Simply, no. There are special tests performed to determine if a cable is made from low smoke producing, slow burning insulating materials. The UL Standard is UL 910. The type of Listed (not Recognized Component) cables that are appropriate for use in plenums have the cable designation followed by a "P" suffix. For example, Type CM becomes Type CMP, Type CL2 becomes CL2P, etc.
BTW, a cable that has a VW-1 rating is typically Recognized Component Appliance Wiring Material (AWM), and may or may not be suitable for wiring external to equipment. It is also worth noting that there are many cables that are both Recognized AWM for certain applications and are Listed for others (including general wiring applications [TH, TEW, etc.] and as machine tool wire [MTW], among others). If your using AWM, double check to be certain that the cable is suitable for external use. A 30 mil PVC jacket is a good starting point. Check with the vendor and UL to see if the cable you're using is appropriate. Putting cable into any environmental air space can bring on many additional restrictions. Please refer to US NEC (NFPA70), Article 300-22 for additional details. For installations in nonUS locations, check the local installation electrical codes for applicable requirements. Peter L. Tarver Northern Telecom [email protected] ------------------------------ Hello everyone, We are using a cable with one of our product which is UL approved and passes UL VW-1 vertical flame test for rated temp. of 80C and rated voltage of 30V. Jacket material is PVC. We are wondering if a customer wants to route this cable through an air plenum of a building, is above approval sufficient? or there are some other OSHA standard which we need to meet? Any suggestions or comments is appreciated. [email protected]
