XLPE USE-2 ratings

[juke]

I was wondering if anyone has used USE-2 XLPE to come from a meter pedestal into the panel in a residential home? I left my code book on the jobsite. Is this legal?

USE can not enter a building.

Unless there is dual rating of the USE it is not allowed inside a building. I don't even see XLPE as a NEC acceptable conductor.

XLPE - Cross-linked polyethylene, which shows up in an XHHW-rated conductor and some medium voltage cables.

What does it mean when you say it shows up. Are you saying xlpe is the same as xhhw. I realize that use-2 and xhhw are recognized by the nec. I am not sure where xple comes into play.

use i think is dual rated rhhw or rhw and as such can enter a house right?

It needs a flame retardent jacket to enter a structure.

XLPE is a type of plastic, such as PVC is another. XHHW has an insulation made of XLPE. THHN has an insulation made of PVC with a Nylon coating.

It's legal as long as it has a dual rating USE-2/XHHW. Just having XLPE printed on the jacket does not qualify.

I agree, it must be dual rated to enter a building. I have some USE / RHW in my truck that would qualify.

Just wrap it around the wire a few times and you're good. Don't forget about raceway fill.

Thanks Smart. That was a good explanation.
