[IEV number 441-11-01]
A switchboard as defined in the National Electrical Code is a large single panel, frame, or assembly of panels on which are mounted, on the face or back or both switches, overcurrent and other protective devices, buses, and, usually, instruments.
Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
The types of switchboards, classified by basic features of construction, are as follows:
1. Live-front vertical panels
2. Dead-front boards
3. Safety enclosed boards( metal-clad)
[American electricians’ handbook]
The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.
Its definition, design and installation are based on precise rules; there is no place for improvisation.
The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.
It specifies in particular:
> the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;
> the design and verification rules, constituting a benchmark for product certification.
All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.
Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.
A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.
Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.
What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.

Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).
В частности, он определяет:
> распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;
> конструкцию, технические характеристики, виды и методы испытаний НКУ.

Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.
Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.
Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.
Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.
[Перевод Интент]LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.
The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.
In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.
Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.
The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.
[ABB]Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.
Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам
Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.
Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются
Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.

[IEV number 441-11-01]
A switchboard as defined in the National Electrical Code is a large single panel, frame, or assembly of panels on which are mounted, on the face or back or both switches, overcurrent and other protective devices, buses, and, usually, instruments.
Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
The types of switchboards, classified by basic features of construction, are as follows:
1. Live-front vertical panels
2. Dead-front boards
3. Safety enclosed boards( metal-clad)
[American electricians’ handbook]
The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.
Its definition, design and installation are based on precise rules; there is no place for improvisation.
The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.
It specifies in particular:
> the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;
> the design and verification rules, constituting a benchmark for product certification.
All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.
Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.
A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.
Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.
What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.
[Schneider Electric]НКУ играет главную роль в обеспечении электроэнергией, удовлетворяя при этом всем требованиям по безопасности людей и сохранности имущества.
Выбор конструкции, проектирование и монтаж основаны на чётких правилах, не допускающих никакой импровизации.
Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).
В частности, он определяет:
> распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;
> конструкцию, технические характеристики, виды и методы испытаний НКУ.
В стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000) описываются все компоненты НКУ.
Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.
Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.
Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.
Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.
[Перевод Интент]LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.
The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.
In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.
Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.
The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.
[ABB]Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.
Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам
Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.
Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются
Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.

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.
