Covers 2026 National Electrical Code changes for special systems, beginning with solar photovoltaic systems in Article 690, including rapid shutdown, PV disconnects, listing, system voltage calculation and labeling, and circuit sizing for bifacial modules. Participants then review interconnected power sources in Article 705, including source connections to a service, source disconnecting means, and ground-fault protection, along with flexible cords for wind turbines.
The course then addresses limited-energy systems in Articles 720 through 723, including underground installation, physical protection, cable support, power sources, cable listing and marking, mixing of cables, and raceways, along with communications, coaxial, network-powered broadband, optical fiber, and fire alarm cables. Later lessons cover primary protection for communication systems in new Article 742, communications and antenna grounding in Article 750, including mobile homes and premises-powered broadband, and communication entry requirements.
Learning objectives
- Identify changes to PV system requirements in Article 690, including rapid shutdown, disconnects, and system voltage calculation and labeling.
- Apply Article 705 requirements for connecting interconnected power sources to a service.
- Select limited-energy and communications cables and raceways using the 2026 installation tables and listing requirements.
- Locate grounding and primary protection requirements for communication and antenna systems in Articles 742 and 750.
