Similar converters are available for a variety of other plug types. They also require that all mains appliances for domestic use in the UK be supplied with approved BS 1363 plugs, but there is an exception for plugs fitted to shavers and toothbrushes which are normally a UK shaver plug (BS 4573) but may also be a Europlug (BS EN 50075). In an appendix to the main report (July 1944), the committee proposed that a completely new socket-outlet and fused plug should be adopted as the "all-purpose" domestic standard. Theoretically, such protection could have been designated either within the socket or within the plug. This plug corresponds to Type M in the IEC table. Shaver supply units must also be current-limited; BS EN 61558-2-5 specifies a minimum rating of 20 VA and maximum of 50 VA.[33] BS 4573 and BS EN 61558-2-5 both require sockets to be marked with the shaver symbol defined in the IEC Standard 60417-5225; the words "shavers only" are also often used but not required. Different standard systems of plugs and sockets … Five-bed £1.3m home is leaving house-hunters feeling ‘ill’ because of the bizarre number of plug sockets. According to British author John Mellanby[22] the first plug and socket in England was introduced by T. T. Smith in 1883, and there were two-pin designs by 1885, one of which appears in the (British) General Electric Company catalogue of 1889. [79], The purpose of these adaptors is to accept the 2 pin plugs of shavers, they are required to be marked as such. 11, Electrical Installations, Appendix, "Safety in the home", Southern Electricity & RoSPA | 00-980-05 |, October 1978, GB Patent 294,689: "Improvements in or in connection with Plug and Socket Connectors for Electric Circuits." BS 1363-1:1995 +A4:2012 remained current until 31 August 2019. Early types were available fused in both poles; later types fused in the line only and provided an earth pin. Great Savings & Free Delivery / Collection on many items ... Vintage Art Deco White Bakelite Type UK Plug WG Small Round 3-Pin 2A 1940s 50s. September 1995: BS 1363-3:1995 "13 A plugs socket-outlets adaptors and connection units - Part 3: Specification for adaptors" published. The 30 A plug is the largest of the family. [11] The earth pin also serves to operate the basic shutter mechanism used in many sockets. The first of these was stated as, "To ensure the safety of young children it is of considerable importance that the contacts of the socket-outlet should be protected by shutters or other like means, or by the inherent design of the socket-outlet." [57] Rewireable plugs must be designed so that they can be wired in a manner which prevents strain to the earth connection before the line and neutral connection in the event of failure of the cord anchorage. 1 added specification for surface mounted socket-outlets. In 1934, BS 372 Part II was in turn superseded by the first edition of BS 546 Two-Pole and Earthing-Pin Plugs and Socket Outlets. There must be an accessible fuse. The same catalogue included lampholder plugs for both BC and ES lampholders (capacity unspecified), and also a type of two-pole concentric plug and socket (similar to a very large version of the concentric connectors used for laptop PC power connections) in the "1 to 5 lights" and "5 to 10 lights" capacities. The plug and socket replaced the BS 546 plug and socket, which are still found in old installations or in special applications. Waking an Amiga 500 from its slumber - … [65] There is no provision for establishing the interchangeability with any other device having plug pins incorporated, but which is not covered by BS 1363 (for example a charger or socket cover) unless that device conforms precisely to the plug pin dimensions specified. The old cable plug colour codes did not account for proper phase rotation, therefore most of Europe now abides by IEC (International Electrotechnical Commission) wiring colour codes for AC circuits. [27] The introduction of a 13 A fused plug, rated as 3 kW,[91] enabled Scholes to propose their system as a possible solution for the new standard competing with the Dorman & Smith round pin solution, but it was not selected and the completely new BS 1363 design prevailed. When BS 546 was in common use domestically in the UK the standard did not require sockets to be shuttered, although many were. [46] The line and neutral pins have a rectangular cross section 6.4 mm by 4.0 mm, 17.7 mm long and with centres 22.2 mm apart. BS 73 Wall plugs and sockets (five ampere two-pin without earthing connection) was first published in 1915, and revised in 1919 with the addition of 15 A and 30 A sizes. It is sometimes still used to connect lamps to a lighting circuit. September 1995: BS 1363-2:1995 "13 A plugs socket-outlets adaptors and connection units - Part 2: Specification for 13 A switched and unswitched socket-outlets" published. The use of this standard is enforced by consumer protection legislation[100] which requires that most domestic electrical goods sold in Ireland be fitted with an I.S. Lot of vintage new old stock brass fat boy lamp sockets made by Hubbell. Many D&S sockets were still in use until the early 1980s, although the difficulty in obtaining plugs for them after around 1970 often forced their users to replace them with BS 1363 sockets. This plug was used to connect low power appliances (and to adaptors from the larger socket types). The pin configuration of the Tripin appears virtually identical to modern BS 546 plugs. SS 145-2:2010 Specification for 13 A plugs and socket-outlets - Part 2 : 13 A switched and unswitched socket-outlets. Amongst its members was Dame Caroline Haslett, President of the Women's Engineering Society, Director of the Electrical Association for Women and an expert on safety in the home. [citation needed] Line (commonly, but technically incorrectly, called live) carries the full supply voltage relative to the neutral. Around 1979, Post Office Telephones introduced the Plug and Socket (PST) method of connection. BS 1362 specifies sand-filled ceramic-bodied cylindrical fuses, with dimensions of 1 in (25 mm) in length, with two metallic end caps of 1⁄4 in (6.4 mm) diameter and roughly 1⁄5 in (5.1 mm) long.

