That is, cable trays are infrastructure used to support and convey electrical cables - which are not enclosed, in the manner of conduit. By contrast, the NEC defines a conduit as a “raceway that is circular in cross-section, flexible, metallic, and liquid-tight without a. Conduit systems are enclosed pipes that require precise bends, threading, and pulling. Cable trays, on the other hand, create an open, structural pathway. In this guide, we will break down the strengths of both systems. Some tray cable, with XLPE insulation (cross-linked polyethylene), is sunlight resistant and suitable for installation in free air and hazardous locations - although this goes according to a case-by-case basis.
