Should surge protective devices be installed at entrances of conductive communications systems?

Surge protective devices (SPDs) play a crucial role in safeguarding sensitive electronic equipment from power surges and electromagnetic interference, which can be particularly damaging in conductive communication systems. Installing SPDs at the entrances of these systems is essential as it helps to create a barrier that protects against external voltage spikes that could intrude through communication lines. This protection is vital because communication lines are often vulnerable to transient overvoltages caused by lightning strikes, power surges, or other disturbances in the electrical network.

By always installing SPDs at these entrances, you can significantly reduce the risk of damage to critical infrastructure, ensuring the reliability and longevity of the communication systems. This preventive measure enhances the overall resilience of the system and maintains effective operation in the face of external electrical disturbances. It is a standard best practice across various types of communication systems, not limited to specific ones like CATV or data systems. This broad applicability supports the overarching goal of protecting all types of communication infrastructure from potentially harmful surges.
