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.

Short answer, no.

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?

The new stuff is dual rated. See above post.

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.

MisterSteve 02-20-2012 08:51 PM

So is splicing even an option?

MisterSteve 02-20-2012 10:18 PM

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

MisterSteve 02-20-2012 10:58 PM

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. :whistling2:

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........

rrolleston 02-20-2012 11:04 PM

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