Description of National Electrical Code 2020 Pdf

There are several new articles in NEC 2020. Article 242 is one of four for surge protection.

Surge protection, devices, and arresters are covered in Article 242 Overvoltage Protection, which incorporates Articles 280 and 285.

Industrial and hazardous environment 600V Type P cables are covered by Article 337 Type P Cable.

On medium voltage conductors and cables, article 311 MV Conductors and Cables elaborates on the now-deleted article 328.

Article 800 General Requirements for Communications Systems consolidates the existing content of 2017 NEC chapter 8 into one article and addresses requirements for communication circuits, such as television and radio distribution antennae and network-powered broadband systems. –

Features of National Electrical Code 2020 Pdf

  • As a result of the Code not being covered by federal law, multiple versions of the NEC are enforced across the United States. A “uniform code” is instead a collection of recommendations that any state can accept and use as they see fit. Each state or local jurisdiction has the ability to regulate the application of the NEC. States may choose to change the Code or otherwise alter it before adopting it. A state’s efforts to standardise the enforcement of safe electrical practises are frequently built on the NEC.
  • Since different states may impose different editions of the NEC, having a copy of the NEC guidebook handy may be useful. The NFPA maintains a map showing which states have adopted the most recent edition of the NEC. In spite of the fact that over 30 states have accepted the most recent 2017 version, there is one state that still uses the 2011 edition, and three others that still use the 2008 edition.
  • It’s a mystery why each state doesn’t simply adopt the most recent Code. It’s a difficult question to answer. The opinion on how tightly electrical safety requirements should be implemented might differ, just like many other regulations that are left to state governments, such as speed limit and traffic legislation. Even though the National Electrical Code requirements may only be updated once every five to ten years, this means that more than one edition will be issued throughout this time period. States are also under pressure from local businesses and building owners when it comes to enforcing regulations and policies.
