On internet, where can I find a table that lists the current,
in ampers, that given flex wire can carry ? Specifically, I'm
interested in amps rating for 2x1.5 sq.mm. and 2x2.5 sq.mm
(220V). I tried to google no luck so far.


As Tim says,there are many ratings for any given cable - see section 4
of
http://www.kevinboone.com/cableselection_web.html.

However for a rule of thumb in domestic installation, cables burried in
plaster or clipped to joists and not covered by insulation 1.0sq is
rated at 15amps, 1.5sq at 20 amps and 2.5 at 27 amps.

Standard radial circuits usually fuse 1.0 at 5 or 6amps ,1.5 at 10 or
15 amps and 2.5 at 20amps. Ring circuits in 2.5 are usually fused at
30amps.

Contrary to Tim's post 1.5sq is a litttle larger than 16swg.
