This self-paced online course explains requirements in NEC Chapter 6 for equipment that requires special considerations. Chapter 6 covers a variety of equipment types, only some of which will be discussed in any detail in this module.
Upon completion you should be able to:
- Identify the scope, key terms and major provisions of select articles in Chapter 6, including:
- Article 600: Electric Signs and Outline Lighting
- Article 625: Electric Vehicle Charging System
- Article 626: Electrified Truck Parking Spaces
- Article 630: Electric Welders
- Article 645: Information Technology Equipment
- Article 680: Swimming Pools, Fountains, and Similar Installations
- Article 695: Fire Pumps
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- Chapter 6 covers a variety of equipment types, only some of which will be discussed in this module.
- Article 600 covers "the installation of conductors, equipment, and field wiring for electrical signs and outline lighting, regardless of voltage." Signs must be listed. Commercial buildings and commercial occupancies with pedestrian access must have an outlet dedicated for sign use.
- Requirements for sign disconnecting means are slightly different than for other types of equipment. Because they may be used in many different locations, portable or mobile signs are required to have factory-installed GFCI protection. Numerous issues regarding neon tubing are addressed in this article.
- Article 625 covers electric vehicle charging systems.
- Article 626 addresses electrified truck parking spaces.
- Requirements for arc welders (Article 630) must take into account noncontinuous duty cycles and inrush current when the welder is started“ which affect conductor ampacity and overcurrent protection â€“ and grounding of the secondary circuit.
- Article 645, which addresses information technology equipment rooms, provides alternative wiring methods and conditions that must be met in order to use those alternative methods.
- Article 680 covers swimming pools, fountains and similar installations. This article addresses shock hazard by providing equipotential bonding and by locating metal equipment and electrical equipment away from pool areas as much as possible.
- Fire pumps (Article 695) are also addressed by NFPA 20 and NEC Article 430. Fire pumps require extremely reliable power sources, so this article addresses power continuity, wiring and voltage drop.
