105 more's the pity
разг.тем хуже, какая жалость, как жальWhen the time drew near for retiring, Mr. Bounderby took a glass of water. ‘Oh, sir!’ said Mrs. Sparsit. ‘Not your sherry, warm, with lemon-peel and nutmeg?’ ‘Why, I have got out of the habit of taking it now, ma'am,’ said Mr. Bounderby. ‘The more's the pity,’ returned Mrs. Sparsit; ‘You are losing all your good old habits.’ (Ch. Dickens, ‘Hard Times’, book II, ch. VIII) — Когда подошло время отхода ко сну, мистер Баундерби выпил стакан воды. - О, сэр! - сказала миссис Спарсит. - А почему не ваш подогретый херес с лимонной коркой и мускатным орехом? - Ах, сударыня, теперь я бросил привычку пить его, - сказал мистер Баундерби. - Приходится только сожалеть об этом, - ответила миссис Спарсит. - Вы теряете все свои добрые старые привычки.
‘Ay, she was a farrantly lass; more's the pity now,’ added Barton, with a sigh. (E. Gaskell, ‘Mary Barton’, ch. I) — - Да, девушка хоть куда, это-то ее и сгубило, - со вздохом сказал Бартон.
He's done nobody any harm but himself and his family - the more's the pity... (G. Eliot, ‘The Mill on the Floss’, book III, ch. VII) — Мой муж никому не причинил зла - только себе да своей семье. Тем хуже для нас...
‘Where was that pencil before it disappeared?’ ‘In my blazer-pocket, in the changing room. But things have gone from lockers, too.’ ‘And our lockers don't lock, more's the pity.’ (P. H. Johnson, ‘The Honours Board’, ch. 23) — - А где был этот карандаш, который исчез? - В кармане моей спортивной куртки, в раздевалке. Но вещи пропадали и из шкафчиков. - К сожалению, наши шкафчики не запираются.

106 take hold
амер.начать действовать, приступить; принять активное участие; начать распространятьсяThe factory system began to take hold in Germany, chiefly in Prussia, in the third and fourth decades of the century. (W. Foster, ‘Outline of the World Trade Union Movement’, ch. 6) — Фабричная система начала распространяться в Германии, главным образом в Пруссии, в третьем и четвертом десятилетиях XIX века.
It is only when the drink takes hold that I get a bit above meself [= myself], and then would do no harm, anyway, I am pretty certain not. (P. White, ‘The Tree of Man’, ch. X) — я делаюсь немного не в себе, только когда выпью и вино начинает действовать. Но и тогда я никому не причиняю вреда. Ей-богу, не причиняю.

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

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.

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.

[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.
