The National Electrical Code Article 318 was written primarily for verifying the cable fill in cable trays but little has been done to convert this information into a design procedure. For the purposes of this guideline, a qualified technician is. , is a welded wire-mesh cable management system made of high-strength steel wire. It is used to manage cables for light B manufactures its cable tray in a range of materials with a variety of finishes.
