Article 840 of the National Electrical Code (NEC) 2023 edition covers requirements for the installation and use of premises-powered broadband communications systems. This article sets out guidelines for the installation of broadband communications systems in various environments, as well as specific requirements for the type of system that can be used for premises-powered broadband communications.
NEC 2023 is the latest edition of the National Electrical Code, which is developed and published by the National Fire Protection Association (NFPA). The NEC is a widely used set of standards that is adopted by many jurisdictions in the United States and other countries as the basis for their electrical safety regulations.
Premises-powered broadband communications systems are a type of system that provides high-speed internet, television, and other communication services to residential and commercial buildings. These systems are becoming increasingly popular as more people rely on high-speed internet for work, entertainment, and communication.
The first section of Article 840 covers general requirements for premises-powered broadband communications systems. This section sets out guidelines for the maximum power output of the system, as well as requirements for the minimum separation between the system and other electrical equipment. The section also includes requirements for the type of grounding that must be provided for premises-powered broadband communications systems.
The next section of Article 840 covers requirements for the installation of premises-powered broadband communications systems in different environments. This section sets out specific requirements for the installation of these systems in residential and commercial buildings, as well as requirements for the installation of these systems in outdoor environments. The section also includes requirements for the type of conduit or raceway that must be used to protect the system.
The following section covers requirements for the use of premises-powered broadband communications systems. This section sets out specific requirements for the type of equipment that can be connected to the system, as well as requirements for the maximum number of connections that can be made to the system. The section also includes requirements for the type of cabling that must be used to connect equipment to the system.
The final section of Article 840 covers specific types of premises-powered broadband communications systems, such as powerline carrier (PLC) systems and coaxial cable systems. These types of systems have unique installation requirements that must be followed to ensure their safe use. For example, PLC systems must be installed in a way that minimizes the risk of interference with other electrical equipment, while coaxial cable systems must be grounded in a specific way to ensure that the system is safe.
One of the key goals of Article 840 is to ensure that premises-powered broadband communications systems are installed and used in a way that minimizes the risk of fire or other hazards. To achieve this goal, the article sets out requirements for the maximum power output of the system, as well as guidelines for the minimum separation between the system and other electrical equipment. The article also sets out specific requirements for the type of grounding that must be provided for premises-powered broadband communications systems.
Another key goal of Article 840 is to ensure that premises-powered broadband communications systems are protected from physical damage and environmental hazards. This is particularly important in environments where the system may be exposed to moisture, corrosive chemicals, or other hazards. The article sets out specific requirements for the type of conduit or raceway that must be used to protect the system, as well as requirements for the type of cabling that must be used to connect equipment to the system.
The requirements for the installation and use of premises-powered broadband communications systems are also important, as these installations may involve more complex installation procedures than other types of electrical installations. For example, the installation of premises-powered broadband communications systems may require special equipment and expertise to ensure that the installation is done correctly.
The final section of Article 840 covers specific types of premises-powered broadband communications systems, such as powerline carrier (PLC) systems and coaxial cable systems. These types of systems have unique installation requirements that must be followed to ensure their safe use. For example, PLC systems must be installed in a way that minimizes the risk of interference with other electrical equipment, while coaxial cable systems must be grounded in a specific way to ensure that the system is safe.
It’s important to note that Article 840 is just one part of the NEC, and there are many other articles that cover different aspects of electrical safety. However, Article 840 is an important part of the NEC as it provides specific guidelines for the installation and use of premises-powered broadband communications systems.
In conclusion, Article 840 of NEC 2023 covers requirements for the installation and use of premises-powered broadband communications systems. The article sets out guidelines for the installation of broadband communications systems in various environments, as well as specific requirements for the type of system that can be used for premises-powered broadband communications. The goal of Article 840 is to ensure that premises-powered broadband communications systems are installed and used in a way that minimizes the risk of fire or other hazards, and that they are protected from physical damage and environmental hazards. Following the guidelines set out in Article 840 can help ensure that electrical installations are safe and reliable.
