For comparison -- A piece of American 12-2 w/ground Romex and a piece of British 6242Y 2.5 sq. mm. T&E (with reduced-size ground wire):

The "Twin & Earth" cable looks closer to UF cable IMO.

T & E cable would make good switch legs here in the US, no re-identifing the white. LOL

Could you legally use the British "romex" in the USA? If it's listed or approved by the revalent British agnecy, is that good enough, or does the NEC require that the agency be an American outfit?

I'd love to have some of that wire for DC circuits and switch loops! I have a feeling that the reduced GEC would be an issue. Is it available with a full-sized earth?

Yes, it looks like UF. Are all y'all (that's plural for "y'all") aware that the Klein NM strippers also work very well on UF?

I'm amazed that they both have solid earths. I don't think we have ever used solid earths in Australia. Stranded is much less likely to snap off at terminations. Stranded conductors are pretty much the norm here for everything except domestic light circuits. Much easier to work with and less likely to break.
If you use single insulated wires in conduit runs are they solid too? That's when you really notice how much easier stranded is to use.

We use solid up to 10 AWG (40 amp capacity if that helps on the size)

All our NM 10 AWG and smaller is solid.

Snapping is not a problem and I like to work with solid.

Cables 'push' a lot farther when solid than when stranded.

The T&E's conductors appears to be slightly smaller in diameter than the #12s. But still larger than #14. Like a #13

Is the ampacity between 15-20 Amps?

Yes but pulling is a lot easier with stranded.

What I'd like to know from you guys over the pond is why do you have all that "paper" stuffed into your cables? I have seen it many times and wondered.

In answer to the ampacity of 2.5mm T&E, it is rated at around 20Amps. The actual current depends on the conditions it is installed under e.g. in thermal insulation or in free air.
