Thank you Greg. Good find on the SE cable listing.
I had considered that the cables must have had this rule applied already, but now that I have thought this through a bit more, it appears that since Table 250.122 is based on overcurrent, not wire size, it wouldn’t have any relevance when over sizing conductors for things such as voltage drop calcs, being that the actual overcurrent protection would normally be lower than the maximum rating of the conductor.
Unfortunately, sometimes I’m not the sharpest tool in the shed.
