    Electrical conduit help


    Ok so I got this little dilemma at work. For a small job we had to run 3/8 poly tube from one end of a building to another. We use regular PVC electrical conduit as a sheath for the 3/8 poly tubing. Now I'm being told by a supervisor that we cannot use the electrical conduit as a shoot for the poly tube and he's telling us that you can only run electrical cables through electrical conduit.
    My question is is this true we can't find any code that says you can only run electrical cables through electrical conduit does anybody have any knowledge on this.

    I've seen pneumatic control tube run through conduit in dangerous locations. It was vented though so no pressure could build within the conduit causing it to burst.

    I could see there being an issue if the tubing you are running carries a flammable gas where a leak would allow build up and possible explosion.

    I've never seen a code saying you couldn't do what you are doing.

    Yeah I actually think I just found my answer. On the Conduit itself it doesn't actually say it's electrical conduit it just says it's plain old conduit which by definition could be used for anything.

    Re: Electrical conduit help

    If you're installing something in electrical conduit, it should be electrical. That is it's intended purpose, the reason it isn't in the code is the code applies to electrical devices, which poly tube is not. "Please don't install air and liquid lines in raceways" should be a no brainer. Your boss is right.

    As Falko said, sometimes people use conduit as a protective sleeve when you near ground level or potential pinch points. There are provisions in the code which allow for atypical installation under "engineering supervision," this is intended for industrial applications where the code is either insufficient or too binary to cover the application. PVC electrical conduit is not intended to be a pressure vessle; the couplings aren't rated for it and the glue isn't rated for it. If you are going to use it as a sleeve, it needs to be vented. Regarding the conduit "not actually saying it's electrical" if the pipe looks like below...it's electrical:

    Electrical conduit, it's a "grey" area...

    Re: Electrical conduit help

    Ok so There is no code that says we cant use this to protect are tubing. Just fround apon as industy practice. But its a big gray area.

    Just a little more info on this job. There are no wiers in this line or near just the 3/8 tubing. It is open on both ends. We used this conduit for its long sweep 90's.

    I donít know much about plumbing code, which is what would apply here.

    Ya he could be right. I'm not saying he's wrong but he is a colossal douchebag. So I assume he is wrong.

    Re: Electrical conduit help

    Is there any pressure in this line? Flammable liquid? If it is just for protection so the flexible tubing is protected against bumps and such I don't think there is any code to stop you from doing it. Plumbing tubing would be more appropriate, but you are not breaking any codes I don't think. You are not technically using it for electrical so our codes wont apply. I bent up and painted some 3/4 emt and use them to hold bird feeders in my back yard, is that against code? Nope!

    Re: Electrical conduit help

    I do not agree with your boss, it is just acting as armor not carrying anything
    Some believe only iron is good for air which is also nuts

    He's the boss though so by definition he is right as long as you have the time and materials to do it his way

    Steel conduit would not droop though

    I ran an entire 40,000 square feet with grey PVC air, water, and coolant emulsion no problem, also made it super simple to add a drop

    If the manufacturer of said conduit list's and labels it's conduit to do other than electrical like pneumatic. Then ya its ok. Never seen pneumatic in conduit but then I'm not looking out for that. Is that what you are running? Isn't the tubing you run rated to be run on its own?

    It's not an pneumatic line it's going to be for a chemical feed. The liner running will be 12 feet in the air away from bumps scratches and Machinery the tubing can perfectly be by itself but again supervisor says do it I do it.

    So its a chemical fluid line run through electrical tubing? I don't see any danger in it. Authority having jurisdiction will have a final call on it. I don't see anything wrong with physical protecting something with a conduit sleeve. Maybe a label on the conduit of its contents? Only thing to consider is the trade of the practice and what it's requirements are. Does this fall under plumbing for example? Probably not. But it may be the better path to take since it is a fluid.

    Ya idk what the hell this guy is thinking. And to top it all off this is all temp. It's for a trial. It's for an Odor Control solution at one of our pump stations. It will most likely be gone within the year anyways.

    Re: Electrical conduit help

    sounds like a waste of money to me. Is this guys the "BOSS" boss. or is there someone higher. Maybe mention you think it's a waste of money.

    or just do it again and get paid twice, things are always easier the second time around?

    Re: Electrical conduit help

    For temporary I wouldn't worry about it. This reminds me of a bar I was in a few months ago in Boston near Fenway. It had an open ceiling and there were several 4" EMT conduits run overhead and dropped down in the bar area. They had a lot of beer on tap. I think these sleeved and concealed the beer lines from kegs to taps. Edit: The Yard House. Thats the place. If thats the case, learn something new everyday. Edit: 2nd edit here but if you look at pictures of the bar and the conduit, that isn't EMT or rigid conduit. I don't know what that is.

    It's defiantly a big East of time and money. But hey he's gotta justify his job some how lol. And it won't be easier the second time around will make damn sure of that
