I have a dilemma. I have a 60M panel with 5 dimmers and I have a 3/4" conduit to my low voltage electric box where all my C-bus terminate to other switches. The switches have only the Cat5 wiring and within code. I want to put 110VAC in the same conduit to power my Clipsal 350ma power supply I want to mount. The USA code for NEC (National Electric Code) will not allow a low voltage wiring under 30vdc and not rated 600v to be in the same conduit as high voltage wiring cannot be with a low voltage wiring without a barrier (Isolation). But the city inspector does not know the term "barrier" and what is needed so they fail / red tag. So my question is, can I just use 2 wires larger 20 gauge 600v rated to communicate for the C-bus and not use the Cat 5 twisted pair for communication. Not on all areas but just in a 8 meter section. I know there was a thread about using 2 stings with salt water for the C-bus which was hilarious. But it means that the simplicity of C-bus just needs basic wiring and for the because of the wide availability of Cat 5 in the market it seems to be the perfect choice. I am not using any remote wires so technically I only need 2 wires to communicate. Thanks Alan Dobbs
