Distance between cable tray span hangers or supports
Support spacing for cable trays must align with the manufacturer's instructions, as outlined in NEC 392. Generally, standard trays require supports every 6 to 10 feet, while heavy-duty, long-span trays can handle distances of up to 20 feet between supports. The spacing between trays, whether horizontal or vertical, depends on various factors like cable type, environment, and tray material. Cable trays are used for supporting. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. Extra-long spans are also used to help reduce the required number of expensive outdoor supports. In long and extra-long span installations, the placement of splice plate locations become much more.
