  • 2020 National Electrical Code® Style Manual
    2020 NATIONAL ELECTRICAL CODE® STYLE MANUAL 1 FOREWORD August 2020 The National Electrical Code® is used nationally and internationally as the basis for safeguarding persons, buildings, and their contents from hazards arising from the use of electricity. It is vitally important that the text be as explicit as possible, and that maximum consistency be achieved in the language used in the text. The Code contains those provisions considered necessary for safety and thus is widely used as a basis for legal enforcement in the installation of electrical conductors and equipment in buildings and certain other premises (as detailed in the Code itself); this places a major responsibility on those involved in the preparation of document text to use forms of expression that promote uniform interpretation. The National Electrical Code Correlating Committee has recognized these responsibilities and has issued this manual. Preparation and Date of Adoption. This manual was originally prepared by the Editorial Task Group of the National Electrical Code Committee and adopted by the National Electrical Code Correlating Committee on May 13, 1969. It was amended September 22, 1975, October 11, 1984, October 12, 1989, and May 9, 1994. In January 1999, the Correlating Committee Task Group on the Usability of the NEC rewrote the manual. It was adopted by the National Electrical Code Correlating Committee on March 19, 1999 and by the Standards Council on April 15, 1999. It was amended March 1, 2001, January 15, 2003, and August 9, 2011, August 2015, and December 2020. 2 TABLE OF CONTENTS Foreword ........................................................................................................ 2 Chapter 1 General 4 1.1 Purpose ............................................................................................

  • 90 INTRODUCTION to the National Electrical Code
    ARTICLE INTRODUCTION TO THE 90 NATIONAL ELECTRICAL CODE Introduction to Article 90—Introduction to the National Electrical Code Many NEC violations and misunderstandings wouldn’t occur if people doing the work simply understood Article 90. For exam- ple, many people see Code requirements as performance standards. In fact, the NEC requirements are bare minimums for safety. This is exactly the stance electrical inspectors, insurance companies, and courts take when making a decision regard- ing electrical design or installation. Article 90 opens by saying the NEC isn’t intended as a design specification or instruction manual. The National Electrical Code has one purpose only, and that’s the “practical safeguarding of persons and property from hazards arising from the use of electricity.” The necessity of carefully studying the NEC rules can’t be overemphasized, and the role of textbooks such as this one is to help in that undertaking. Understanding where to find the rules in theCode that apply to the installation is invaluable. Rules in several different articles often apply to even a simple installation. Article 90 then describes the scope and arrangement of the NEC. The balance of this article provides the reader with informa- tion essential to understanding the Code rules. Typically, electrical work requires you to understand the first four chapters of theNEC which apply generally, plus have a working knowledge of the Chapter 9 tables. That understanding begins with Article 90. Chapters 5, 6, and 7 make up a large portion of the Code, but they apply to special occupancies, special equipment, or other special conditions.

  • Conductor Sizing and the National Electrical Code
    Conductor Sizing and the National Electrical Code The National Electrical Code requirements for conductor sizing and overcurrent protection have always been confusing and complex. Factors that must be consider include: 1. Continuous loads 2. Terminal temperature ratings 3. Conductor insulation 4. Conductor ampacity 5. Special application 6. System voltage NEC Section 240-3 requires the branch circuit, feeder, and service conductors to be protected against overcurrent in accordance with their ampacities as specified in Table 310-16. However, Section 240-3 contains twelve rules that modify the general requirement and permit the conductors not to be protected in accordance with their ampacities, they include: 1. Power Loss Hazard 2. Devices Rated 800 Amperes or Less 3. Tap Conductors 4. Motor-Operated Appliance Circuit Conductors 5. Motor and Motor-Control Circuit Conductors 6. Phase Converter Supply Conductors 7. Air-Conditioning and Refrigeration Equipment Circuit Conductors 8. Transformer Secondary Conductors 9. Capacitor Circuit Conductors 10. Electric Welder Circuit Conductors 11. Remote-Control, Signaling, and Power-Limited Circuit Conductors 12. Fire Alarm System Circuit Conductors With so many different Code rules that modify the general requirements, it does become overwhelming to a circuits conductor and overcurrent protection device. However the following steps and examples should help you understand the basic rules of conductor sizing and protection. Step 1 - Size the overcurrent protection device in accordance with Sections 210-20(a), 215-3, and 384-16(d). These three NEC rules required the overcurrent protection device (breaker or fuse) be sized no less than 100% of the noncontinuous load, plus 125% of the continuous load.

  • Arc Fault Circuit Interrupter Explained
    What is an Arc Fault Circuit Interrupter? Courtesy of Wikipedia, the free encyclopedia An Arc Fault Circuit Interrupter (AFCI ) is a circuit breaker designed to prevent fires by detecting a non-working (i.e., non-intended/non-useful) electrical arc and disconnect power before the arc starts a fire. An AFCI should, but does not always, distinguish between a working arc that may occur in the brushes of a vacuum cleaner, light switch, or other household devices and a non-working arc that can occur, for instance, in a lamp cord that has a broken conductor in the cord from overuse. Arc faults in a home are one of the leading causes for household fires.[1] AFCI’s resemble a GFCI/RCD (Ground- Fault Circuit Interrupt/Residual-Current Device) in that they both have a test button, although it is important to distinguish between the two. GFCIs are designed to protect against electrical shock, while AFCIs are primarily designed to protect against arcing and/or fire. Electrical Code Requirements Starting with the 1999 version of the National Electrical Code (NEC, also called NFPA 70) in the United States and the 2002 version of the Canadian Electrical Code in Canada (CSA Standard C22.1), the national codes require AFCIs in all circuits that feed receptacles in bedrooms of dwelling units. This requirement is typically accomplished by using a kind of circuit-breaker (defined by UL 1699) in the breaker panel that provides combined arc-fault and over current protection. Not all U.S.A. jurisdictions have adopted the AFCI requirements of the NEC as written.
