State inspectors here enforce along the lines of what you are thinking. The lugs in the panel are NOT ever rated 90°, therefore you cannot use the 90°rating for the final numbers. However you are allowed to use this number before making deduct tons for ambient temperature and box fill. Typically figure 40 amps for #8 copper, bit 30 amps for aluminum. As far as the wire in PVC, it is very hard to find wire that is not dual rated THHN/THWN. When you do find it, it is usually in rated assemblies such as romex. Again the state, subject to local rules, inspectors here say that even of it is in conduit but in a wet location you need to use THWN rated wire. So I cannot run romex from the wall of my house through 2'of seal tite to an air conditioning disconnect, but have to go right into the back of the disconnect or a Junction box. Is responsible see to the voltage drop, a rule of thumb is to step up a wire size for every 100 feet. There are voltage drop calculators on the internet to help find an exact number. In short you can't go wrong figuring everything at the lower temp ratings and maybe consult locall authorities.

I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the
