Horizontal cable tray distance

Home / Horizontal cable tray distance

Horizontal Runs: Cables should be secured at their start, end, and turns, and every 3 to 5 meters along straight horizontal sections. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. This spacing is crucial for adequate maintenance access, ease of inspection, and ensuring proper airflow for effective heat dissipation. Cable ladder systems and cable tray systems shall be manufactured in accordance with BS EN 61537, channel support.
