One of the most common causes of static electricity is the contact between solid objects. Three-phase electric power (abbreviated 3) is a common type of alternating current used in electricity generation, transmission, and distribution. WebStatic electricity is the stationary electric charge which is produced by friction which causes sparks, or the attraction of other small objects such as dust or hair. Non-conforming products must be withdrawn from the Swiss market before the end of 2018.[52]. Brazil, which had been using mostly Europlugs, and NEMA 1-15 and NEMA 5-15 standards, adopted a (non-compliant) variant of IEC 60906-1 as the national standard in 1998 under specification NBR14136 (revised in 2002). WebThe electrical resistance of an object is a measure of its opposition to the flow of electric current.Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes.Electrical resistance shares some conceptual parallels with mechanical friction.The SI unit of electrical resistance is the ohm (), while electrical They are manufactured in various configurations, depending on the country and the region in which they are used, with various ratings. Atoms are tiny, stretching at a max to about 300 picometers long (that's 3x10-10 or 0.0000000003 meters). Extension cords (extension leads) are used for temporary connections when a socket is not within convenient reach of an appliance's power lead. In Russia, an electric stove can often be seen connected with a 25 or 32A connector. WebWater vapor, water vapour or aqueous vapor is the gaseous phase of water.It is one state of water within the hydrosphere.Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice.Water vapor is transparent, like most constituents of the atmosphere. The assigned IEC appliance class is governed by the requirement for earthing or equivalent protection. WebExploring the latest in scientific discoveries from prehistoric life to missions to Mars. 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 National Electrical Contractors Association's National Electrical Installation Standards (NECA 130-2010) recommends that sockets are mounted with the ground hole up so that a falling object makes first contact with the ground pin. [20], In 2020, in response to the COVID-19 pandemic, the company launched "A Free Pair for Healthcare" offering healthcare workers a free pair of their shoes. "Universal" or "multi-standard" sockets are intended to accommodate plugs of various types. For electricity, single units have load-following capability, or four can comprise a 140 MWe power plant. Static Electricity. The line pin is on the left when looking at a socket with the earth pin offset down. Topics 5-8: Forces; Waves; Magnetism and electromagnetism; and Space physics. We apologize for any inconvenience and are here to help you find similar resources. Biomass is plant-based material used as fuel to produce heat or electricity.Examples are wood and wood residues, energy crops, agricultural residues, and waste from industry, farms and households. Right: Plug. 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 3mm, and provided bad contact because they relied on the secondary plug's bisected expanding pins. Stop. The plugs and sockets used in a given area are regulated by local governments. To improve contact with socket parts the Europlug has slightly flexible pins which converge toward their free ends. In Italy, the system was never definitively abandoned. In this section, you will study what happens when charged particles start moving collectively. Though their maker touts their 'ultra-hip Italian styling,' lots of folks find them hideous. "Clean" (low electrical noise) earth for use with computer systems. The portion of instantaneous power that, averaged over a complete cycle of the AC A lightning rod is a rod made mostly of metal that is mounted on the roof of the building and goes into the ground. The two standards were initially adopted because up to the second half of the 20th century in many regions of Italy electricity was supplied by means of two separate consumer connections one for powering illumination and one for other purposes and these generally operated at different voltages, typically 127V single phase and 220V single phase (from 3-phase 380 V) or two phase (from 220 V 3-phase). Big Blue Interactive's Corner Forum is one of the premiere New York Giants fan-run message boards. 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. Plugs are non-interchangeable between current ratings. Under typical atmospheric conditions, water vapor is continuously generated by There is no socket defined to accept only the Europlug. 