plug To prevent conductor damage, always grasp the power cord by its plug when disconnecting it. In Europe for example, they are called double or triple adaptors, and transform one socket into a multiple socket. They are manufactured in various configurations, depending on the country and the region in which they are used, with various ratings. [citation needed]. These may include plugs with insulated sleeves, recessed sockets, or automatic shutters to block socket apertures when a plug is removed. Japanese plugs generally fit into most North American sockets without modification, but polarised North American plugs may require adaptors or replacement non-polarised plugs to connect to older Japanese sockets. Europlugs are also in common use in Italy; they are standardized under CEI 23-34 S 1 for use with the 10 A socket and can be found fitted to Class II appliances with low current requirement (less than 2.5 A). So called power splitters with this connector as a 3 phase inlet and 3 groups of single phase outputs with individual circuit breakers are generally used to achieve this, and allow load balancing across the phases, important on generator supplies. • Do not modify power cord length or share the outlet with other appliances as it may cause electric shock or fi re due to overheating. Plug can only be inserted one way with French CEE 7/5, but lack of wiring convention means that the system is not polarised. Alternative I is a round plug with cutouts to make it compatible with CEE 7/3 and CEE 7/5 sockets. This alternative is seldom used. Similar configurations are used for outdoor exhibitions, festivals and large events. Where a "neutral" conductor exists in supply wiring, polarisation of the plug can improve safety by preserving the distinction in the equipment. The letter system first appeared in such guides in 1967 (. To reduce the risk of injury from electrical shock, do not open any enclosed area marked with this symbol. The International Electrotechnical Commission (IEC) maintains a guide with letter designations for generally compatible types of plugs,[11] which expands on earlier guides published by the United States Department of Commerce. Standard plugs and sockets based on two round pins with centres spaced at 19 mm are in use in Europe, most of which are listed in IEC/TR 60083 "Plugs and socket-outlets for domestic and similar general use standardized in member countries of IEC". As part of China's commitment for entry into the WTO, the new CPCS (Compulsory Product Certification System) has been introduced, and compliant Chinese plugs have been awarded the CCC Mark by this system. Sockets for electric clothes dryers, electric ovens, and air conditioners with higher current rating. •Otherwise, it may cause a fire or electrical shock. The socket accepts Europlugs and CEE 7/17 plugs. Found inside – Page 308You can zap a component with static electricity by touching the outside of an ... that is plugged into the wall socket and then shut the power strip off. Moulded rubber Soviet plugs cut with knife so that they can fit into CEE 7/3 socket. Instead, the Europlug fits a range of sockets in common use in Europe. In 1989 the standard was revised, with three round 4.5 mm (0.177 in) pins in the same locations designed to allow the socket to accept both older and newer Israeli plugs, and also non-earthed Europlugs (often used in Israel for equipment which does not need to be earthed and does not use more current than the Europlug is rated for). The Danish socket will also accept the CEE 7/16 Europlug or CEE 7/17 Schuko-French hybrid plug. The Thai plug is designated as "Type O" at IEC World Plugs.[11][53][54][55][56][57]. Few private houses in Brazil have an earthed supply, so even if a three-pin socket is present it is not safe to assume that all three terminals are actually connected. The two styles are not intermatable, to prevent a potential floating neutral. The unearthed type 21 plug has two rectangular pins, with centres 19 mm apart. A popular model of this socket type is marketed under the brand name MK Commando[9] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets. When plugging this product into a wall socket, make sure that the electrical socket is not damaged, and that there is no gas leakage. A typical use is for appliances that exceed the 2.5 A rating of CEE 7/16 europlugs. Series II preferred current ratings (in Amps) are: 20, 30, 60, 100, 200, 300, 350, 500 and 600, with wire gauges specified as AWG and circular mil. The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A plug is the movable connector attached to an electrically operated device, and the socket is fixed on equipment or a building structure and connected to an energised electrical circuit. The collar prevents accidental contact with the non sheathed pins when inserting or removing the plug in a recessed socket. A special socket, with an isolation transformer, may allow electric razors to be used near a sink. The fittings are popular in open-air conditions, as they include IP44 weather-proofing. The colour of the housing indicates the type of power available.

