Hopefully someone from the Chicago area can help with this question as the electrical codes here are a bit different/strigent than the rest of the country.

I want to run 12v lighting in a home theater I'm building.

Does low voltage need to be in conduit or can it be left out?

I would check with the zoning folks about the need to have this wiring in conduit. I have run, accent lighting wiring, intercomm wiring, speaker wiring, cable TV and other low voltage wiring in residential and commercial with out needing to put it in conduit, but scince the cow kicked over the latern, Chicago has strict fire laws, so check with them. If you need to put this in conduit, check to see if it requires metal or plastic. Also put an addition pull string in while you have the chance, it may come in handy in the future.

The NEC, prior to the 2005 edition requires that concealed low voltage wiring for lighting be installed as a chapter 3 wiring method. What this means is, low voltage wire cannot be used, a line voltage method is required.

Since Chicago does not allow non-metallic sheathed cable, I'm guessing that you'll need a metal encased cable or EMT.

A call to the building department on Monday morning will get you the definitive answer.

We had data/voice cabling installed in our Chicago office a few years ago and were told that hard conduit was required from the outlet all the way to the equipment. We are about to do the same in a much larger space.

Does anyone know of an online reference where I can further explore the details of this requirement (i.e grandfather laws, etc.)

Thanks.