10A plugs and socket: Pins which are 4mm in diameter, the centres spaced 19mm apart. Some plugs have built-in fuses for safety. Lampholder plugs are rarely fused. Its modern manifestation was invented by Charles Parsons in 1884. 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. WebWe would like to show you a description here but the site wont allow us. The Danish socket will also accept the CEE7/16 Europlug or CEE7/17 Schuko-French hybrid plug. The big difference between the two is that DC is a flow of energy while AC can turn on and off. Thai Industrial Standard (TIS) 166-2547 and its subsequent update TIS 166-2549[53] replaced prior standards which were based on NEMA 1-15 and 5-15, as Thailand uses 220 V electricity. The IEC type J designation refers to SEV1011's type 12 plugs and type 13 sockets. Sales have absolutely slumped since their peak, though like with seemingly everything in crypto theres always somebody declaring it over and done with right before a big spike. Crocs also announced they would open a "global commercial center" with 50 to 75 employees in Boston, Massachusetts, in 2014, for merchandising, marketing and retail functions. Some appliances sold in the Soviet Union had a flat unearthed plug with an additional pass-through socket on the top, allowing a stacked arrangement of plugs. 1.1.8 Required Practical: Investigating Specific Heat Capacity, 1.1.11 Conservation & Dissipation of Energy, 1.1.14 Required Practical: Investigating Insulation, 2.1 Current, Potential Difference & Resistance, 2.1.3 Current, Resistance & Potential Difference, 2.1.4 Required Practical: Investigating Resistance, 2.1.9 Investigating Resistance in Thermistors & LDRs, 2.1.10 Required Practical: Investigating IV Characteristics, 2.2.3 Comparing Series & Parallel Circuits, 3.1 Changes of State & the Particle Model, 3.1.3 Required Practical: Determining Density, 3.2.6 Specific Heat Capacity v Specific Latent Heat, 4.1.2 The Absorption & Emission of EM Radiation, 4.2.11 Hazards of Contamination & Irradiation, 4.2.12 Studies into the Effects of Radiation, 4.3 Hazards & Uses of Radioactive Emissions & of Background Radiation, 5.3.5 Required Practical: Investigating Force & Extension, 5.5 Pressure & Pressure Differences in Fluids, 5.7.3 Required Practical: Investigating Force & Acceleration, 5.8.4 Factors Affecting Thinking Distance & Reaction Time, 6.1.6 Required Practical: Measuring Wave Properties, 6.1.7 Reflection, Absorption & Transmission, 6.1.8 Required Practical: Investigating Reflection & Refraction, 6.1.13 Ultrasound in Medical & Industrial Imaging, 6.2.5 Required Practical: Investigating Infrared Radiation, 7.1 Permanent & Induced Magnetism, Magnetic Forces & Fields, 7.2.1 Magnetic Fields in Wires & Solenoids, 7.3 Induced Potential, Transformers & the National Grid, 7.3.2 Applications of the Generator Effect, 7.3.3 Graphs of Potential Difference in the Coil, 8.1 Solar system, Stability of Orbital Motions & Satellites, This is caused by the imbalance between negative and positive charges in two objects, Static electricity and sparking is produced by rubbing surfaces which causes insulators to become charged by friction, This applies to solids, liquids and gases, However, when the electrons are transferred, one object becomes, This difference in charges leads to a force of. The only country to have officially adopted the standard is South Africa as SANS 164-2.[30][31]. With the use of an electrostatic generator, static electricity can be produced. There is a variation for hospital equipment with a rectangular left pin, which is used for life support equipment. The simplest type, designated CEI23-50 P17/11, has a central round hole flanked by two figure-8 shaped holes, allowing the insertion of CEI23-50 S10 (Italian 10A plug unearthed), CEI23-50 S11 (Italian 10A plug earthed), CEI23-50 S16 (Italian 16A plug unearthed), CEI23-50 S17 (Italian 16A plug earthed) and CEE 7/16 (Europlug). The plug is three wire, earthed, rated at 10A, 250V and used for Class 1 applications; a slightly larger 16A version also exists. Linear means that students will sit all their exams at the end of the The imbalance in the charge is introduced by physical means. "[23] EU countries each have their own regulations and national standards; for example, some require child-resistant shutters, while others do not. The 10A three-pin earthed rear entry plug is designated CEI23-50 S11 (there are also two side-entry versions, SPA11 and SPB11). Firefighters in Russia are battling a huge blaze at one of the largest shopping malls in the country..