In Japan the voltage is 100 V, and the frequency is either 50 Hz (East Japan) or 60 Hz (West Japan) depending on whether the customer is located on the Osaka or Tokyo grid. The type 11 plug is unearthed, with two 4 mm diameter round pins spaced 19 mm apart. aes. The usual Soviet apartment of the 1960s had very few sockets, so this design was very useful, but somewhat unsafe; the brass cylinders of the secondary socket were uncovered at the ends (to allow them to be unscrewed easily), recessed by only 3 mm, and provided bad contact because they relied on the secondary plug's bisected expanding pins. They provide no ground connection but will fit a grounding NEMA 5-15 receptacle. In many areas,[where?] Lampholder plugs are rarely fused. Found insideElectric shock The effect of an electric shock can vary from a slight tingling sensation to death. The severity of the shock depends on the size of the ... Alternative II, popularly known as the Europlug, is a flat 2.5 A-rated plug defined by Cenelec standard EN 50075 and national equivalents. CEE 7/3 sockets were not permitted until 15 November 2011. The 16 A two-pin unearthed plug is designated CEI 23-50 S 16. Some plugs have female contacts that are used only for an earth ground connection. Some older installations have sockets that are limited to either the 10 A or the 16 A style plug, requiring the use of an adaptor if the other gauge needs to be connected. Different voltage and frequency combinations are distinguished by the location of the earth pin (or a plastic projection called the minor keyway, for connectors with no earth pin), as shown in the following table. [58] In the 1960s they were used for 240 V DC in the Power laboratory of the Electrical Engineering department of what was then University College, Cardiff. Do not disconnect power supply by pulling or jerking the cord from the outlet. [15] The current version is AS/NZS 3112:2011, Approval and test specification – Plugs and socket-outlets. [16] The NBR 14136 standard has two versions, neither of which has pin dimensions or ratings complying with IEC 60906-1. They were also used in the Ministry of Defence Main Building on circuits powered from the standby generators to stop staff from plugging in unauthorised devices. The CEI 23-50 P 40 socket, which is quickly becoming the standard in Italy along with CEI 23-50 P 17/11, accepts CEE 7/4, CEE 7/7, CEE 7/16, CEE 7/17, CEI 23-50 S 10, CEI 23-50 S 11, CEI 23-50 S 16 and CEI 23-50 S 17 plugs; its drawback is that it does not accept SPA 11, SPB 11, SPA 17 and SPB 17 side-entry plugs; however almost no appliance is sold with these types, which are mainly used to replace existing plugs. This allows connecting more than one electrical consumer item to one single socket and is mainly used for low power devices (TV sets, table lamps, computers, etc.). Some early unearthed plug and socket types were revised to include an earthing pin or phased out in favour of earthed types. ASUS Prime series is expertly engineered to unleash the full potential of AMD and Intel processors. In Australia these piggy-back plugs are now available only on pre-made extension leads. Three 6 mm pins 20.5 mm long are equally spaced around a 15.4 mm diameter circle. It has a round body like the European CEE 7/2 or flat body with a round base like CEE 7/17. Unlike the standard BS 1363 plugs found in the UK, the earth pin is on a horizontal axis and the live and neutral pins on a vertical axis. [22] CEE 7 consists of general specifications and standard sheets for specific connectors. The standard defines connectors with 3, 4 and 5 pins, but a non-standard variant with 7 pins (6 in a circle plus one in the centre) is commercially available;[4] this can be used for star-delta starting of three-phase motors. [21] The plug has insulated sleeves on the pins. ;�����c �t*��+�%��}|���:B�l&)��4���I�̧!^g���l�� �6��e�`�x((G\9JJ3ي2M��d�m(�d[J����a��'싯� Ƙ�l�Nnjq�;m®��٤�g����uK���g�C�:�"�F�_vLI:�����>�q� as����ȯ����لM���*��a�K3e��T:�\�uȆ����oo�&�����ZP�4�!�W�eӮ}E�)�RƳi�?��E*c����Ħ�>��F�|0��N�y�(�e����uW~�ʶ�Õo�'��!^c}�!�M�>G�i�B�}��^�Uw-gJ �v�R��v,]� �sm?n��. At regular intervals, be sure to pull out the power plug, and using a dry cloth, In the United States it is not usually used for three phase power but for the high leg delta wiring of split-phase electric power (unknown in Europe). 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. Found insideElectricity if you look at lightning on a stormy night, what you will see are the effects of electricity. if you plug a poorly wired appliance into a socket ...

