Except of making me female, this was good -der- erste aus deutschland
Oops! My apologies. [Linked Image] I shouldn't have made that silly mistake, as I do know the difference betweeen der/die/das.

I'm not sure if my ISP has an incoming limit for attached file sizes, but I've never had any problems receiving 1MB+ attachments, so for our purposes there shouldn't be any difficulties.

C-H:

just looking at that 10 mm2 solid wire makes my hand hurt.
You bet! I can feel my wrists aching just thinking about shaping that. Any bigger and we'd need to use a conduit bender to form the wire into shape! [Linked Image]

In the older British cables (before about 1970) we were at the other extreme. Only the very smallest size (1/.044, almost equivalent to modern 1.0 sq. mm) was solid. Everything else was stranded: 3 strands for the next two sizes and 7 strands for the other common domestic sizes.

By the way, American Romex now has a ground wire the same size as the other conductors, but British "twin & earth" still has the earth one size smaller, e.g. 4mm cable has a 2.5 earth. (The exception being 1.0 cable which has a 1.0 sq. mm earth.)

Which cable system do you mean is flex?
"Flex" is used in British English as a shortening of "flexible cord." It refers to cords with a fine-stranded wire, such as the top and middle cords in your second photo.

On the color code issue, the U.K. had a similar problem when the European colors were adopted for flex, as blue was (and still is) used as a phase in fixed wiring.

We had quite a discussion on color coding a while back:
