What is the minimum distance recommended between communications wires and lighting conductors?

The recommended minimum distance of 6 feet between communications wires and lighting conductors is based on safety and interference considerations. This distance helps to minimize the risk of electromagnetic interference that can negatively impact the performance of low voltage communication systems. It also ensures that there is adequate physical separation to prevent potential electrical hazards, such as induction or accidental contact, between the differing electrical systems.

When low voltage communication systems run in proximity to high voltage lighting conductors, there exists a potential for induced voltage from the higher voltage lines to affect the integrity of the data signals in the communication wires. By adhering to the 6-foot separation guideline, contractors help ensure that communications equipment functions reliably and safely, while also protecting both the communication and lighting systems from possible damage.
