For horizontal cable tray runs, the support span (distance between side supports) is generally 1.5 to 3 meters. This range ensures structural stability, prevents sagging, and allows for easy maintenance access . For long-span or heavy-duty trays, supports may be spaced up to 6 meters (approximately 20 feet) if the tray is designed to handle the load . At corners, bends, or T-junctions, supports should be installed on each side symmetrically to maintain stability . For vertical or angled tray runs, supports should be fixed to the building structure at intervals preferably less than 2 meters to prevent the tray from bending or cables from being stressed .
In practice, the typical distance between a cable tray and its side support is 1.5–3 meters, with adjustments made for tray type, load, and installation orientation. Always verify spacing against manufacturer specifications and NEC guidelines to ensure safety, structural integrity, and ease of maintenance .