Prime members enjoy fast & free shipping, unlimited streaming of movies and TV shows with Prime Video and many more exclusive benefits. [27] The Wylex plugs were initially made in three ratings, 5 A, 10 A and 15 A and were unpolarized (the current-carrying pins were on the same centre line as the earth pin). [61] The pressure group PlugSafe[62] reported in March 2014 that since August 2011 "thousands" of listings of products including illegal plugs had been removed from the UK sections of the websites eBay and Amazon Marketplace. As electricity became a common method of operating labour-saving appliances, a safe means of connection to the electric system other than using a light socket was needed. Wired connections may also be connected to the ring, and these are also required to include a suitably rated fuse. A separate standard specifying a switched version of the BS 1363 socket-outlet for use with BS 1363 plugs. This method is sometimes used to allow a Europlug (with two small round pins and no earth pin) to be forced into the open line and neutral ports. Sockets are designed to prevent exposure of bare energised contacts. Some of these are legal in the country they are manufactured in, but do not meet BS 1363 – these can be brought into the UK by unsuspecting travellers, or people purchasing electrical goods online. The longer earth pin ensures that the earth path is connected before the live pins, and remains connected after the live pins are removed. The metric values are conversions provided here for convenience. There is an erroneous tendency to refer to power conversion devices with incorporated plug pins as plugs, but IEC 60050 refers to these as 'direct plug-in equipment' defined as "equipment in which the mains plug forms an integral part of the equipment enclosure so that the equipment is supported by the mains socket-outlet". Counterfeit products are regularly seized when found, to enforce the safety standards and to protect the approval marks and trademarks of imitated manufacturers. [29] Unlike the original, the plug has insulated sleeves on the pins. This arrangement ensures that the dedicated plugs can all plug into an ordinary ("non-dedicated") socket, but that the various dedicated plug and socket combinations are not interchangeable (nor can a non-dedicated plug be inserted into a dedicated socket). Minor changes only. It provides for an overall rating of 250 V AC, minimum current rating of 5 A, and a maximum of 13 A. Adaptors with BS 1363 plug pins must incorporate a BS 1362 fuse. [96], The dedicated versions have specific colours assigned to them, depending on the rotational position of the flattened portion. These sockets are both marked with the Hubbell globe logo. One of these, the Electrical Installations Committee, was charged with the study of all aspects of electrical installations in buildings. An early method of sleeving the pins involving spring-loaded sleeves is described in the 1967 British Patent GB1067870. Comyan Bulb Light Plug Socket Adapter,Polarized Handy Outlet Splitter, E26 The US Standard Screw Light Holder, Two Holes, Easy-to-Install, 6 Pack, White. The protective earth[12] connection allows the exposed metal parts of the appliance to be connected to earth, providing protection to the user should those exposed parts inadvertently come into contact with any live parts within the appliance.

I.S. This contrasts with the radial system (which is also used in the UK, often in the same installation) wherein a single cable runs out radially, like a spoke, from the distribution board to serve a number of sockets. The regulations also contain a provision for the approval of non-BS 1363 conforming plugs when "the plugs are constructed using an alternative method of construction which provides an equivalent level of safety in respect of any risk of death or personal injury to plugs which conform to BS 1363 and is such that plugs of that type may reasonably be expected to be safe in use". 107 sold. "[77], Plug adaptors permit two or more plugs to share one socket-outlet, or allow the use of a plug of different type. This plug is often used for air conditioners and washing machines. (Safety) Regulations 1994 permit domestic appliances fitted with non-BS 1363 plugs to be supplied in the UK with conversion plugs fitted, but not with conversion plugs supplied for fitting by the consumer. BS 1363 plugs have been designated as Type G in the IEC 60083 plugs and sockets standard. Only 3 A and 13 A fuses are specified. BS 546 is also the precursor of current Indian and South African plug standards. PAS 003 allowed for the design and approval of plugs without earthing intended for class II applications only. 11, Electrical Installations, Paragraph 84, Post War Building Studies No. A conversion plug[82] is a special type of plug suitable for the connection of non-BS 1363 type plugs (to a recognized standard) to BS 1363 sockets. The insertion of non-compliant plugs may damage sockets. Because of this, even if a plug is not fully inserted into a socket, touching the exposed part of the prongs can’t give you a shock. Group B2 of the GOST 7396 standard describes BS 1363 plugs and sockets. Changes include the introduction of sleeved pins on Line and Neutral, metric dimensions replacing inches, specifications added for non-rewirable plugs and portable socket-outlets. Both neutral and line carry current and are defined as live parts. Such covers are also sold in the UK, but the shutters of the BS 1363 socket-outlet make these unnecessary. In 1941 Lord Reith, then the minister of Works and Planning, established committees to investigate problems likely to affect the post-war rebuilding of Britain.
