This course reviews 25 significant updates made in the 2026 National Electrical Code (NEC). The lesson material focuses on how the updates affect electrical installations, safety procedures, and compliance with state law.
Learning Objectives
By the end of the two hours, you should be able to:
- Identify key new articles, global changes, and code organization updates introduced in the 2026 NEC, including Section 90.3.
- Recognize updated definitions and requirements related to ground-fault circuit interrupters (GFCIs), special-purpose GFCIs (SPGFCIs), and equipment listing and labeling.
- Describe electrical safety requirements related to fault current, short-circuit current ratings, arc-flash hazard marking, and working space.
- Summarize major changes to load calculations, energy management systems, and overcurrent protective device (OCPD) requirements.
- Identify updated installation requirements for receptacles, lighting outlets, conductor sizing allowances, and damaged conductors.
- Recognize key requirements related to wiring devices, panelboard short-circuit ratings, electric vehicle power transfer systems, and emergency system wiring.
IACET CEUs
These courses gives you the opportunity to earn IACET CEUs through our parent company Certus. As an IACET Accredited Provider, Certus offers IACET CEUs for its learning events that comply with the ANSI/IACET Continuing Education and Training Standard. To earn IACET CEUs, you must:
- Complete all lessons in the course,
- Correctly answer every quiz question posed through the course, and
- Complete the course evaluation.
Assessment Information: This online course presents each section with commentary, a graphic illustration or photograph, and requires the learner to answer multiple choice questions after reviewing the content. The learner must complete all multiple-choice questions for each section correctly to get IACET CEUs, a certificate of completion, or state license renewal credit for the course. If the learner's first response is incorrect, learners will be immediately allowed to answer the question again until the correct answer is chosen. Question choices are randomized, so each participant will have a unique testing experience
Prerequisites: This course has no prerequisites.
