Nec 2024 Wire Ampacity Chart. Calculating the right ampacity is critical to safety: This data shows the allowable ampacities of insulated conductors rated 0 to 2000v, for copper conductors, as listed in the nec nfpa 70e table 310.16, used.
Nec 110.40 recognizes that conductors with sizes based on the 90°c ampacity can be used in installations over 600 v. Which wire to choose for 100 amp service?

You can consult the wire ampacity chart from the 1st chapter and see that the most appropriate wire size for 10 amps is 20 awg wire.
