XLPE in conduit?

[rockcrawler]

My Pioneer mini splits came with a 4 conductor XLPE signal cable that says it is for wet and dry applications. Although what I’ve read said it will be fine being exposed to the elements, I’m concerned about how it will actually hold up over time. I cannot find anything that states whether or not it can be run in conduit. I’m considering running the section of the XLPE that will be outside in some liquid tight conduit to provide some extra protection. Is this allowed?

All flexible conduits are subject to the same "protection from physical damage" restrictions as NM (Romex). The minimum that qualifies is EMT or Sch80 PVC conduit.

I'm not sure the OP is using the term "protection from damage" like the code book does. I think it's more of a casual usage like around a weed whacker or a puppy, the sun, etc.

I've looked and I don't see anything that says it's permitted or prohibited, so I'm no help. But I'd do it. XLLP seems like pretty tough stuff from what I've read, and this is outside, lots of the requirements seem to be on interior raceways. Is this going to be inspected? Will anyone care? My vote is yes to liquid tight!

Yes, I'm talking about additional protection from the sun and possible physical damage. Due to my location, It is not subject to inspection, but I still want to make sure my install is completed correctly and safely. I think I will go ahead and use the liquid tight since I cannot find anything that says it’s prohibited. Thanks.

I would put it in at least liquid-tite. Let that take the uv hit instead of the cable.

What you have there is actually type TC, also known as tray cable.

Article 336 of the NEC covers tray cable and 336.10(3) states that it is permitted for use in raceways. Any type of electrical conduit, flex, saltine, etc. is a raceway.

So yes, installing it in liquidtite is allowed.

Thank you very much. Makes me feel better about my decision.

That was my thought exactly.

The jacket on TC is much less rugged than on NM

So yes, installing it in liquidtite is allowed.

It's allowed but TC also has to have protection except in cable trays.

That's TC-ER cable, which is allowed to be run outside of cable tray, when transistioning from tray to tray, or from tray to load equipment. there are restrictions on that, including it doesn't apply in residential applications. in residential applications, you need to use TC-ER-JP cable, which is approved for pulling in structural members. Glad to see the split manufacturers are getting closer to suppling the right wire, the ones I've seen supplied SJOOW.
