(continuous) current-carrying capacity
ampacity (US)
maximum value of electric current which can be carried continuously by a conductor, a device or an apparatus, under specified conditions without its steady-state temperature exceeding a specified value
[IEV number 826-11-13]
ampacity
The current in amperes that a conductor can carry continuously under the conditions of use without exceeding its temperature rating.
[National Electrical Cod]FR
courant (permanent) admissible, m
valeur maximale du courant électrique qui peut parcourir en permanence, un conducteur, un dispositif ou un appareil, sans que sa température de régime permanent, dans des conditions données, soit supérieure à la valeur spécifiée
[IEV number 826-11-13]Ampacity, the term is defined as the maximum amount of current a cable can carry before sustaining immediate or progressive deterioration. Also described as current rating or current-carrying capacity, is the RMS electric current which a device can continuously carry while remaining within its temperature rating. The ampacity of a cable depends on:
- its insulation temperature rating;
- conductor electrical properties for current;
- frequency, in the case of alternating currents;
- ability to dissipate heat, which depends on cable geometry and its surroundings;
- ambient temperature.
Electric wires have some resistance, and electric current flowing through them causes voltage drop and power dissipation, which heats the cable. Copper or aluminum can conduct a large amount of current before melting, but long before the conductors melt, their insulation would be damaged by the heat.
The ampacity for a power cable is thus based on physical and electrical properties of the material & construction of the conductor and of its insulation, ambient temperature, and environmental conditions adjacent to the cable. Having a large overall surface area may dissipate heat well if the environment can absorb the heat.
In a long run of cable, different conditions govern, and installation regulations normally specify that the most severe condition along the run governs the cable's rating. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. Derating is necessary for multiple circuits in close proximity. When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.

When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.

17 Boole, George
SUBJECT AREA: Electronics and information technology[br]b. 2 November 1815 Lincoln, Englandd. 8 December 1864 Ballintemple, Coounty Cork, Ireland[br]English mathematician whose development of symbolic logic laid the foundations for the operating principles of modern computers.[br]Boole was the son of a tradesman, from whom he learned the principles of mathematics and optical-component manufacturing. From the early age of 16 he taught in a number of schools in West Yorkshire, and when only 20 he opened his own school in Lincoln. There, at the Mechanical Institute, he avidly read mathematical journals and the works of great mathematicians such as Lagrange, Laplace and Newton and began to tackle a variety of algebraic problems. This led to the publication of a constant stream of original papers in the newly launched Cambridge Mathematical Journal on topics in the fields of algebra and calculus, for which in 1844 he received the Royal Society Medal.In 1847 he wrote The Mathematical Analysis of Logic, which applied algebraic symbolism to logical forms, whereby the presence or absence of properties could be represented by binary states and combined, just like normal algebraic equations, to derive logical statements about a series of operations. This laid the foundations for the binary logic used in modern computers, which, being based on binary on-off devices, greatly depend on the use of such operations as "and", "nand" ("not and"), "or" and "nor" ("not or"), etc. Although he lacked any formal degree, this revolutionary work led to his appointment in 1849 to the Chair of Mathematics at Queen's College, Cork, where he continued his work on logic and also produce treatises on differential equations and the calculus of finite differences.[br]Principal Honours and DistinctionsRoyal Society Medal 1844. FRS 1857.BibliographyBoole's major contributions to logic available in republished form include George Boole: Investigation of the Laws of Thought, Dover Publications; George Boole: Laws of Thought, Open Court, and George Boole: Studies in Logic \& Probability, Open Court.1872, A Treatise on Differential Equations.Further ReadingW.Kneale, 1948, "Boole and the revival of logic", Mind 57:149.G.C.Smith (ed.), 1982, George Boole \& Augustus de Morgan.

