oskin Posted January 4, 2006 Report Share Posted January 4, 2006 I am hoping someone will be able to give me the specific derating factor for the current carrying capacity of conductors enclosed in air. I also need the source of the info ie ref to a standard.I have looked at a number of cable handbooks and standards and codes and have found heaps on enclosed conductors in thermal insulation and overall derating factors but have not been able to pin down this specific factor. eg of application: internal cabling run in wiring duct of a metalic switchboard.I need this to extrapolate data from manufacturers handbook.i hope someone can help me out.Oskin Link to comment Share on other sites More sharing options...