The type 11 plug is unearthed, with two 4mm diameter round pins spaced 19mm apart. This is a round plug compatible with CEE7/1, CEE7/3, and CEE7/5 sockets. The result of a build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. When the force increases, at some point maximum static friction is reached. Its SI unit is the watt.. Crocs, Inc. (stylized in all lowercase) is an American footwear company based in Broomfield, Colorado, that manufactures and markets the Crocs brand of foam clogs. Unlike the Europlug, it is rated 6A. It is usually caused by rubbing materials together. Avoid saying the transfer of 'charge' since this is too vague and will not get you full marks. [44][45] Therefore, some North American devices which can be physically plugged into Japanese sockets may not function properly. Tel 289-387-1025, Generate Electricity From Different Sources - Thermal, Nuclear, Renewable Energy, Electricity and Magnetism - Power Explained, Unit of Electricity - Fundamentals Explained. In this section, we will discuss electrons as carriers of charge, but other types of particles can also carry charge. The result of a build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. For electricity, single units have load-following capability, or four can comprise a 140 MWe power plant. In some countries these adaptors are banned and are not available in shops, as they may lead to fires due to overloading them. Under typical atmospheric conditions, water vapor is continuously generated by Our Electrical Training Institute is a leader in electrical training, through public enrolment electrical courses as well as on-line electrical training courses and webinars. Similarly, we consider only linear motion then point B moves with a velocity VL in the forward direction. [78] In Fall 2017, Balenciaga released a 10-centimeter Croc platform as part of its Spring 2018 collection. Our daily life is full of such examples that are related to different types of electricity. Most Israeli, Swiss, Danish and Italian sockets, were designed to accept pins of various diameters, mainly 4.8mm, but also 4.0mm and 4.5mm, and are usually fed by final circuits with either 10 A or 16 A overcurrent protection devices.[24]. 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. Jibbitz are decorations that can be clipped to the ventilation holes in the shoes. Since the early 1990s earthed sockets have been required in all new electric installations in Denmark.

Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Electricity Forum publishes Electricity Today T&D Magazine and Intelligent Power Today Industrial Electrical Magazine. The plug is often designed so that the earth ground contact connects before the energized circuit contacts. The Europlug is not rewirable and must be supplied with a flexible cord. Electrons are rubbed onto the cloth leaving the cloth negatively charged and the rod positively charged, Examples of sparking from touching a door handle or another person, Lightning is caused by the build up of charge in clouds, Answers to exam questions in this topic are mainly looking for the words 'friction' and the transfer of 'electrons'. The letter system first appeared in such guides in 1967 (. The plug and socket are rated 16 A 250 V AC and are intended for use only on systems having nominal voltages between 200 V and 250 V AC The plug pins are 4.5mm in diameter, line and neutral are on centres 19mm apart. [49][50] This was due to the soft shoe material combined with the smaller size of children's feet. The charge remains until it is able to move away by means of an electric current or electrical discharge.Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits [9] On April 14, 2008, during the midst of the financial crisis of 20072008, the stock dropped 30% in after-hours trading after the company issued a press release in which they significantly decreased earnings estimates for the first quarter. After one week, this had created a 1,500 percent increase of sales, according to a spokesperson for Amazon.com. The 10A three-pin earthed socket is designated CEI23-50 P11, and the 10A two-pin unearthed socket is designated CEI23-50 P10. Others subsume one term under the other. Depending on the supply system, one or both current-carrying connections may have significant voltage to earth ground. Thermoplastic plug is rated 6A and 250V. The Swiss standard, also used in Liechtenstein,[47] is SN 441011 (until 2019 SN SEV1011) Plugs and socket-outlets for household and similar purposes. When you rub the balloon with the wool sweater, electrons are transferred from the wool to the rubber because of differences in the attraction of the two materials for electrons. This article is about the usage in domestic and light commercial environments. A socket may be surrounded by a decorative or protective cover[1] which may be integral with the socket. Fax 905-686-1078 [67] In August 2009, First Lady Michelle Obama was spotted wearing Crocs with her daughter. CEE7/7 specifies an earthed hybrid plug that will fit into both the CEE7/3 and CEE7/5 sockets. The most important difference from the Australian plug is that the Argentinian plug is wired with the live and neutral contacts reversed. The type 15 plug has three round pins, of the same dimensions as type 12, plus two smaller flat rectangular pins for two additional power phases. This means that the charge imbalance has to be neutralized. In Iceland, Magic plugs were widely used in homes and businesses alongside Europlug and Schuko installations. 