Maximum length of cable tray support
The maximum length for cable trays can vary based on installation requirements and standards. Generally, the maximum distance between tray supports is defined by the load capacity, which can be up to 150 meters in specific installations . Additionally, the National Electrical Manufacturers Association (NEMA) provides guidelines for support spans based on load capacity, but specific maximum lengths may vary . Always refer to local codes and standards for precise requirements.
