4-006(1) says: "Where equipment is marked with a maximum conductor termination temperature, the maximum allowable ampacity of the conductor shall be based on the corresponding temperature column from Tables 1, 2 ,3, or 4." Does this refer only to the ampacity inside the enclosure containing the equipment or does it mean that derating is based on the lower temperature? For example, a conduit might contain more than 3 conductors or it might pass through a high ambient area.
