I have had zero luck with this but several differing opinions We were trying to judge the ampacity of an existing cable, 3 conductors 500KCM in one jacket or cable. This cable is attached to building rafters, about 10 ft between rafters and the cable is surrounded by air above below beside and is indoors near roof no other conductors …
Would this be subject to free air table?
Some think the being as its a cable assembly jacketed with 3 wires no
Others say its in free air so yes.
