What type of cable is laid along the cable tray
Tray cable is a widely used type of multiconductor or multipair cable approved for installation in cable raceways and cable trays. Many cable tray rated cables include a crush and impact test as part of the listing and are rated as exposure rated (ER). It is the standard wiring method for industrial plants, commercial buildings, and utility installations where cable trays provide accessible. The primary rulebook used in the safe use of cable trays is NEC Article 392. This is a description of how to select, install, and support these metal or plastic frames, on which electrical wires are installed.
