using http://www.powerstream.com/Wire_Size.htm

is there a functional difference, other factors ie metal purity equal,

between 8-12-14 gauge wire having 10 strands and 25 strands ?



** Yes, stranded wire is far more flexible.


does covering each copper strand with aluminum coating increase
conductivity ?


** Aluminium wire is often coated in copper, not the other way around.

It improves conductivity and most importantly makes it possible to solder the ends.

Sometimes it is passed off as being pure copper to the unwary.

accessed the specs via 4 lines of ID codes.....copper inside, aluminum coating outside, 25 strands Ga 12 has a mil spec rating

difficult scraping the silver off with a new utility blade

More likely to be coated with silver, particularly if mil spec.
