I have 2x0.5 mm power wire ... how much amp can it safely stand ? (220 V here)
Thanks Yakov
2x0.5 mm power wire -- how much amp ?

0.5 sq. mm?
0.5 sq.mm, yes

Maybe 2 amps then. It's about 20 AWG.
google is your friend.

In the UK (230v) 0.5mm² twin flex is rated at 3 amps.

It's generally the same current rating no matter the voltage.
That's rather a broad statement. ;-)

In reality more like 240V and it's 250V right here.

The USA likes to run cable hotter IIRC.

It's a nominal voltage like all domestic supplies.

It's a straight fib in the case of the UK for reasons of political correctness.

tness.
I'm not sure which figure you mean, nor what you mean by 'straight fit', but I'm not sure the term would sit completely comfortably with either figure.

Not really, although the original 240 wasn't altered. They just changed the allowed spread to harmonise with Europe.

I remember all of those German radios with the multiple voltage primaries. There must have been a lot of different systems then.
Depends a bit on whether you rate the cable for how hot you allow it to get in a specified environment, or as here where the rating of a cable is based on the allowable circuit voltage drop expressed as a percentage of the nominal voltage over a specified length.

Environment is a factor. So is the number of other current carrying cables packed with it.
But the OP gave no other details.
I assumed it is a power cord or flex rather than permanent house wiring by the size, and this type of cable is expected to be exposed?

correctness.
The reasoning is as follows.
The voltage in the UK was 240V. In mainland Europe it was 220V.
In order to 'harmonise' the voltage in the EU a 'political decision' was made to call it 230V and widen the tolerances.
