Given the thousands upon thousands of miles of copper clad steel
installed, there must be a standardized way to deal with the scratch off
the copper problem. Probably some variant of the Western Union splice.
For what it's worth, on the *thinnest* copper clad (21% IACS), on AWG
12, the cladding is 2.4 mils. That's fairly thick compared to the 81 mil
overall diameter.

I wonder if "copperweld" twin lead is more like the very thin silver
flash on hookup wire to make it solderable? Or that inexpensive fairly
small gauge copper coated speaker wire?f
