Schedule 80 pvc

[dbacke@roadrunner.com]

Is there any restrictions on installing schedule 80 pvc directly on the surface of the ground, staked and supported to keep it in place. This is located on a hillside, no mechanical damaged forseen.

Thanks.

See Art. 352 for specifics. I don't see anything to prohibit what you are asking. I assume going underground is not possible?

If it's being inspected I guess it would fall under the local jurisdiction if it's a safe installation. And if it's at risk of being damaged or not? :smile:

Do they still sell PVC that is not sunlight resistant ? Also, make sure you figure in expansion.

Would this be considered a legal instalation? Laying the conduit on top of the ground. Would this be OK to do the same under the crawl space of a building? On the same thought could UF cable be installed in the same location without burial?

Yes, the conduit is secured and supported and PVC conduit identified for the use can be installed where subject to physical damage. Schedule 80 PVC is so identified.

Would this be OK to do the same under the crawl space of a building?

Yes.

On the same thought could UF cable be installed in the same location without burial?

No. UF cannot be installed where subject to physical damage.

The quote is from the orignal post, again would UF cable be OK to use as no damage is forseen

. . . again would UF cable be OK to use as no damage is foreseen

The "foreseen" part is what I have a problem with. :smile:

I can't see an AHJ buying that. It is outside and above grade and in my opinion it is exposed to physical damage. If you put the UF in a crawl space, then some might agree that it is not subject to physical damage, but I would not be among them. It is my position that if you can see it, it is subject to physical damage.

That is a very broad and tough stance in regards to what is subject to physical damage.

I wouldn't want to put in a exposed run of PVC on the ground on a hill. I'd have to really look at what that hills use could be. Kids sledding. Motorcycles. Four wheelers. Or is this a hill on a commercial site that would not be expected to be used for recreation?

I've never seen this for a permanent install, but I've seen it for temporary job site office trailers.

The code does not give any guidance so that is my interpretation of what the term means. I would even suggest that in many cases, the electrical installation is subject to physical damage even when it is not visible.
