I need to place the outlet for my projector and I am worried once more about interference from being to close to my video or audio cables...

here is the situation:

If you look at the image and make your lines perpendicular to the joists, then straight left would be the front of the room. The conduit is roughly right in the middle of the room, between the 2 side walls...

I am trying to decide if I should put the outlet next to the conduit there, or is it a much better idea to put it on the other side of the HVAC duct that is there. That takes you backwards away from the screen. The only thing I was thinking is the joists are some 14" apart, and depending on how it is mounted, the projector would extend back a little, but I want to avoid having the power string some 6-8 inches to the projector just because I dont know how clean it would be. Would it be bad to have it situated near the conduit there?

Or actually I might be able to place a 2x4 between the joists allowing me to attach the box to that which would let me the have the outlet somewhere in the middle between the joists...

Just another one of those little things that I think I am over thinking.

I wouldn't worry about it, as long as you are 6 inches away and keep your cross overs at 45 degree angles you should be fine. That is the purpose of shielding in the cables and they are much better today than in the old days. Mine runs to the same box (from different directions, but they are about two inches apart at the box and there are no interference problems.

...as long as you are 6 inches away and keep your cross overs at 45 degree angles you should be fine....

I think that should be at 90 degrees!

It looks like you already have a 20A run near the conduit (the yellow piece of Romex). I'd put my box around where the Romex crosses the joist and you already have the holes drilled (assuming that your electric is coming from the same place).

yes, of course 90 degrees would be ideal, but anything 45 degrees or more is fine.

That romex actually runs for my lights...but from what I am gathering, I figure I will do the 2x4 method where I keep it some 6" away. I guess my biggest thing is I want to keep everything sort of close in this area because I dont want the wires coming from all over the place to plug in to the projector. If they are in close proximity, I can keep things looking much cleaner and the all important WAF will definitely be much much higher than if the electrical was strung across the ceiling.

if your concerned about interference use steel conduit. Besides an inspector will make you take out that conduit that is already installed if its not rated for electrical use.

The is no electrical in that conduit, it is all low voltage video

your low voltage video is considered a class2 or class3 electrical circuit according to the NEC which means it needs to be ran open air or in listed conduit.

Where in the NEC? I can't find any place where it says that low volt is considered class 2 or class 3.

Actually the code doesnt consistently define what a low voltage circuit is. For those wires to be installed in wall (or ceiling) they should be cl2 or cl3 rated. Its too hard for me to tell by the picture. The circuit rating would be determined by the power supply secondary in the source equipment. .ie 120vac/12vdc or 7v or 5v depending on the source. Initially I was looking at 640.9 (C) but this article is for audio equipment. I guess my only question would be is that conduit listed for electrical use? If not, section 110.3 B applies and this would be a violation. But then again an inspector might not care.

If it's in separate conduit runs space 6" or so apart it'll be fine.
