[pdf] The National Electrical Manufacturers Association (NEMA) Standard VE 1-2002 provides guidance for metal cable trays and associated fittings designed for use in accordance with the rules of the NEC. The fire rating of slot-type fire-resistant Cable Trays is primarily determined by their fire endurance (the time during which the structure and electrical circuit remain intact under standard flame conditions). Route. us-trations without notice. A cable tray may comply with a product standard, an installation code. In addition, this document contains several references to provisions of the National Electric Code (NEC), which is published by the National Fire Protection Association (NFPA). Because of its closed design, this type of tray should e used in applications where there is minimal risk of heat generation and buildup.
