NEC Quiz: Article 250, Part Sixteen Answers

Back to Quiz

  1. It's about equipment bonding and bonding conductors (not equipment grounding and grounding conductors as stated). By bonding equipment, you remove differences in potential. We do this with the Equipment Grounding Conductor (EGC), which isn't necessarily a hunk of wire.
     

  2. See the definitions of grounding and bonding in Article 100. You do not want to ground load side equipment, as this achieves nothing.
     

  3. [250.116]. Yes, connect those as well. While 250.118 lists specific equipment, nothing says you can't connect all equipment via bonding jumpers.
     

  4. [250.118]. More. In fact, there are 14.
     

  5. [250.119(A)]. 6AWG.

How the NEC is arranged

  1. The first four Chapters of the NEC apply to all installations.
  2. Article 90 precedes Chapter One, and establishes the authority of the NEC.
  3. Article 80 follows the body of the NEC; it exists as Annex H. It provides the requirements for administration.
  4. Chapters 5, 6, and 7 are the "special" chapters, covering special: occupancies, equipment, and conditions (in that order).
  5. Chapter 8 provides the requirements for communications systems.
  6. Chapter 9 provides tables.
  7. The appendices provide mostly reference information.
  8. Appendix D contains examples that every NEC user should study.
