  • throughout the Code, the word "allowable" has been removed from "allowable ampacities";
  • in Section 0, voltage definitions for dc circuit voltages have been revised;
  • in Section 2, there are new requirements for reducing arc fault clearing times and clarifications on the use of ingress protection designations for enclosures;
  • in Section 4, there is now recognition for conductors sized in mm2 and Table D18 has been added in support of this;
  • in Section 8, load calculations for installations with electric vehicle supply equipment have been revised, Table 38 has been deleted, and voltage drop calculations using Table D3 have been updated;
  • in Section 12, sag and span requirements for overhead installations have been updated, and there are new Rules for non-metallic jacketed cable;
