I guess you can keep posting new threads until someone tells you it's OK if you want..
It's 'Choice', not 'Choise'
Shops often sell the right cable..

Why? Why cannot you buy the correct cable?
Most home installations are wired with multicore cable, with two circuit conductors and a protective conductor.
Do all of the conductors have their own insulation? What colour(s) is the insulation of the cores?
If you were in the UK I would say that you need to get someone else in to do the work - if you are not prepared to get the right cable you are not likely to like many of the things that you will have to do to comply with UK safety laws.
However, I notice that your e-mail address if from Bulgaria - the wiring practices there are likely to be very different and you really need to find someone that can give you guidance for your country.
This is a UK group so you may well get some general advice that helps, but you should base your work on what is normal practice in your country.
A couple of comments:
There is always a choice! I suspect you are sadly lacking in technical knowledge and simply trying to get "someone" to say its ok for you to make a bodge of installing some electrical equipment. Sadly the only ones here who might are in the same group as yourself.
Don't do it. either get the right cable and do the job properly or leave well alone. You seem to have invented a word "ampacity" which only underlines that you do not have enough electrical knowledge to do the job safely.
Leave it alone before you create a problem or worse danger!
Ampacity is a correct term.
Only in countries where you use the NEC rather then BS 7671.
