does the ambiant temp correction factor apply to romex wire in attics?
a recent study book (not a mike holt book) states a 25a load ac unit needs a #6 wire @ 60c with ambiant temp in attic of 122f.
in all my years in residential wiring working for large companys, we always would run it in 10/2.
i asked a friend master electrician about this and he thought i was crazy to suggest a #6 for a 25a ac!
a few months back, a new master electrician working as a city inspector asked me about the ambiant temp of the 14 and 12 guage wires in the attic of a house and i looked at him completly clueless.
