not require shutters on the apertures, a further source of non-compliance with IEC Mains power connectors IEC Practical consequences of the irc of the new standard are among others: Pins are thicker compared to 10A plugs 4.
Moreover, the Italian plug is rated for up to 10 amperes oec a ampere version exists with different and incompatible sizewhile the IEC plugs are rated for 13 amperes. In the European Union EU published recommendations advising against the harmonisation of domestic plug and socket systems in the EU. According to the National Institute of Metrology Standardization and Industrial Quality in Brazil, the Brazilian Association of Technical Standards “began discussing the creation of a standard for plugs and sockets Ambiguity between line and neutral.
The live pins are in contact while exposed. Therefore, there is no compatibility between these grounded 3-pin plugs. There is no connection for the earthing contact.
The IEC and BS systems have some common safety features in that plugs and sockets are polarized, and that sockets are required to have shutters for the line and neutral pins.
The standard was published in as ICE IEC plugs are rated up to 16A. Old and new multi-standard socketRight: Beginning January 1st, new residential, commercial and industrial wall outlet installations must comply with this new standard, and beginning August 1st, imported electrical devices must comply with NBR regulations.

The International Electrotechnical Commission IEC has developed an international standard V household plug system, to be used one day everywhere in Europe and other countries with V mains. Sockets have a 10 mm deep recess, which eliminates the possibility of touching pins under tension with fingers or any object.
The IEC plugs are smaller than any other European plug with 16 A rating, being only slightly larger than the 2. Attempts to standardize European electrical power distribution started already in the early s! Brand name of socket and plug: Insulating sleeve around base of L and N pins. However, the latter has smaller diameter pins 4. IEC plugs are similar in size and shape to the Europlugwith the front profile being a flat hexagon. Distance between line and neutral pin.
This page was last edited on 25 Decemberat Socket for new plugs only. In common with the Europlug there is an insulating sleeve around the base of the line and neutral pins.
Details are given below. However, since 1 Januaryonly type 11 and 12 plugs with partially sleeved line and neutral pins are allowed to be imported and distributed in Switzerland to reduce the risk of electrical shocks. Retrieved from ” https: There are a number of non-compliance issues with IEC Sockets are jec to have shutters for the line irc neutral apertures. The 3-pin version has a round protective-earth pin of the same length and diameter as the line and neutral pins, but with no insulating sleeve.
