DIYbanter - View Single Post - use conduit as neutral in low-voltage system?

Hi, I'm planning a remote control lighting system. There are two parts
of this system: 1) the low-voltage 24VAC signalling side and 2) the
120VAC power side. Each side runs in its own separate thickwall
conduit.

I understand that conduit can be used as the grounding (green)
conductor in many cases, but my question concerns NEUTRAL (white) in a
low voltage system.

Can I use the conduit as NEUTRAL (white) on my 24VAC low-voltage side?
If not why not?

This is probably a matter of local code. For instance, some low voltage
systems have lights that hang from 2 exposed wires. Sometimes those
wires have to be insulated, sometimes they do not.

Im going to bet though that the answer is NO since no electrician would
expect the conduit itself to be energized. It could be dangerous for
folks doing work. Plus other reasons I can think of.
