Heavier wire for same current = less wire temp. rise above ambient = longer wire insulation life.

Last summer we had over 100 days over 100 degrees. We were all crying for help. Rolling blackouts were somewhat common last summer. It is not unusual to see AC units running 4-6 hours non stop during the day. I don't know if the local electricians figure continuous or non continuous I've never asked. Practicality would say continuous load in such a harsh environment.

Again, I apologize for hijacking the "oven" thread.

Ac units are considered continuous loads (440.32) however they have different sizing of conductors which you can try to understand by reading 240.4 (g).
