Are underground cables used in cable trays
Some cables trays can be used underground with tray cable rated for direct burial. Wire mesh cable trays are similar to perforated cable trays but they are made of a wire mesh, so they offer a higher degree of ventilation, though they offer slightly less protection, than perforated trays. They offer superior moisture and heat dissipation properties at the expense of protection. A cable pathway or raceway is a protective channel or enclosure made of materials like metal or plastic, used to manage and safeguard electrical cables and wires. Cable trays are above-ground systems that support and organize cables. The biggest difference is how they're installed—trays are exposed. To that end this Bulletin is intended to discuss the types of cables most frequently used in cable trays and the wiring methods permitted in cable trays under the National Electric Code (NEC) NFPA 70.
