Votes to reclassify question as PRO/non-PRO:

Non-PRO (2): GILLES MEUNIER, Erzsébet Czopyk

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

The exponent in 2.5² is misleading, and of course refers to the cross sectional area in mm^2. See http://www.signalandpower.com/Harmonized-Europe-Bulk-Power-C... for example.

3G 2.5 mm² cable

It means this is a 3-core cable, and the cores are individually insulated, with a cross-sectional area of 2.5 mm² (which defines the current-carrying capacity — the heavier-guage 2.5 mm² cable is conventionally used in domestic electricity for power circuits up to about 16 A)

Note that as Anton correctly says, the conventional use of the 3 cores in this cable is for live (phase, line), neutral + protective earth.

As Chriss C. points out in his discussion post, the source text is really not strictly accurate here: it is commonly described as "3G 2.5", and everyone takes it as understood that the '2.5' means '2.5 mm²' — but it is NOT correct to add the ² on the end of the 2.5 without the 'mm' that belong with it.

Merci, Daryo !
agree rokotas : I especially stress the point on the last remark of Tony M that if the subscript '2' is kept, it should definitely be written after 'mm'
