Headend & Distribution System Construction
The System Contractor must adhere to both national and local
building codes when constructing a Broadband CATV System.
This includes, but is not limited to the NEC, NFPA Codes and local
building ordinances.
Related National Electrical Code (NEC) Articles
Article 250 - Grounding
is one of the largest, most important,
and least understood articles in the NEC. As specified in Section
90-1(a), safety is the key element and purpose of the NEC. Proper
grounding and bonding is essential for maximum protection of life
and property. If over-current protection is considered the first line of
defense, grounding could be considered the last line of defense.
Article 810 - Radio and Television Equipment
covers radio and
television receiving equipment and amateur radio transmitting and
receiving equipment, but not equipment and antennas used for
coupling carrier current to power line conductors.
Article 820 - Community Antenna Television and Radio
Distribution Systems
covers coaxial cable distribution of radio
frequency signals typically employed in community antenna television
(CATV) systems.
