This self-paced online course covers the general requirements in Article 110 of the National Electrical Code. Article 110 is one of the broadest articles in the NEC, covering general specifications that will apply in addition to the more specific requirements found in later articles.

Upon completion you should be able to:

• Explain what is included in the NEC's general requirements.
• Identify the use of listed equipment.
• Explain how interrupting ratings and short-circuit current ratings address fault current.
• Explain the concept of "mechanical execution of work".
• Identify the importance of field equipment markings, including:
  • Explaining the requirements for indoor and outdoor enclosures.
  • Identify requirements for spaces for energized and non-energized equipment.

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.

Course Summary

• General requirements of the National Electrical Code (NEC) are included in Article 110, which covers approval, installation and use, access and required space for equipment.
• All equipment installed under the NEC must be approved by the authority having jurisdiction (AHJ). Typically, the AHJ will prefer that listed equipment be used when possible, because listing means the equipment has been evaluated by an independent agency.
• The NEC addresses the need to interrupt unintended fault current by providing interrupting ratings and short-circuit current ratings for equipment.
  
• The NEC also addresses safety through the general requirement that installations must be made in a "neat and workmanlike manner," as well as by specific mandates, like requiring unused openings to be closed up and requiring equipment to be protected from damage from paint or other construction activities.
• Equipment must be marked to avoid various hazards, including warnings of flash hazard, marking of available fault current, identification of disconnecting means and accurate labeling of switchboards and panelboards.
• NEC requirements also cover indoor and outdoor equipment enclosures and space requirements for the areas in which equipment is housed.
