@ Johannes You wrote: "BTW: the context says "ratings", not "rating", i.e. at least two different ratings..."

Actually, that's not quite (or not necessarily) true — the fact that the source text says 'wires' in the plural is sufficient justification (in EN) for making the 'ratings' plural; there could be different wires, each of which needs to have the correct rating for the job it is doing; hence not necessarily always the same rating.
Johannes Gleim Mar 4, 2015:
I do also worry that the translation would be too narrow to cover all the meanings. In such cases the translator should try to cover all relevant aspects by choosing a term, which does not reduces "ratings" to a simple dimension or to stipulate any requirement, not given in the context. Apparently the editor hands over the responsibility for selecting the right wire or cable to the client, without specifying any property. If the translator specifies "cross-section" explicitly, he is responsible for all misunderstandings, errors, or even injuries, which may be caused by neglecting proper characteristics.

BTW: the context says "ratings", not "rating", i.e. at least two different ratings, whatever they are.
Tony M Mar 4, 2015:
@ Johannes What you say makes sense of course — but there you are going beyond translation and extrapolating into over-interpretation on the basis of your prior knowledge. You are calling into question the logic of the source text (which I agree, on the face of it appears flawed) — but it is not our job as translators to re-write the source text; all Asker could do is to flag it up as a query for the customer.
Johannes Gleim Mar 4, 2015:
Yes It depends on the circumstances, whether sufficient EMC protection is achieved simply by twisting or whether additional shielding must be provided. This must be evaluated by the contractor and is implied in the requirements.

But it is true, that EMC protection cannot be warranted by the cross-section. Electromagnetic interferences depends mostly on current, voltage, frequency and radiating properties of the cable, but not on the cross-section. The cable must be designed accordingly.
Tony M Mar 4, 2015:
@ Johannes If that were the case, then the source text is just plain wrong: one would never properly write 'rating' simply to describe the fact that a cable is screened etc. — that is the form of the cable, and would be one of its 'characteristics'.

Besides, you are assuming it is meant to be screened, but the source text doesn't actually say that — in some circumstances, sufficient EMC protection may be achieved simply by twisting the conductors together, without the need for them to actually be screened.
Johannes Gleim Mar 4, 2015:
The context says "To reduce electromagnetic interference use of wires with adequate ratings and twists". This cannot be achieved by sizing the cross-section or current rating, but by selecting a shielded cable with twisted leads. See

Tony M Mar 4, 2015:
@ Johannes In a general sense, yes; however, in EN, when 'rating' is used alone like this without any qualifier, and depending on the immediate context, 'rating' often in fact implicitly means 'current rating'; were it to be intended to refer to other ratings, or indeed all of them, then they would probably be more likely to write 'suitable characteristics' or 'specifications'.

disagree Johannes Gleim : wire rating consists of properties like ampacity, dielectric withstand, temperature rating. flammability, etc. The cross section is only one one item influencing the current rating. Metal composition and heat dissipation are essential, too.

conducteurs de caractéristiques adéquates

Je pense que "rating" ne se limite pas à la section du conducteur.
En outre, "adequate" se rapporte aussi à "twists"

neutral Tony M : The use of the term 'rating' does very specifically imply 'current rating', which is derived from but not measured by the cross-section; just generally 'caractéristiques' is too woolly.

conducteurs à données limites de courant

http://iate.europa.eu/SearchByQuery.do?method=searchDetail&l...

Les conducteurs en cuivre ou aluminium de même section ne peuvent pas supporter le même courant à cause de conductibilité différent. Cela dépend aussi de l'utilisation des câbles, du service et de la température d'ambiance.

Again, I was unable to provide further references the week ago.

As shown below “wire rating” affects not only the cross-section, but the temperature rating as well as insulation properties like rated voltage, dielectric strength and flammability.

Wire Knowledge
:
A classification for a solid insulation material that can be softened and made to flow by heating, extruded onto wire and quenched in cool water to make solid again. It can readily be softened and re-softened by repeated heating, but remains in a safely usable solid form when operated within its rated temperature limits.

Normal Temperature Rating

Find the ampere rating of the conductor, either by its markings or wire size, in the National Electrical Code, Table 310-16, or applicable localcode.

Re: AWG wires rating AMPS

You must specify insulation rating.
Std. NEC published ratings are for: 60C. 75C. 85C. 90C.Insulation @ 20C. ambient.
For a 70C. ambient you're into some serious derating.
National Electric Code (US) has tables of "ampacity" ratings.
http://cr4.globalspec.com/thread/11636/AWG-wires-rating-AMPS

90 °C is the temperature rating of the fixture. Therefore, it would make sense that the wiring it connects to should have an equal or greater temperature rating.
http://boards.straightdope.com/sdmb/archive/index.php/t-1865...

For example, I can use a 400 amp breaker on 500 Kcm wire, but only when the load calc is less than the wires rating.
http://forums.mikeholt.com/showthread.php?t=166395&page=5

If more the 24” the wires rating are reduced according to table E3605.3
:
The bundled #12AWG romex are no longer rated for 20amps, they are reduced by 20 - 50 percent depending on which section of the bundle I’m looking at (it starts off with 10-15 wires and then some split off and so forth and the bundle gets smaller)
:
For the purposes or derating only, the #12 AWG conductors were rated at 30 amps. So the 20-50% derating leaves you with an amp range or 15-24 amps
:
The allowable ampacity depends not only on the size and composition of the conductor but also on the temperature rating of the insulation. If the insulation can withstand higher temperatures then a higher amperage can be permitted.
http://www.inspectorsjournal.com/forum/topic.asp?TOPIC_ID=11...

This, among other things, shall include checking whether all equipments, fittings, accessories, wire/cables, used in the installation are of adequate rating and quality to meet the requirement of the load.
http://www.dudbc.gov.np/uploads/default/files/555f2944e317ee...

All the internal connections shall be with either solid copper PVC insulated or copper conductor PVC insulated wires of adequate rating.
