Mumble years ago I requested a 30/32A supply to a test bench. Our
internal power tech did it (in proper steel conduit) using stranded
4mm^2, which he reckoned was much easier to handle in conduit than
solid core.

When metric size cables firsta ppeared on the market they had solid core.
Even 2.5mm was a b****** to pull through conduit. Then the manufacturers
saw sense and provided a stranded version.


I never did investigate what the composition of the stranded wire was
- probably a successor to 7/0.036.

Funny that how 4mm (or 25mm) is made up is never stated - as it was
pre=metrication.
