This class presents every significant change made to Chapter 6 in the 2020 National Electrical Code® (NEC-2020). Chapter 6 governs electrical connections to specialized equipment. Since this specialized equipment often sees the greatest innovation and most rapid changes of any in the electrical field, it also sees a host of NEC revisions during every code renewal cycle, including the 2017-2020 code review cycle.
