I've read HP Richter's Practical Electrical Wiring, and in some places it says low voltage and high voltage wiring should never be in the same elect. box or conduit. In others it seems to say that although low and high voltage wiring should not be in the same box, it is ok to do so.
I'm adding controls for a multi-zone heating system, and need 110V, 24V and control wiring in the same box. This is for a pump relay (24V coil, 110V load), a 24V transformer, thermostat wires, and wires for boiler control and thermal detectors. I plan on labelling both the wires and the conduit locations. I do not see a way to put a metal barrier up between the low and high voltage wiring in the box, since the relay takes both. So the question is, what does the electrical code say about this kind of mix of voltages - what do I need to do to be in compliance?