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.). Statistics Explained is an official Eurostat website presenting statistical topics in an easily understandable way. The CEE7/3 socket and CEE7/4 plug are commonly called Schuko, an abbreviation for Schutzkontakt, Protective contact to earth ("Schuko" itself is a registered trademark of a German association established to own the term). Statistics Explained, your guide to European statistics. [12], In December 2013, the hedge fund SAC Capital Advisors disclosed that it held a 5% stake in Crocs, just over a day after The Blackstone Group said it would invest $200 million in a convertible preferred stock offering that would allow the company to replace its CEO and buy back $350 million in stock. For example, high-current equipment can cause a fire when plugged into an extension cord with a current rating lower than necessary. [33][34], Crocs were in the public eye in 2021 with celebrities like Nicki Minaj and Justin Bieber modeling the shoes on social media. China also uses American/Japanese NEMA 115 sockets and plugs for Class-II appliances; a common socket type that also accepts Europlug (type C) is also defined in GB1002. In a filing with the U.S. Securities and Exchange Commission, SAC Capital management said it had accumulated a 5% passive stake in Crocs. It is given as: Rolling friction is defined as the force which resists the motion of a ball or wheel and is the weakest types of friction. Questions in paper 2 may draw on an understanding of energy Sales have absolutely slumped since their peak, though like with seemingly everything in crypto theres always somebody declaring it over and done with right before a big spike. Plugs and power cords have a rated voltage and current assigned to them by the manufacturer. It is not permissible within the UK for the shaver socket to be fitted and used for a higher rated current draw than the 200mA maximum. WebStatistics Explained, your guide to European statistics. The first model produced by Crocs, the Beach, was unveiled in 2001 at the Fort Lauderdale Boat Show in Florida, and the 200 pairs that they had produced were all sold. Use at 125 V is permitted by NBR 14136, which is against the intention of IEC 60906-1. The NEMA 5-20AP variant has blades perpendicular to each other. It is usually caused by rubbing materials together. there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. View all results for thinkgeek. Static electricity exists when there is a build-up of opposite charges on objects separated by an insulator. Because the isolation transformer is of low rating, such outlets are not suitable to operate higher-powered appliances such as hair dryers. The isolation transformer often includes a 115V output accepting two-pin US plugs (Type A). WebFor those of you who couldnt join us on Facebook this week (@spanglerscience), weve been working hard to provide fun and amazing at home experiences to those who have been impacted by the current events. The pins are not sheathed, in contrast to e.g. Today, sockets without switch are allowed, but then it is a requirement that the sockets have a cavity to prevent touching the live pins. Statistics Explained is an official Eurostat website presenting statistical topics in an easily understandable way. Tall buildings, farmhouses, and other structures susceptible to lightning strikes are often equipped with lightning rods. Type 14 single socket (10A), now obsolete. This is because they each have an equal number of positively charged subatomic particles (protons) and negatively charged subatomic particles (electrons). Static electricity refers to an imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body. [20] Also in April the company acquired Tagger International B.V. ("Tagger"), a private limited liability company incorporated under Dutch law that manufactures messenger bags. For Example rub a baloon on a wool and hold it up to the wall. CEE7/17 specifies an unearthed hybrid plug that will fit into both the CEE7/3 and CEE7/5 sockets. Brazil developed a plug resembling IEC 60906-1 as the national standard under specification NBR 14136. non-quantum) field produced by accelerating electric charges. Direct current (DC) is one-directional flow of electric charge.An electrochemical cell is a prime example of DC power. Vimar brand claims to have patented this socket first in 1975[39] with their Bpresa model; however soon other brands started selling similar products, mostly naming them with the generic term presa bipasso (twin-gauge socket) that is now of common use. The result of a build-up of static electricity is that objects may be attracted to each other or may even cause a spark to jump from one to the other. course. The force of rolling friction is defined as the product of the coefficient of rolling friction and the normal force. For electricity, single units have load-following capability, or four can comprise a 140 MWe power plant. We would like to show you a description here but the site wont allow us. Even so, the Magic security system had some success at first because