Here is the situation; I have a 200 amp breaker box on the north (2 story) side of my home with lots of unused circuits. The 1 story south end of the home is wired through a 4 circuit sub-panel, this is inadequate for today's needs. I want to pull 10 ga wires through an abandoned hvac duct, to add circuits to the one story as that is the shortest path and it runs completely through the 2 story between the floors north and south. An electrician told me I can't use romex because it is not duct rated. I have a couple hundred ft. of 10-3 w/ground direct burial that I used as a temporary to my shop never really buried, just strung across the field. It appears to be still in good shape, just dirty. I'm assuming I can't use non duct rated because I might not be the last person here and someone may actually try to use the duct for a duct. Not that it ever worked, it was a bad idea in the first place, the main hvac unit never had enough umph to push air that far, and before I got here the previous owner had zoned the 2 story with window units, and I upgraded that to PTACs.
