I did state that my "does not increase at all" was a code matter, on which I would concede on appliance cords but I insist remains the case with romex.
So you have cited a data point opposing my point as well as a data point supporting my point (200C single conductor in free air good for 45 amps).
Sure is true with most wiring, such as permanently installed wiring! Code says 15 amps for AWG 14 regardless of temperature rating for permanently installed wiring!
I google for that and find a nice chart:
But does the Code allow AWG 14 with THNN insulation to be used in permanently installed wiring in a building in circuits protected by fuses or breakers of more than 15 amps? Since I conceded on appliance cords, I still consider the issue of permanently installed wiring to be valid!
Starting to sound like what I am saying, especially in terms of code?
