This class presents every significant change to Chapter 7 -Special Conditions, adopted for the 2020 National Electrical Code® (NEC-2020). This is the most varied Chapter in the NEC. It includes the provisions for such special conditions as emergency back-up systems, limited power circuits, and optical fiber cable as well as the rapidly changing Articles on direct current microgrids, interconnected sources of power supply, energy storage, and stand-alone systems.
There are 29 significant changes to this Chapter covered. The class begins with 7 changes to the Articles on Emergency Systems and Optional Standby Systems, including guidance on incorporating alternative power sources. This is followed by 13 changes to Articles 705 & 706, including a complete overhaul of Article 705 on Interconnected Electric Power Production Sources and new maintenance and identification protocols for Energy Storage Systems. The class finishes up with a wide range of wiring systems adapted to special purposes, including a revision of Transfer Switch rules for Critical Operations Power Systems (COPS), updates to Articles 710 on Stand-Alone Systems and DC Microgrids; clarifications on the Use of Class 1, Class 2, and Class 3 Remote-Control Signaling and Power-Limited Circuits, and three changes to Article 770 on OFC: Mechanical Execution of Work, Cable Routing Assemblies and Cable Trays, and Installation in Enclosures shared with energized conductors.
By the end of this class, students will be able to:
- Properly maintain and install critical operations power systems (COPS) as well as emergency electrical power and stand-by systems;
- Navigate the vastly reorganized NEC approach to the growing fields of DC microgrids, interconnected power supply systems, and energy storage systems;
- Apply expanded uses for Stand-Alone Systems; and
- Comply with the latest codes on power-limited cables and optical fiber cables (OFC).
