Answer:
The National Electrical Code (NEC) covers a comprehensive range of subjects related to electrical wiring and installations. Communication circuits are specifically covered under NEC Article 800. This article details the guidelines and requirements for the installation of communication circuits to ensure safety and reliability.

Detailed Explanation:

NEC Article 800 - Communication Circuits:

  1. Scope and General Requirements:

    • Article 800 applies to the installation of communication circuits, which include telephone, telegraph, outside wiring for fire and burglar alarm systems, and other similar central-station signaling systems.

  2. Installation Standards:

    • The standards set forth ensure that communication circuits are installed in a manner that minimizes the risk of electrical hazards.
    • This includes the use of suitable materials and protection against physical damage, proper grounding, and following defined spacing requirements between communication circuits and power conductors.

  3. Wiring Methods:

    • The article details acceptable wiring methods and the types of cables and raceways that can be used for communication circuits.
    • It specifies the conditions under which different types of cabling, such as coaxial and fiber optic cables, can be installed.

  4. Separation from Power Conductors:

    • To prevent potential interference and safety issues, Article 800 includes clear guidelines on the separation between communication circuits and power conductors.
    • There are specific rules for maintaining distances and physical barriers to ensure the circuits do not interfere with each other or pose a hazard.

  5. Grounding and Bonding:

    • Effective grounding and bonding are pivotal to the integrity and safety of communication circuits.
    • The NEC article outlines how communication circuits should be grounded to protect against voltage surges and assures that the grounding methods comply with the comprehensive grounding rules detailed in Chapter 8.

Solution By Steps:

  1. Reference Article 800 in the NEC Code:

    • Check the latest edition of the NEC code book or standard summaries available online or in libraries to confirm the specific requirements listed under Article 800.

  2. Review Installation Guidelines:

    • Ensure that the installation of communication circuits adheres to NEC guidelines to avoid violations or potential hazards.

  3. Ensure Proper Grounding and Separation:

    • Follow the grounding and separation requirements precisely to maintain the safety and integrity of the communication system.

Final Answer:

Communication circuits are covered in NEC Article 800.

This comprehensive article ensures that all installations are safe, reliable, and conform to the established electrical standards.
