Is Tray Cable acceptable for Residential use?


I'm trying to stick with one type of wire/cable for feeding a sub-panel 125' away from a 60amp 2-pole in my main panel. Something that can be used within walls, in a crawl space, and direct buried. This is what I am considering using-

Any suggestions/comments are appreciated.

Thanks!

USE-2 meets all the requirements and is probably cheaper and easier to find.

USE is not allowed for interior wiring. Is USE-2 allowed?

The new USE is dual rated as RHW or RHH also. Still gotta pipe it inside though.

338.12(B) specifically refers to USE, not USE and USE-2, so I assumed the prohibition did not apply to USE-2. However, the explanatory text in the 2011 handbook says it does. Apparently the basis for this is that USE and USE-2 are not required to have flame retardant jackets.

Maybe the only jacket cable type that could be used for this installation would be UF?

How about using SE-R from the main panel through the crawl space and then splicing into USE-2 in an LB on the outside of the house and from there take the USE-2 to the panel in the garage? If this works, can the USE-2 be inside conduit within the walls? It would need to be piped about 7' in the same exterior wall it came in, up to the panel. I can run the conduit up the outside of the wall and into the panel, but I would rather use the pvc that was put in the foundation specifically for this. Both cables would #2 AL with a #4 ground.

Do not splice in the LB. There isn't enough room.

Can some kind of junction box be used to splice these cables?

OK, after some reading it seems I need to figure out the box fill calculation for anything larger 6 awg being spliced in a junction box. The calculation being based on the trade(?) size of the conduit being used and whether it is a straight or angle pull. Straight times 8 and angle times 6. If it is an angle pull/splice using 2" pvc conduit, I would multiply 2 x 6 and get a 12" x 12" junction box? Am I even in the parking lot of the ball park with this???

Of course you can. It would be the "big goofy boxes" that you made reference to.

I now know there is no one perfect wire or cable that can be used in any/all/multi installations/applications. It seems odd that there isn't though........

What two types of cables would you like to splice together and how are they going to be ran?
