It governs situations requiring special electrical precautions due to hazardous substances, critical services being provided, or higher risks to the public and other users. This class presents 30 significant changes to Chapter 5, including revised codes on Isolated Ground Receptacles, GFP, Battery Systems, and the Life Safety and Critical Branches of Healthcare Facilities. The class concludes by reviewing changes made to Chapter 6 through Article 620. This part of this Chapter includes some of the most specialized types of equipment to be found in Chapter 6 related to elevators, electric signs, and wiring for office cubicles.
