Which type of cable tray should be used for inbound cable management
For a few types of installations, the National Electrical Code (NEC) specifies the cable tray type to be used: Single conductor cables and Type MV cables must be installed in ladder or ventilated trough cable trays. Cable tray systems are structural components used to support insulated conductors and control, instrumentation, and communication cables. They are typically installed overhead, along walls, or under raised floors in electrical rooms, industrial plants, process areas, and commercial buildings. Rather than enclosing cables inside conduit, cable trays provide an open, ventilated support system that allows: Because of this flexibility, cable trays are commonly used in. What type of cable tray should be used for the main runs of a cable tray wiring system? The cable tray types to choose from are ladder, ventilated trough, or solid bottom.
