NEMA releases cable tray guidelines

By Plant Engineering Staff December 5, 2006

Information on maintenance and system modification of cable tray systems can be found in the recently-published third edition of “VE 2-2006, Cable Tray Installation Guidelines” from NEMA. This practical guide for proper cable tray system installation also addresses shipping, handling and storing of cable trays.

Cable tray system design must comply with “NEC Article 392,” “NEMA VE 1” and “NEMA FG 1,” and follow safe work practices as described in “NFPA 70E.” The guidelines in this publication are useful to engineers, contractors and maintenance personnel.

“NEMA VE 2-2006” has been revised to reference the 2005 version of the NEC, and provides clarification for grounding and bonding cable trays, as well as recent cable tray product developments.

“VE 2-2006” may be downloaded free, or a hardcopy purchased for $69.00 by visiting NEMA’s website at or by contacting IHS at (800) 854-7179 (within the U.S.), (303) 397-7956 (international), (303) 397-2740 (fax).
