How do you choose the correct AWG size conductors for a specific demand load. I am in canada using the CEC. Here is the specific question: "A conduit with a total of four ungrounded conductors is installed in an ambient temperature of 50 degrees C. The demand load is 20 amps. T90 Nylon copper conductors are used. What is the minimum trade size conductor required?" Thanks!

Not trying to through this off topic.. Try posting this in the Canadian specific section. Us guys down south of you are illiterate and will fail to see the "Canadian" part of your thread.... LOL..
Now, is this a school question? If so, post what you think the answer is and what code sections gave you that answer. You will get a lot more help by showing you are attempting to work it out yourself.
I dunno i thought the methodology was the same for the most part... How would you go about doing this in the american electrical code? not necessarly looking for the answer, but the process. What i was thinking is:
1. Termination temperature (75 degrees) is used to find conductor.
2. 4 conductor correction factor
3. ambient temperature correction factor
4. find new conductor size
