AS I RECALL ????? The conductivity is basically a function of the cross sectional area of the wire and the wire property itself, they use fine stranded especialy in welding cable applications due to its flexibility and vibration problem resistance. Stranded wire conductivity is the sum of all the net cross sectional areas buttttttttttttttt (and what you may have heard) at higher frequencies an electrical property called the "skin effect" causes the majority of current to concentrate around the outer perimiter of the wire i.e. theres much less current flow in the wires center core area, but at low frequency 60 HZ thats not really an issue (again as I recall).
I's recalling this stuff from wayyyyyyyy back in the late sixties at Purdue so NO WARRANTY Ive spept since then and probably slept through it then also lol as RF and skin effect werent my cup o tea
