The NEC article 100 and 250-70 defines bonding as: The grounding mechanism must provide a reliable means to safely conduct the voltages imposed by lightning, line surges, or unintentional contact with high voltage lines or equipment to ground. “A conducting connection, whether intentional or unintentional, between electrical circuits or equipment and the earth, or some conducting body that serves in place of the earth".”Įlectrical systems and communication cabling systems that are required to be grounded must be connected to the earth. This means designing a complete grounding and bonding system that goes beyond the basic "green-wire" methodology. The sensitivity of the electronic equipment requires that the telecommunications cabling and power be effectively equalized to prevent loops or transients that can damage the equipment. ![]() However, simply grounding to structural steel isn’t enough when tackling telecommunications systems. ![]() Although similar grounding principles apply, understanding the telecommunications terminology and special considerations has been a challenge.Īs with traditional electrical grounding, telecommunications networks and equipment should be grounded to the electrical service. With the increasing demand for computer network installations, telecommunications grounding and bonding has become a growing opportunity for electrical contractors. Why Do We Need Grounding and Bonding for Telecommunication Systems? ![]()
