Yooper,
I know, but / and thanks for helping drive the discussion toward NEC subtle details...
Apparently, by driving a Class 2 classification (in this example) based on the power limited supply that feeds it and the Class 2 devices interconnected by the wiring... It is still OK to use Class 1 wiring methods, in other words upgrade the wiring which would then allow the combined conductors in the same raceway (at least, so I'm told.)
Correcting my original post - the Modbus and Lon bus orange wiring in the photo example are 24 AWG with 300 volt rated (CM on the jacket) insulation with soldered twist splices covered by wire nuts.
