An owner has requested CMP-50 plenum communication cable. As far as I can tell, CMP-50 was a listing that was proposed to be added to the National Electric Code but was rejected for the 2002 code, therefore is it not a cable that should be used if it is not an acceptable listing in...
An industry-led task group developed the desired characteristics of a calibration cable to assist in the verification of the NFPA 262/UL910 plenum cable fire test method and instrumentation. A review of existing materials against the requirements yielded several candidates that were manufactured into ...
