(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.

pulse delayed relay with control signal
time relay in which the time delay starts when applying the power supply and the control signal; the output momentarily switches for an interval to the operate condition after the setting time has elapsed (see Figure 9)
NOTE 1 – Cycling the control signal during the time delay will not retrigger the time delay.
NOTE 2 – Manufacturer should specify if interval is fixed or variable.
[IEV ref 445-01-12]FR
relais à impulsion retardée avec signal de commande, m
relais temporisé dont la temporisation démarre dès l’application de l’alimentation et du signal de commande et dont la sortie passe momentanément à l’état de travail pour un intervalle donné dès que la temporisation est écoulée (voir Figure 9)
NOTE 1 – La répétition du signal de commande pendant le délai peut ne pas réinitialiser la temporisation.
NOTE 2 – Il convient pour le fabricant d’indiquer si la durée de l’intervalle est fixe ou réglable.

114 short-circuit current (related to cells or batteries)
ток короткого замыкания химического источника тока
ток короткого замыкания
Максимальное значение тока разряда химического источника тока при коротком замыкании внешней цепи.
[ ГОСТ 15596-82]
ток короткого замыкания
Максимальный ток, отдаваемый батареей в цепь с минимальным сопротивлением по сравнению с сопротивлением батареи в заданных условиях.
[Инструкция по эксплуатации стационарных свинцово-кислотных аккумуляторных батарей в составе ЭПУ на объектах ВСС России. Москва 1998 г.]EN
short-circuit current (related to cells or batteries)
maximum current which should be delivered by a cell or battery into an external circuit with zero electric resistance, or an external circuit which depresses the cell or battery voltage to approximately zero volt
NOTE – Zero electric resistance is a hypothetical condition and in practice the short-circuit current is the peak current flowing in a circuit of very low resistance compared to the internal resistance of the battery.
[IEV number 482-03-26 ]FR
courant de court-circuit (d’un élément ou d’une batterie), m
courant maximal que pourrait fournir un élément ou une batterie dans un circuit extérieur de résistance électrique nulle, ou un circuit extérieur qui abaisse la tension aux bornes de l’élément ou de la batterie approximativement à zéro volt
NOTE – Une résistance électrique nulle est hypothétique et en pratique, le courant de court-circuit est le courant de crête circulant à travers un circuit de résistance très faible par rapport à la résistance interne de la batterie.
