OVERVIEW

Grounding and bonding systems are very important for telecommunications systems. These systems guarantee that telecommunications systems run as designed without errors associated with improper grounding of equipment. Studies indicate that 90 percent of all on-site problems are due to nonexistent or improper grounding and bonding practices.

Telecommunications grounding and bonding is additional grounding and bonding installed specifically for telecommunications. This is not a replacement for grounding and bonding specified by the NEC but typically is additional to address telecommunications system performance. This chapter will describe grounding and bonding systems required by communication cabling systems.

NATIONAL ELECTRICAL CODE

The National Electrical Code (NEC) is published by the National Fire Protection Association. The NEC is a code document that defines the requirements for installation of electrical conductors and electrical equipment within public and private buildings. The purpose of the NEC is practical safeguarding and protection for both individuals and property from hazards from the use of and exposure to electricity.

The NEC was originally developed as a unified effort by insurance, electrical, and architectural companies. Each type of company has a common interest in promoting electrical safety in commercial and residential buildings. Today this document serves as the basis for most electrical and communication cabling related codes that must be followed during a cable installation.

The NEC is a comprehensive set of codes related to both electrical and communication cabling. Communication cabling is covered in Chapter 8 of the NEC and is titled "Communications Systems." Article 800 covers the installation of...
