This table is meant for 75 deg C, is this the ambient temp of the conductors or the insulation of the cable? I thought it was ambient temp of the conductor but this is weird because the ampacity tables in Chapter 3 are based on 30 deg C ambient temp, then you can derate if you need to, so if this is the case why not put Table 9 on a 30 deg C base and then recalculate for different temps from there with the equation they give you.
Thanks for the help and insight
