Once the cable is installed in an open cable tray installation, take care to protect the exposed cables from falling objects or debris that could cause damage to the cable. Non-metallic supports and hardware may require special load bearing considerations because of material composition and application temperature. Consideration should be given to loads associated with future cable additions or any other additional loads applied to the cable tray installation and or the tray support system.
Supports for cable tray installations should provide strength and working load capabilities sufficient to meet the load requirement of the cable tray wiring system. 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. NEMA VE2 was developed by the NEMA Cable Tray Section, of which MP Husky is a charter member. NEMA VE2 addresses cable tray installation and provides information on maintenance and system modification. MP Husky Cable Trays are NEMA VE 2-2013 compliant.
