Are cable tray supports considered pipe supports
Cable trays are a support system for electrical cables, power, signal, and communication and optical fiber cables. According to DIN EN 61537, a cable support system is used to support and house cables. The. Do we only need to indicate that the cable tray is designed as a support in the drawings, or should there be physical signage upon installation as well? As far as cable tray loads go, I do not yet have all my cables designed (still lacking load information), but will calculate all the cable weights. Answer: No. NEC section 300-8 does not permit any tube, pipe, or equal for water, air gas, drainage, steam, or any service other than electrical in raceways or cable trays containing. While focused attention is paid to large primary structures like pipe racks and foundations, secondary supports-including cable tray brackets-quietly carry their share of the load but rarely receive proportional engineering attention. For proper installation, design, and maintenance, adherence to international standards is essential. One of the most recognized frameworks globally is the IEC standard for.