its enhanced safety features appealed to customers; standard connectors of the day were considered not safe enough. WebAn uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. The modern steam turbine was invented in 1884 by Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kilowatts (10.1 hp) of electricity. Type 12 triple socket (10A), now obsolete and no longer sold or installed. The application of electricity to the mining industry is a distinctive area of both mining engineering and electrical engineering. Although it may accept NEMA plugs, the Thai voltage is 220V and thus is electrically incompatible with devices designed only for 110 V. Chinese dual socket accepting both unearthed 2-pin (upper) and earthed 3-pin (lower) plugs. A 2012 appendix to SEV 1011:2009, SN SEV1011:2009/A1:2012 Plugs and socket-outlets for household and similar purposes A1: Multiway and intermediate adaptors, cord sets, cord extension sets, travel adaptors and fixed adaptors[51] defines the requirements applicable to multiway and intermediate adaptors, cord sets, cord extension sets, and travel and fixed adaptors, it covers the electrical safety and user requirements, including the prohibition of stacking (the connection of one adaptor to another). A technical standard may include compatibility of a socket with more than one form of plug. There are three types of rocks on Earth, igneous, metamorphic and sedimentary. The Swiss standard does not require the use of child protective shutters. WebCharged particles are at the basis of all electricity. Approximately twice a month, around new moon and full moon when the Sun, Moon, and Earth form a line (a configuration known as a syzygy), the tidal force due to the Sun reinforces that due to the Moon. This Danish standard plug is described in the Danish Plug Equipment Section 107-2-D1 Standard sheet (SRAF1962/DB 16/87 DN10A-R). It was mentioned earlier that the movement of protons is not possible and the only movement of electric charge seen in static electricity is electrons.

With electricity, current is a measure of the amount of energy transferred over a period of time. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.The electric current flows in a constant direction, distinguishing it from alternating In some designs, polarised plugs cannot be mated with non-polarised sockets. [34] Both are symmetrical, allowing the line and neutral contacts to be inserted in either direction. When used in CEE 7/1 (unearthed) sockets, or "universal adaptors" there is no protection for those plugs. [61] The socket is rectangular, with lateral key pins and indentations to maintain polarisation, and to prevent insertion of a plug with different current ratings. The pre-1989 system has three flat pins in a Y-shape, with line and neutral 19mm (0.75in) apart. The type 15 socket is recessed, and has five openings (three round and two flat rectangular). The imbalance in the charge is introduced by physical means. Some appliances have a switch for selection of voltage. [14] In August 2018, Crocs announced it was closing its last company-operated manufacturing plants in Mexico and Italy. In a power plant, electromagnets spinning inside many coils of copper wire generate vast quantities of current electricity. One way to discharge them is through a circuit and this is exactly what a lightning strike is. Following are the examples of rolling friction: The coefficient of rolling friction is denoted asr. non-quantum) field produced by accelerating electric charges. When the force increases, at some point maximum static friction is reached. This rule does not apply for sockets not intended to be used for domestic appliances, but it is strongly advised to have class I sockets throughout the home.[46]. History. In this configuration, the connection supply is only rated at 200mA. This alternative is seldom used. WebStatic Electricity. Together, the articles make up an encyclopedia of European statistics for everyone, completed by a statistical glossary clarifying all terms used and by numerous links to further information and the latest data and Static electricity is the stationary electric charge which is produced by friction which causes sparks, or the attraction of other small objects such as dust or hair. Thus there are different styles for each season. There are mainly four types of friction: static friction, sliding friction, rolling friction, and fluid friction. One of the most common causes of static electricity is the contact between solid objects. WebWaste-to-energy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source.WtE is a form of energy recovery.Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel Crocs also sent 100,000 pairs of shoes to hospitals to be distributed to staff. The plug is often used in companies, but rarely in private homes. Early versions were not polarised, but most plugs are polarised today via a wider neutral blade. It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics.The electromagnetic field propagates at the speed of light (in fact, this field It is produced by moving electrons and it is measured in amperes. [15], In October 2006, Crocs Inc. purchased Jibbitz, a manufacturer of accessories that snap into the holes in Crocs shoes, for $10 million, or $20 million if Jibbitz met earnings goals.

