That’s really odd.

Interesting, what do you see then?

Yes, as US uses an voltage of 120 V, the current drawn by a load P is approximately double the current drawn by the same load P in EU with 230 V. Thus, the wires used in Europe only need approximately half the cross section compared to US. However, the insulation of the wires needs to be of higher standard.

That’s exactly what I wrote. mm^2 should be rendered to square millimeters (mm^2 ) by the browser / app.
In my understanding, ‘cross section’ always referrs to an area. The other property would be the diameter which is measured in units of length.

16 AWG – 1.3 mm^2
14 AWG – 2 mm^2
12 AWG – 3.3 mm^2
10 AWG – 5.2 mm^2

For us from the civilised part of the world ;-)

However, as in Europe we have 230 V system, approximately half the cross section, as stated in the table above, is sufficient.

Edit: This is how the above text should be displayed:

The cable specification is usually written onto or molded into the outer insulation, at least in Europe / EU.
