Support Spacing: Remember the NEC requires no more than 4 feet of support spacing. In this blog, we'll focus on support spacing for perforated, ladder and wire mesh cable trays and reference the National Electrical Code (NEC). Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency. A cable support system consists of cable support lengths and system components, such as cable support fittings, support elements, mounting elements and system acces-sories. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned in this technical guide only apply to our own cable management ranges and cannot under any circumstances be transposed to si osure, overheating or.
