In the of buildings, a cable tray system is used to support insulated used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or systems, and are commonly used for cable management in commercial and industrial construction. They are especially useful in situations where changes to a wiring system are anticipated,.
Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough. A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray throug.
Proper planning for installing cable tray includes calculations based on loading, support systems, cable/wire fill and spacing, conductor types, securing of the cables and wire, and proper grounding and bonding are all important aspects of cable tray installation. All metallic cable trays shall be grounded as required in Article 250. An EGC conductor in or on the cable tray. This guide covers the critical steps, from selecting the right electrical cable tray and performing accurate cable fill. NEMA VE2 addresses cable tray installation and provides information on maintenance and system modification. NEMA VE2 was developed by the NEMA Cable Tray Section, of which MP Husky is a charter member. This provides a safe path for any stray electrical currents to flow safely into the earth, avoiding damage to your equipment and reducing the risk of electric shocks. There are three wiring. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
