CSA C22.2/NEMA VE1
Metal Cable Tray Systems, a joint standard published for the United States by NEMA, and published for Canada by CSA, is one of the key cable tray standards in our market. The most recent version of this standard (2002) includes many changes that affect Wire Mesh Cable Tray.
The standard "provides technical requirements concerning the construction, testing, and performance" of cable tray. Test requirements given by the standard are Electrical Continuity Testing and Load Testing; requirements for marking cable trays are also given.
Compliance to this standard is not regulated by NEMA or any other organization in the United States in the manner that National Electrical Code (NEC) compliance is regulated; this standard is a "recommendation" or "suggestion" for cable trays. Cable tray manufacturers may have their products tested by an independent laboratory for compliance to this standard, as Cablofil has done. In Canada, however, this standard is regulated, and compliance is mandatory just as NEC compliance is required in the U.S.
Cablofil hired UL (Underwriters Laboratories) to 3rd party witness testing of our products for compliance with CSA C22.2/NEMA VE1. UL's test witnessing group is separate from the CSA (Canadian Standards Association). Cablofil's CSA Certificate of Compliance is the result of this testing.
