You still haven't addressed the concept of a duty cycle for cables or wires - - - - which was my question.In the electrical design world, the rating of any given wire or cable depends on where you put it.
Cables suspended in free air have a much higher rating than the same cables installed in conduits.
Cables in ductbanks have to be derated depending on how many cables are around the.
Wiring installed on high ambient conditions are derated per a chart.
I had to install an exhaust fan on one large temporary feeder that was on the roof.
I hadn't mentioned anything to do with capacity de-rate based on conditions which is quite a different thing.
(There is the concept of duty cycle on welding machines. The way this concept is used is, imo anyway,
quite different between Europe and North America. But that - - too was not what my question pertained too.)
