CABLE TRAY INSTALLATION LOCATIONS
Where not allowed: NEC Article 392 states that cable tray systems shall not be installed in hoist ways or where subject to severe physical damage. Metal cable tray systems may support conductor types allowed in certain areas to include environmental air and classified locations. The restrictions apply to the conductors being installed, not the cable trays. Local codes apply.
Provide access: Cable tray systems are to be installed so that they are accessible. If possible, 300 mm (12 in) minimum should be left above or between installed systems to allow for cable installation and maintenance.
In possible fire areas: Cable tray installations should avoid possible fire areas. Should that not be possible, and if there are critical circuits involved, stainless steel cable tray and fire resistant cables should be considered. Wrapping cable tray in a flame-resistant blanket might create a cable-heating problem without a fire. Installing a physical fire shield beneath a cable tray system may provide only limited improvement and create other issues.
