BS1363
Plugs and sockets for electrical appliances not hardwired to mains electricity originated in the United Kingdom in the 1870s and were initially two-pin designs. These were usually sold as a mating pair, but gradually de facto and then official standards arose to enable the interchange of compatible devices. British standards have proliferated throughout large parts of the former British Empire. BS 546, ''Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V'' is a British Standard for three-pin AC power plugs and sockets. Originally published in April 1934, it was updated by a 1950 edition which is still current, with eight amendments up to 1999. BS 546 is also the precursor of current Indian and South African plug standards. The 5 A version has been designated as ''Type D'' and the 15 A as ''Type M'' in the IEC 60083 plugs and sockets standard. BS 546 plugs and sockets are s ...

Electrical Wiring In The United Kingdom
Electrical wiring in the United Kingdom is commonly understood to be an electrical installation for operation by end users within domestic, commercial, industrial, and other buildings, and also in special installations and locations, such as marinas or caravan parks. It does not normally cover the transmission or distribution of electricity to them. Installations are distinguished by a number of criteria, such as voltage (high, low, extra low), phase (single or three-phase), nature of electrical signal (power, data), type and design of cable (conductors and insulators used, cable design, solid/fixed or stranded/flexible, intended use, protective materials), circuit design (ring, radial), and so on. Electrical wiring is ultimately regulated to ensure safety of operation, by such as the building regulations, currently legislated as the Building Regulations 2010, which lists "controlled services" such as electric wiring that must follow specific directions and standards, and the ...

AC Power Plugs And Sockets
AC power plugs and sockets connect electric equipment to the alternating current (AC) mains electricity power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. A proliferation of types developed for both convenience and protection from electrical injury. Today there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. Coordination of technical standards has allowed some types of plug to be used across large regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Some multi-standard sockets allow use of several types of plug; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Publicly Available Specification
A Publicly Available Specification or PAS is a standardization document that closely resembles a formal standard in structure and format but which has a different development model. The objective of a Publicly Available Specification is to speed up standardization. PASs are often produced in response to an urgent market need. Background BSI Group develops PASs in the UK, while the International Electrotechnical Commission develops international PASs in the arena of electrical, electronic and related technologies, and the International Organization for Standardization develops international ISO PASs. BSI Group pioneered the PAS format. Under the BSI model, any organization, association or group who wish to document standardized best practice on a specific subject, can commission a PAS, subject to the BSI Group, BSI acceptance process. A British Standard and a PAS must reach full consensus between all stakeholders on technical content. The timescale for the development of a PAS can ...

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Low Voltage Directive
The Low Voltage Directive (LVD) 2006/95/EC is one of the oldest Single Market Directives adopted by the European Union before the "New" or "Global" Approach. The Directive provides common broad objectives for safety regulations, so that electrical equipment approved by any EU member country will be acceptable for use in all other EU countries. The Low Voltage Directive does not supply any specific technical standards that must be met, instead relying on IEC technical standards to guide designers to produce safe products. Products that conform to the general principles of the Low Voltage Directive and the relevant particular safety standards are marked with the CE marking to indicate compliance and acceptance throughout the EU. Conformance is asserted by the manufacturer based on its conformity assessment. The new version of Low Voltage Directive version of 2014/35/EU, dated 26 February 2014 and is applicable from 20 April 2016. The new version aligns with the New Legislative Fr ...

Retained EU Law
The European Union (Withdrawal) Act 2018 (also known as the Great Repeal Act) is an Act of Parliament, Act of the Parliament of the United Kingdom that provides both for repeal of the European Communities Act 1972 (UK), European Communities Act 1972, and for parliamentary approval to be required for any withdrawal agreement negotiated between the Government of the United Kingdom and the European Union. The bill's passage through both Houses of Parliament was completed on 20 June 2018 and it became law by Royal Assent on 26 June. The Act is to enable "cutting off the source of EU law in the UK ... and remove the competence of EU institutions to legislate for the UK".Summary The Second May ministry, 2017–2019 Government of Theresa May regarded it as the most significant constitutional legislation to have ...

BSI Group
The British Standards Institution (BSI) is the national standards body of the United Kingdom. BSI produces technical standards on a wide range of products and services and also supplies certification and standards-related services to businesses. History BSI was founded as the Engineering Standards Committee in London in 1901.Robert C McWilliam. BSI: The first hundred years. 2001. Thanet Press. London It subsequently extended its standardization work and became the British Engineering Standards Association in 1918, adopting the name British Standards Institution in 1931 after receiving a Royal Charter in 1929. In 1998 a revision of the Charter enabled the organization to diversify and acquire other businesses, and the trading name was changed to BSI Group. The Group now operates in 195 countries. The core business remains standards and standards related services, although the majority of the Group's revenue comes from management systems assessment and certification work. In ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...
