WebA CMR rating means the cable can be used in the risers of commercial buildings because they limit the spread of flames better than cables in the CL/CM family. They can be installed anywhere except plenums. CL2R and CL3R are the riser versions of CL2 and CL3, meant to carry higher voltages. CMP: The “P” obviously stands for plenum, so this ... Web19 oct. 2008 · Section 110.14 (C) (1) (a) requires that conductor terminations, as well as conductors, be rated for the operating temperature of the circuit. For example, the load on an 8 AWG THHN, 90°C copper wire is limited to 40 amperes where connected to a disconnect switch with terminals rated at 60°C. This same 8 AWG THHN, 90°C wire is …
