This chapter introduces the reader to NEC®, National Electrical Code. The NEC® articles of code are designed to provide a standard for safety that protects against electrical shock and thermal effects, as well as dangerous overcurrents, fault currents, and overvoltage. The methods associated with the application of NEC® articles are illustrated through example problems. The NEC® articles cited are subject to change due to periodic code revisions and were meant to be valid at the time of development of these problems. The chapter presents the exploration of the physical, chemical, and thermal aspects of arc flash phenomena. It aims to enhance technicians’ and engineers’ appreciation of the reasoning behind arc flash hazard analysis requirements and the need for arc flash personal protective equipment. Certifications and certification labels on electrical equipment are intended to provide the end user, installer or integrator a measure of assurance that the labeled equipment is safe when applied or used as prescribed by the manufacturer.
