Only the most relevant proposals that align with safety and compliance standards progress through the process.
Panels Composed for Code Creation
Multiple groups composed of professionals, such as electricians, inspectors, and researchers, scrutinize these proposals. There are 18 panels, each responsible for specific parts of the code, which assess the practical applicability and significance of the proposals. This collective expertise ensures that the proposed alterations benefit the entire electrical industry.
Developing Drafts and Public Comments
The reviewed proposals are compiled into a preliminary draft. This draft is subsequently made accessible for public review and input. During this phase, approximately 700 changes were shortlisted for a second draft, allowing stakeholders to express their opinions and concerns.
Formalizing Amendments
Upon incorporating feedback and undergoing review by the correlating committee, the finalized changes are adopted into the code. Most revisions were approved, some with additional modifications, paving the way for the integration of contemporary practices in the standards. The adoption ensures that the code remains a foundational document for electrical compliance and safety.
Key Focus of the Course
This course is a comprehensive exploration of approximately 50 code changes that have significant implications for power-limited technicians. About half of these changes address general topics such as definitions and wiring methods. The remainder involves codes that directly apply to power-limited technicians, covering entire articles rather than just selected segments.
To deliver the content effectively, each change is presented with a clear illustration, followed by a headline indicating the nature of the modification, whether it's a new section, revision, or alteration in the code language. A brief description outlines what's been changed, and the 2020 version of the NEC is provided with marked deletions from the 2017 NEC. New language added to the code is highlighted with a cut-and-paste overlay for clarity.
You'll also engage with questions throughout the course to verify participation and support learning. It's recommended to have a copy of the 2020 NEC nearby for reference during the course, which can assist in answering questions or supplementing information. If questions or concerns arise, you're encouraged to leave comments or questions in the suggestion box for further clarification.
Display of Information
Organization of Code Adjustments
The National Electrical Code (NEC) divides its extensive guidelines into various levels to enhance clarity. It starts with chapters, each addressing a broad theme, such as wiring or installations. These chapters contain articles that further elaborate on the subject. Each article is subdivided into parts focused on specific elements within the broader category. Sections within these parts delve into key topics, which may be standalone paragraphs or more detailed subdivisions. Lists include conditions that either all need to be met or that are optional. Exceptions and informational notes provide additional guidance and context.
Comprehensive Examination
In this section, you'll gain an extensive understanding of code alterations. Each change is presented with a snapshot illustrating the modification and a thorough exploration of its implications in your work environments. The course offers context by comparing the past and present code formulations. You'll notice changes with previous terms struck through and new additions highlighted for clarity. Linking the reasons for these updates will deepen your grasp of their significance and practical application.
Overview and Details
For a detailed view, each change is prefaced with an introduction and illustrated description. A headline categorizes the type of modification, whether it's a new section, a revised text, or a comprehensive overhaul. The text itself includes both, showing what's removed and highlighting what's added. Detailed overlays of the new language then provide a clearer understanding of the fresh requirements. This structured approach ensures you're well-equipped with pertinent information using the 2020 NEC standards.

NEC Organization and Terms
Chapters and Themes
In the NEC, the codes are first divided into chapters. Each chapter focuses on a broad subject, covering a wide range of aspects related to that subject, ensuring comprehensive coverage.
Articles and Elements
Within each chapter, you'll find articles. These articles serve as the broad elements within the larger theme covered by the chapter, breaking down the subject matter into more focused segments.
Segments and Regulations
Some articles are further divided into segments. These segments contain regulations that typically only apply within a specific context. Always pay close attention to which segment is relevant to your work.
Sections and Subdivisions
Sections address significant topics. They may appear as a single paragraph or be divided into smaller parts, known as subdivisions. These subdivisions include the section number followed by additional identifiers.
Lists and Criteria
Within sections, lists are used to denote criteria that must be met. Lists may require either full compliance with all items or allow for individual items to fulfill requirements, depending on the situation.
Special Conditions and Use-Cases
There might be specific conditions—exceptions—that remove the need to follow certain section items. These exceptions typically occur when set conditions are satisfied and are often italicized for emphasis.
Advisory Notes and Recommended Procedures
Sections can include advisory notes that guide compliance with recommended procedures. These notes are not mandatory, but they provide useful pointers toward best practices.
Code Implementation Charts
Sometimes, sections will reference charts that provide practical details on how a particular code should be implemented. These charts offer clarity and direction without the need to repeat text throughout the document.
Overview of 2020 Code Updates
The 2020 NEC has undergone significant updates in various areas. These changes are a result of over 3,500 public proposals with about 1,400 suggested revisions. In general, the revisions reflect advances in technology and concerns regarding safety and craftsmanship. Here, 18 code-making panels comprised of industry professionals—electricians, inspectors, manufacturers, and researchers—played a crucial role in evaluating each proposal.
The code revision process involved multiple stages. Initially, proposals were compiled into a first draft, which was then made publicly available for feedback. A detailed assessment followed, leading to approximately 700 amendments reaching the second draft, most of which were formally accepted after further review.