18 Corliss, George Henry
SUBJECT AREA: Steam and internal combustion engines[br]b. 2 June 1817 Easton, Washington City, New York, USAd. 21 February 1888 USA[br]American inventor of a cut-off mechanism linked to the governor which revolutionized the operation of steam engines.[br]Corliss's father was a physician and surgeon. The son was educated at Greenwich, New York, but while he showed an aptitude for mathematics and mechanics he first of all became a storekeeper and then clerk, bookkeeper, salesperson and official measurer and inspector of the cloth produced at W.Mowbray \& Son. He went to the Castleton Academy, Vermont, for three years and at the age of 21 returned to a store of his own in Greenwich. Complaints about stitching in the boots he sold led him to patent a sewing machine. He approached Fairbanks, Bancroft \& Co., Providence, Rhode Island, machine and steam engine builders, about producing his machine, but they agreed to take him on as a draughtsman providing he abandoned it. Corliss moved to Providence with his family and soon revolutionized the design and construction of steam engines. Although he started working out ideas for his engine in 1846 and completed one in 1848 for the Providence Dyeing, Bleaching and Calendering Company, it was not until March 1849 that he obtained a patent. By that time he had joined John Barstow and E.J.Nightingale to form a new company, Corliss Nightingale \& Co., to build his design of steam-engines. He used paired valves, two inlet and two exhaust, placed on opposite sides of the cylinder, which gave good thermal properties in the flow of steam. His wrist-plate operating mechanism gave quick opening and his trip mechanism allowed the governor to regulate the closure of the inlet valve, giving maximum expansion for any load. It has been claimed that Corliss should rank equally with James Watt in the development of the steam-engine. The new company bought land in Providence for a factory which was completed in 1856 when the Corliss Engine Company was incorporated. Corliss directed the business activities as well as technical improvements. He took out further patents modifying his valve gear in 1851, 1852, 1859, 1867, 1875, 1880. The business grew until well over 1,000 workers were employed. The cylindrical oscillating valve normally associated with the Corliss engine did not make its appearance until 1850 and was included in the 1859 patent. The impressive beam engine designed for the 1876 Centennial Exhibition by E. Reynolds was the product of Corliss's works. Corliss also patented gear-cutting machines, boilers, condensing apparatus and a pumping engine for waterworks. While having little interest in politics, he represented North Providence in the General Assembly of Rhode Island between 1868 and 1870.[br]Further ReadingMany obituaries appeared in engineering journals at the time of his death.

19 Gibson, R.O.
[br]fl. 1920s–30s[br]English chemist who, with E.O.Fawcett, discovered polythene.[br]Dr Gibson's work towards the discovery of polythene had its origin in a visit in 1925 to Dr A. Michels of Amsterdam University; the latter had made major advances in techniques for studying chemical reactions at very high pressures. After working with Michels for a time, in 1926 Gibson joined Brunner Mond, one of the companies that went on to form the chemical giant Imperial Chemical Industries (ICI). The company supported research into fundamental chemical research that had no immediate commercial application, including the field being cultivated by Michels and Gibson. In 1933 Gibson was joined by another ICI chemist, E.O.Fawcett, who had worked with W.H. Carothers in the USA on polymer chemistry. They were asked to study the effects of high pressure on various reaction systems, including a mixture of benzaldehyde and ethylene. Gibson's notebook for 27 March that year records that after a loss of pressure during which the benzaldehyde was blown out of the reaction tube, a waxy solid was observed in the tube. This is generally recognized as the first recorded observation of polythene. By the following June they had shown that the white, waxy solid was a fairly high molecular weight polymer of ethylene formed at a temperature of 443°K and a pressure of 2,000 bar. However, only small amounts of the material were produced and its significance was not immediately recognized. It was not until two years later that W.P.Perrin and others, also ICI chemists, restarted work on the polymer. They showed that it could be moulded, drawn into threads and cast into tough films. It was a good electrical insulator and almost inert chemically. A British patent for producing polythene was taken out in 1936, and after further development work a production plant began operating in September 1939, just as the Second World War was breaking out. Polythene had arrived in time to make a major contribution to the war effort, for it had the insulating properties required for newly developing work on radar. When peacetime uses became possible, polythene production surged ahead and became the major industry it is today, with a myriad uses in industry and in everyday life.[br]Bibliography1964, The Discovery of Polythene, Royal Institute of Chemistry Lecture Series 1, London.LRD -
