The 2014 NEC provides an accurate, reliable, and authoritative account of the hundreds of significant revisions in the 2014 Code.
This course provides coverage of significant changes in the 2014 National Electrical Code®. With every new edition of the NEC, some of the changes
include new requirements to sections, while some of the changes include entirely new articles. Some changes are revisions to existing requirements
while others are deletions to some existing requirements.
Chapter 7, which covers special conditions, is the third of the NEC chapters that deal with special topics. As we have seen, Chapters 5 and 6 cover special occupancies and special equipment respectively.
Special Condition is a situation that doesn’t fall under the category of Special Occupancies or Special Equipment, but creates a need for additional
measures consistent with other NEC Chapters whose aim is to ensure the safeguarding of people and property.
Chapter 8 of the NEC covers the wiring requirements for communications systems such as telephones, radio and TV antennas, satellite dishes, closed-circuit television (CCTV) and cable TV (CATV) systems, as well as network-powered and broadband-powered Communications systems.
Communications systems are not subject to the general requirements contained in Chapters 1 through 4 or the special requirements of Chapters 5 through 7, except where a Chapter 8 rule specifically refers to one of those chapters. Moreover, installations of communications equipment under the exclusive control of communications utilities located outdoors, or in building spaces used exclusively for such installations, are exempt from the NEC ARTICLE 700 Emergency Systems.
By the end of this course, you will be able to:
• Recognize that the NEC contains provisions that are considered necessary for safety; compliance therewith and proper maintenance results in an installation that is essentially free from hazard
• Identify the importance of surge protection for critical safety systems
• Summarize the wording for safety and warning labels applied to distribution equipment
• Describe the installation requirements that are needed for safe installation and operation of fire alarm systems
• Recognize that the NEC contains provisions that are considered necessary for safety. Compliance therewith and proper maintenance results in an installation that is essentially free from hazard
• Identify the requirement for safe installation of grounding for radio and television equipment antenna lead-in surge protectors
• Identify the safe voltage output guidelines for the power source of non-power-limited fire alarm circuits
• Explain the requirements for the safe installment of exposed NPBC cables
