Cite that.

Yes, please.....
Stranded has been used in conduit for years. Unless this changed
recently, this is not correct....

I've come across some wire that is probably 30 years old and is marked
14 gauge. The minimum gauge I want snaking around the house is 12
gauge, so I was about to pull it out when I noticed that the copper is
about as thick as new 12 gauge (and thicker than new 14 gauge). Is the
copper thinner now because of improvements in the manufacturing
process, or something? Is the wire rated by thickness or by current
carrying capacity? If it is current carrying capacity, then are they
using thinner wire because newer copper is a better conductor? This
isn't the plastic insulation I'm talking about, it's about the copper
itself.

I'm still waiting for some measurements. It's amazing how these
threads get lost in other discussions....

I always think the newer wire is thinner too, but legally is should be
the same.

Old 14 gauge strips with a 12 gauge notch on my wire stripper. the newest
batch of 14 gauge is too thin to strip well with my stripper. Visually, the
old 12 gauge is like modern 10, old 14 is like modern 12. As the price of
copper goes up, the wire gets thinner. It seems like it may be a more brittle
or stiffer alloy in the modern wire. Not sure if the alloy allows more current
or if we are being cheated.

The insulation on old type TW wire was thicker than THHN but the wire
is the same.

The wire itself is the same size. The insulation is significantly
thinner. The wire HAS to be the same size unless it is counterfit
Chinese crap.