The various positions are referenced from the view of the open side of a socket; the 6 o'clock (6h, 180°) position is at the same angle as the major keyway, and is oriented downwards. (This is the same body that produced the "CEE 7" series of domestic AC plugs.) The simplest type, designated CEI 23-50 P 17/11, has a central round hole flanked by two figure-8 shaped holes, allowing the insertion of CEI 23-50 S 10 (Italian 10 A plug unearthed), CEI 23-50 S 11 (Italian 10 A plug earthed), CEI 23-50 S 16 (Italian 16 A plug unearthed), CEI 23-50 S 17 (Italian 16 A plug earthed) and CEE 7/16 (Europlug). This is often the slot closest to the CPU but may be the second or third slot. There is a big battery to help the engine get started. Always plug into a grounded outlet. An earthed Thai socket that appears to comply with figure 4 of TIS 166-2549. Depending on the supply system, one or both current-carrying connections may have significant voltage to earth ground. Found inside – Page 6Televisions and microwaves plug into a from the wall socket , down the cable , and into ... Lightning is a type of electricity called static electricity . These are a hazard for children who may stick something into the outlet and inadvertently shock themselves. To reduce the risk of electric shock or damage to your equipment: - Do not disable the power cord grounding plug. It is used to switch off the load. alpha – Adds an alpha channel to video - uniform or via chroma-keying . Their installation in new homes was still quite common even in the late 1980s. When used in CEE 7/1 (unearthed) sockets, or "universal adaptors" there is no protection for those plugs. Amazon.com: USB Power Strip Flat Plug, AUOPRO 12 Outlet Surge Protector with 4 USB, Grounded Desktop Extension Cord , 1050J, Dual Switch, Wall Mountable, 9.8 ft Long Cable for Computer Garage Workshop Home Office : Electronics The requirement for insulated pins was introduced in the 2004 revision. hެUO9�*������]KR��D��D�J!7q��mv�]ӣ��fƤ -\ﴲ��f���BƙЖ�B@�3��/���w��q2`R:��ր��p9Ni0��$w�6�I!�m`[){�. Older sockets are so shallow that it is possible to accidentally touch the live pins of a plug. Again, the three-phase power socket is compatible with single-phase plugs, either of 10 A or 16 A ratings:[48]. Center: Socket. This Soviet plug, still sometimes used in the region, has pin dimensions and spacing equal to the Europlug, but lacks the insulation sleeves. Both Thai and Chinese dual sockets also physically accept plugs normally fitted to 120 V appliances (e.g. CE marking is neither applicable nor permitted on plugs and sockets. Replace broken 3-prong plugs and make sure the third prong is properly grounded. Earlier type 11 & 12 plugs had line and neutral pins without sleeved pins, which present a shock hazard when partially inserted into non-recessed sockets. Chinese dual socket accepting both unearthed 2-pin (upper) and earthed 3-pin (lower) plugs. For example, high-current equipment can cause a fire when plugged into an extension cord with a current rating lower than necessary. There are two variants. The plug has two round pins measuring 4.8 by 19 mm (0.189 by 0.748 in), spaced 19 mm (0.748 in) apart and with an aperture for the socket's projecting earth pin. The actual rating of non-rewirable plugs is marked according to the fuse fitted by the cord set manufacturer, the fuse rating being determined by the rating of the flexible cable. The shape of the plugs generally makes it difficult to touch the pins when connecting/disconnecting. 9. Harvey Hubbell patented a parallel blade plug in 1913, where the blades were equal width (U.S. Patent 1,064,833). Sometimes the cords used to plug in dual voltage 120 V / 240 V equipment are rated only for 125 V, so care must be taken by travellers to use only cords with an appropriate voltage rating. The 10 A three-pin earthed rear entry plug is designated CEI 23-50 S 11 (there are also two side-entry versions, SPA 11 and SPB 11). Found insideThese projects are fun to build and fun to use Make lights dance to music, play with radio remote control, or build your own metal detector Who says the Science Fair has to end? If you love building gadgets, this book belongs on your radar. The devices are named using the format NEMA n-mmX, where n is an identifier for the configuration of pins and blades, mm is the maximum current rating, and X is either P for plug or R for receptacle. The primary distinction is by rated operating voltage, as follows: In addition to the colour code, connectors are keyed in one of 12 positions to ensure that incompatible utilization voltages cannot be connected. The isolation transformer often includes a 115 V output accepting two-pin US plugs (Type A). This plug is also commonly used in Chile and Uruguay. As early as 1885 a two-pin plug and wall socket format was available on the British market. Unlike the Europlug, it is rated 6 A. Wiring systems where both circuit conductors have a significant potential with respect to earth, do not benefit from polarised plugs. There are two versions: an older one with flat pins, and a newer one with round pins.[31]. Type 12 triple socket (10 A), now obsolete and no longer sold or installed. Since the early 1990s earthed sockets have been required in all new electric installations in Denmark. Plugs and power cords have a rated voltage and current assigned to them by the manufacturer. %%EOF In Russia an electric stove can often be seen connected with a 25 to 32 A connector. Some plugs have built-in fuses for safety. Older sockets need not be earthed, but all sockets, including old installations, must be protected by earth-fault interrupters (HFI or HPFI in Danish) by 1 July 2008. Since these two modes do not need three phases there is also a dark yellow-orange four-pin connector available designed for a single-phase 110–120 or 220–240 volt load. Italian plugs and sockets are defined by the standard CEI 23-50 which superseded CEI 23-16. Universal sockets may not meet technical standards for durability, plug retention force, temperature rise of components, or other performance requirements, as they are outside the scope of national and international technical standards. adpcmenc – Encode ADPCM audio . Not all installations distinguish the line (phase) and neutral conductors, and reverse wired sockets are not uncommon, so double pole breaking RCDs and main switches are recommended. A voltage converter is required for electrical compatibility in places with a different voltage than the device is designed for.

Shutters over the line and neutral pins are mandatory. In modern installations in Italy (and in other countries where Type L plugs are used) it is usual to find sockets that can accept more than one standard. Although many of our clothes are rated to shield EMF's* by 90%, 99%, or even 99.99%, it would be incorrect for us to round this number to 100%. Use at 125 V is permitted by NBR 14136, which is against the intention of IEC 60906-1. Adaptors are standardized in Italy under CEI 23-57 which can be used to connect CEE 7/7 and CEE 7/17 and plugs to linear CEI 23-50 sockets. shock.