The recess provided by CEE 7/3 and CEE 7/5 sockets offers protection against touching the live pins of CEE 7/4, CEE 7/6 and CEE 7/7 plugs. [48] The standard defines a hierarchical system of plugs and sockets with two, three and five pins, and 10A or 16A ratings. The type 25 plug has three rectangular pins of the same dimensions as type 23, plus two rectangular pins of the same dimensions as type 15. Static electricity refers to an imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body. Explore Gizmos Explore Gizmos. Instead, the Europlug fits a range of sockets in common use in Europe. Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. This design can accept CEE7/4 (German), CEE7/7 (German/French), CEE7/16, CEE7/17 (Konturenstecker, German/French unearthed), CEI23-50 S10 and CEI23-50 S11 plugs. Japan also uses a grounded plug similar to the North American NEMA 5-15. Atoms are tiny, stretching at a max to about 300 picometers long (that's 3x10-10 or 0.0000000003 meters). Left: early type (porcelain and brass, c. 1930); right: late type (black plastic, c. 1970). [40] It is rated 15A at 125 volts. The NEMA 5-15 plug has two flat parallel blades like NEMA 1-15, and a ground (earth) pin. The adaptors were mostly used for low power appliances (for example, connecting both a table lamp and a radio to a socket). Following are the examples of sliding friction: The coefficient of sliding friction is denoted ass. This channel of conduction is known as lightning. Static electricity is a phenomenon caused by electric charges at rest. SEV 1011 also defines a "Type 2x" series of 16A plugs and sockets. [14] The flat pins measure 6.5 by 1.6mm (0.256 by 0.063in) and are set at 30 to the vertical at a nominal pitch of 13.7mm (0.539in). The sockets will accept "Type 1x" plugs. The Europlug is also used in the Middle East, Africa, South America, and Asia. WebThe modern steam turbine was invented in 1884 by Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kilowatts (10.1 hp) of electricity. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. The difficult environment, the dynamic power loads, the cyclic and mobile Read more. The surface of the material includes some electric charges which combine the static electricity on that material. Crocs repurchased inventory previously sold to Tidal Trade and accordingly recognized a reduction of revenue of approximately $2.1 million. The application of electricity to the mining industry is a distinctive area of both mining engineering and electrical engineering. Almost every appliance sold in Italy nowadays is equipped with CEE7/7 (German/French), CEE7/16 or CEE7/17 plugs, but the standard Italian sockets will not accept the first and the third ones since the pins of the CEE7/7 and CEE7/17 plugs are thicker (4.8mm) than the Italian ones (4mm); besides the pins are not sheathed and forcing them into a linear Italian socket may lead to electric shock. SEV 1011 defines a "Type 1x" series of 10A plugs and sockets. Find out more with BBC Bitesize. Individual subscriptions and access to Questia are no longer available. Unlike the standard BS1363 plugs found in the UK, the earth pin is on a horizontal axis and the live and neutral pins on a vertical axis.
