What is the mains voltage in Thailand ? UK (BS EN 61558-2-5) and Malaysia (MS IEC 61558-2-5). Shaver supply units must also be current limited, IEC 61558-2-5 specifies a minimum rating of 20 VA and maximum of 50 VA.[12] IEC 61558-2-5 requires sockets to be marked with the shaver symbol defined in IEC 60417-5225, the words "shavers only" are also often used but not required. IEC 61558-2-5 has been adopted as a European CENELEC standard EN 61558-2-5 and also as a national standard in some countries, e.g. For a plug, the values are normally those specified in the relevant standard sheet. Despite this, World Plugs lists seven territories as using only Type C (i.e., no mention of specific plug types whose mating sockets also accept Type C) and twenty-one territories using Type C with no compatible types. World Plugs includes some history, a description of plug types, and a list of countries giving the type(s) used and the mains voltage and frequency. For example, in North America most sockets are attached to a 120 V supply, but there is a 240 V supply available for large appliances. Some countries have more than one voltage available. In some areas, older standards may still exist. Unable to add item to Wish List. 401, "Safety requirements for rewirable and non-rewirable 13A fused plugs for normal and rough use having insulating sleeves on live and neutral pins", NSAI (National Standards Authority of Ireland), (1997), Dublin, International Electrotechnical Commission, Saint Helena, Ascension and Tristan da Cunha, Industrial and multiphase power plugs and sockets, List of current systems for electric rail traction, "Universal socket-outlets – friend or foe? China – installed capacity 221GW ; China is the world leader in wind energy, with over a third of the world’s capacity. Power cords with type A plugs which are rated at only 125 V may present a safety hazard. From Infogalactic: the planetary knowledge core, For further information on each plug and discussion on the different voltages and frequencies used, see. So-called "universal socket" which meets no standard but accepts a number of different plug types. Type J (Swiss) is rated at 10 A and is differentiated from Type N. The Type K rating is not shown. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.[4]. To get the free app, enter your mobile phone number. IEC World Plugs is ambiguous in some areas: it does not reference national technical standards that define the dimensions and tolerances of devices. All voltages are root mean square voltage; the peak AC voltage is greater by a factor of √2, and the peak to peak voltage greater by a factor of 2√2. Voltage, frequency, and plug type vary, but large regions may use common standards. ), Multi-standard sockets are sometimes used in China and some other Asian countries; these are intended to accommodate plugs conforming to various different standards. In the past, Thailand conformed to the American plug and socket standard (types A & B), which, from a safety perspective, was not the wisest choice. It also lists the following territories as using Type C without compatible socket types: Argentina, Bolivia, Cambodia, China, Gibraltar, India, Iraq, Isle of Man, Kuwait, Lebanon, Malaysia, Mauritius, Nepal, Oman, Pakistan, Peru, Singapore, Sudan, United Arab Emirates, Vietnam, Zambia. Plugs will usually mate with sockets which are intended to accept plugs classified under the same letter type, but there is no guarantee of this. |, IEC 61558-2-5 includes the following definitions: (3.1.101), I.S. The last printed edition (listing plugs from A to H) was that of 1998, reprinted in 2002,[6] it includes brief textual descriptions of each type illustrated by a sketch, only Type F (described as a Schuko) is specifically linked to a generally recognized type. Access to electricity, rural (% of rural population) Electricity production from oil sources (% of total) Electricity production from renewable sources, excluding hydroelectric (kWh) In multi-standard sockets, the aperture size for NEMA plugs is often the same for both Line (Hot) and Neutral, which allows a polarized plug to be inserted in either orientation, thus defeating the safety feature. Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. This was updated from time to time and the 1967 version includes some information on plugs,[14] however only 3 types were designated: Type A, illustrated by a US style 2 pin plug, Type B, illustrated by a sketch of a BS 546 type, and Type C, illustrated by a sketch of a BS 1363 type. Mains electricity by country: Ronald Cohn Jesse Russell: Books - Amazon.ca. The system of plug types using a single letter (from A to N) used here is from World Plugs, which defines the plug type letters in terms of a general description, without making reference to specific standards. which provides the main source for this page, except where other sources are indicated. (See History of similar guides section below. Sockets connected to mains voltages above 125 V and which accept Type A or B plugs may be suitable for chargers and power supplies incorporating Type A pins, providing they have a suitable voltage rating. IEC 60884-1 para 6.1 defines the preferred voltage ratings for single phase plugs and sockets as 130 V or 250 V. In the foreword of IEC 60884-1 it states: in order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. The Type N description is of the two variations of Brazilian plug (Brazilian national standard NBR 14136); however, the original plug and socket is defined in IEC 60906-1 and has been adopted as a South African national Standard (SANS 164-2). The United States Department of Commerce published an earlier guide,[6] which is now obsolescent and which has known inaccuracies. (For industrial machinery, see industrial and multiphase power plugs and sockets.) This means that the uninsulated pins of a Chinese plug may become live while there is still a large enough gap between the faces of the plug and socket to allow a finger to touch the pin. In some areas, older standards may still exist. Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. After viewing product detail pages, look here to find an easy way to navigate back to pages that interest you. These include an isolation transformer and usually accept multiple two-pin plug types including Europlug (Type C), Australian (Type I) and BS 4573. Please try again. The Brazilian version is non-compliant with the IEC standard. Every country has differing rules regarding distribution of electricity for portable appliances and lighting. Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. [13] This contained information on voltages used in the cities of many countries, but no information on plugs. Plugs and power cords have a rated voltage (V) and rated current (A) assigned to them by the manufacturer, and these values are required to be marked on the plug. Another possible reason is the use of so-called "universal sockets" in use in some countries, these accept multiple plug types but meet no standards and are not classified by the IEC. Type C is specifically identified as the Europlug (which is defined in EN 50075) and described as a plug which fits into any socket that accepts 4.0–4.8 mm round contacts on 19 mm centres. All voltages are root mean square voltage; the peak AC voltage is greater by a factor of √2, and the peak-to-peak voltage greater by a factor of 2√2. Type M is described as looking similar to Type D, but with much larger pins. one rated for 125 V with a 230 V supply) may constitute a safety hazard. Type G is identified as the fused British plug. Voltages in this article are the nominal single-phase supply voltages. IEC 60884-1 para 9.2 does stipulate that: it shall not be possible, within a given system, to engage a plug with a socket-outlet having a higher voltage rating or a lower current rating. Often different sockets are mandated for different voltage or current levels. The Brazilian version is non-compliant with the IEC standard.

Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. The International Trade Administration of the US Department of Commerce now publishes a web version: Electric Current Worldwide which still does not include the full list of plug types; it does not describe Type M or type N. There are sketches and photographs of each type, but no textual description or references to actual standards. Also, in a socket designed to accept both NEMA and BS 1363 plugs, the polarization can only be correct for one type of plug, so only appliances which do not require specific polarization should be connected. © 2008-2020, Amazon.com, Inc. or its affiliates. Power cords with type A or B plugs which are rated at only 125 V may present a safety hazard. Type D is specifically rated at 5 A. The International Electrotechnical Commission publishes a web microsite World Plugs which provides the main source for this page, except where other sources are indicated. [7] Multi-standard sockets made by Lengon and Somogy Elektronic were classified as serious safety risks, because they allow the user to come into contact with live parts.[8]. The Power subranking score had an 8% weight in the overall Best Countries ranking. Try Prime EN Hello, Sign in Account & Lists Sign in Account & Lists Orders Try Prime Cart. Background information. Some countries have more than one voltage available. The international preferred rating for household plugs and sockets is either 130 V or 250 V; these are the values for normal use, and at which they are tested.
