2026 NEC® Changes: Alternative Energy and Limited Energy

1.00 Hr
SKU: JCOM-00154

This course reviews the 2026 NEC® updates for alternative energy and limited energy systems. Participants will learn how to apply new requirements, including rounding fractions of volts or amperes, using engineering for PV voltage and current calculations, and understanding the relocation of PV disconnection requirements to Article 705. The course covers bonding options for movable PV components, maximum fuel cell system voltages, service conductor interconnection options in existing buildings, DC source conductor marking, and overcurrent protective devices suitable for back-feed.

Additionally, the course explores limited energy system requirements, including recently added or deleted articles, the purpose and scope of Article 720, communication outlet requirements in dwelling units, wiring methods in ducts for dust, grease, and other hazardous materials, raceway sharing between limited and non-limited energy cables, Class 4 system requirements, and the coverage of Articles 724 and 800. This course equips participants to implement alternative and limited energy system requirements under the 2026 NEC®.
