National Electrical Code (NEC) Overview


The National Electrical Code® (NEC) — also known as NFPA 70 — is the most widely adopted set of electrical safety standards in the United States, governing the safe installation of electrical wiring and equipment. It’s published by the National Fire Protection Association (NFPA) and recognized as an American National Standard (ANSI/NFPA 70). Although the NEC itself is not federal law, it’s commonly enforced by state and local jurisdictions through adoption into electrical licensing and inspection requirements. Because the NEC is updated on a three-year cycle, electrical safety practices, equipment requirements, and installation guidelines evolve constantly. Staying up to date isn’t just recommended — it’s crucial for legal compliance, workplace safety, and risk management.

Deliver Current & Accurate Code Knowledge

Your learners get the latest code understanding as jurisdictions adopt new editions of the NEC.

Continuous Code Updates & Practical Effects

Key Challenges of the Industry

The NEC undergoes a formal revision process every three years to reflect emerging technology, safety research, and industry best practices. These updates have real-world impacts, such as:

New safety requirements for emerging equipment

Updated installation and conductor sizing rules

Expanded requirements for arc-fault and ground-fault protection

Additions related to modern technologies (EV charging, data cabling paths, etc.)

Even when local jurisdictions adopt NEC editions on delayed timelines, professionals must understand both the latest and locally enforced versions — especially for continuing education, certification prep, and compliance training.

We keep your training content aligned with the most current NEC edition, while providing historical context and comparison when necessary.

Ongoing Education & NEC Knowledge Base

Understanding the NEC goes beyond static lessons. Our content strategy includes:

Code-change highlight blogs — summaries and practical implications of new editions

Interpretation scenarios for tricky articles

Best practice guides for electrical safety and compliance

Insight pieces on how code changes affect installations and maintenance

This positions your program as a source of ongoing code knowledge, increasing learner engagement and long-term relevance.
