October 8, 2009—

The National Electrical Manufacturers Association (NEMA) has published VE 1-2009 Metal Cable Tray Systems. The standard is also published by the Canadian Standards Association as CSA C22.2 No. 126.1-09.

NEMA VE 1-2009/CSA C22.2 No. 126.1-09 is the third edition of the specification for metal cable tray systems for use in North America. It provides technical requirements concerning the construction, testing, and performance of metal cable tray systems. It supersedes the second edition, published in 2002.

Revisions include changes to the fill depth section and requirements for load testing for wire mesh. The load class designation table was also split into separate tables for the United States and Canada.

"VE 1/CSA 22.2 No. 126.1 is a helpful resource to a variety of audiences, including personnel at warehouses, data centers, paper mills, oil refineries and manufacturing plants," said Bob Slaga, chair of the Cable Tray Technical Committee and member of the Cable Tray Section. "Through this revision, NEMA's Cable Tray Section hopes to continue to promote safety of persons and property by the proper selection and use of metal cable tray systems."
