*The NEC allows rounding up to the next standard fuse size from the cable rating, i.e. 150-amp cable size rounds up to a standard 175-amp size.

The term "free air" is defined by the NEC as cabling that is not enclosed in conduit or a raceway. Cables enclosed in raceways or conduits have substantially lower continuous current carrying ability due to heating factors.
