Dennis: OK, I think you done real good! and below see also the discussion on the question first posted in the link above:




The low voltage thermostat wires are not permitted to be run in the same cable or conduit because they do not have sufficient construction specifications to permit them to be installed with electric light, power conductors and any failure of the cable insulation due to a fault could lead to hazardous voltages being imposed on the thermostat circuit conductors.

The use of the same insulation for circuits up to 600 volts for both AC and DC is acceptable when run in the same cable or conduit, but not for this application.

It is better to see that thermostat wiring run in a separate cable or conduit, or wrapped around the cable or conduit that will supply the unit.
