This isn't the main reason running low and high voltage through the same conduit is not code compliant though.

The reason you don't mix low/high in the same raceway is because if exposed low/high voltage conductors come in contact with each other, the low voltage cable has a much higher chance of catching fire.

I didn't think of that. It makes sense. I did think about the low voltage wire picking up enough voltage from induction to damage equipment.
