  • National Standards for Cable Tray Production

    National Standards for Cable Tray Production

    The most important standards include cable tray standards set forth by NEMA (VE 1 and FG 1), UL 870 for product safety certification, and ISO 9001 for quality management systems. This standard specifies the requirements for nonmetallic cable trays and associated fittings designed for use in accordance with the rules of the Canadian Electrical Code (CEC) Part 1, and the National Electrical Code® (NEC). The flexibility and scalability of cable trays make them an ideal choice for environments where cable density and organization can. Cable tray quality standards have developed into full-fledged systems to ensure these essential components perform to demanding performance requirements. In fact, modern cable tray manufacturing standards cover everything from raw materials to end product testing, the foundation of reliable. The official guidelines that provide information about how strong a cable tray should be are the NEMA standards. Consider NEMA as a kind of rating system that ensures that a tray will not be bent or broken in case of full of heavy power cables.
