If I had to guess as to why older wire is thicker than new wire with
the same gauge rating it might be more of a quality control issue than
anything else. I bet the manufacturing process today is more accurate.


Today's process probably HAS to be more accurate. Heard a science thing last
week on the radio. In this country, there is now more copper installed in
houses than there is in the ground.
