Residential telephone conductor installations must comply with which article?

The installation of residential telephone conductors falls under Article 800 of the National Electrical Code (NEC). This article specifically addresses the requirements for the installation and maintenance of communications circuits, including telephone systems. Article 800 outlines provisions such as wiring methods, bonding and grounding, and the protection of conductors, ensuring safe and effective installation practices for communications equipment.

Articles 810, 820, and 725 cover other topics. For instance, Article 810 pertains to the installation of radio and television equipment, including antennas, while Article 820 relates to community antenna television (CATV) systems. Article 725 discusses low voltage and signaling circuit installations, which are not specifically aimed at telephone systems. Understanding the distinctions among these articles helps in correctly identifying the standards applicable to specific types of installations, highlighting why Article 800 is the appropriate reference for residential telephone conductor installations.
