Introduction to Cable Tray Technology

Quick answers: A cable tray is an open, rigid support system used to route and organise electrical cables in buildings and industrial facilities — replacing conduit in most large-scale installations. The three main types are ladder tray, perforated (solid-bottom) tray, and wire. As with anything electrical, the National Electrical Code (NEC) has rules tied to its use. 2 defines a cable tray system as “a unit or assembly of units or sections with associated fittings forming a rigid structural system used to securely fasten or support cables and raceways. The Cable Tray ng standards, performance standards, test standards and application in this document have been tested extens ompetent professional en completely installed, without damage either to conductors or.
