Covers the changes in the 2026 National Electrical Code for special systems, beginning with health care essential electrical systems in Article 517 and information technology equipment in Article 645 and moving through photovoltaic systems, fire pumps, emergency and legally required standby systems, interconnected power sources in Article 705, limited-energy systems in Articles 720 through 726 and communications systems in Chapter 8.
The course then addresses motors, transformers and high-voltage equipment: listing of high-voltage overcurrent protection in Article 245, cable installation and induced currents in Article 305, reconditioned medium-voltage cables, motor conductor sizing in Article 430, generators, capacitors, storage batteries and the new enclosure, vault and modification requirements for high-voltage equipment in Article 495.
Learning objectives
- Identify changes to health care, information technology, fire pump and emergency system requirements in the 2026 NEC.
- Apply the revised requirements for photovoltaic systems and interconnected power sources in Articles 690 and 705.
- Locate the consolidated limited-energy and communications requirements in Articles 720 through 800.
- Determine conductor sizing, protection and installation requirements for motors, generators, batteries and high-voltage equipment.
