2024 Nec Ampacity Chart. The wire gauge contains more information. Figure b.310.15(b)(2)(1) interpolation chart for cables in a duct bank.
Nfpa 70, national electrical code (nec), provides guidelines and tables to help professionals select the appropriate conductor size and ampacity for various. 1st nec 210.16 table includes copper wire ampacities from 18 awg to 2000 kcmil for all 3 temperatures.
(3) Conductors With Higher Temperature Ratings If The Equipment Is Listed And Identified For Use With Such Conductors.
Ampacity based on nec ® table 310.15(b)(16) (formerly table 310.16) allowable ampacities of insulated conductors rated up to and including 2000 volts, 60° through.
With Restructuring That Occurred In The 2011 Nec ®, Table 310.16 Was Retitled “Table 310.15 (B) (16)”.
