Materials: Choose the tray material - aluminum, steel, or FRP - based on environmental conditions and load requirements. Proper installation minimizes risks like overheating, fire, and mechanical failure while ensuring compliance with NEC standards. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. Cable Tray Types and When to Use Each 2. 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 similar or. When constructing a custom cable assembly, manufacturers often add filler material to separate different sections and/or to fill in the gaps between the conductors, or wires. Fillers serve multiple functions within a cable from providing added protection against the elements to lengthening the. Ladder trays are typically fabricated from steel (galvanized or stainless) or aluminum, with rung spacing of 6, 9, 12, or 18 inches depending on the load requirements and cable type supported. Standard rung widths range from 6 to 36 inches, with load depths from 3 to 6 inches.
