Cored Hole Conduit necessary?

[W@ttson]

I have a specialty multiconductor cable like this one: https://www.okonite.com/media//catalog/product/files/4-8.pdf

I will have a hold cored through a 5 ft concrete wall. The core will be super smooth. There is dirt on both sides of the hole. Is there anywhere that requires the cable to pass through the concrete in conduit? Or can I use the smooth concrete cored hole as a conduit?

I dont see any issue running it right thru with no additional conduit. I might put some sort of bushing or extra protection around it at each end in case it gets pressed up against the corner of the hole by backfilling or settling.

Yeah, I was thinking about grouting in a big bell ends.

Is this cable listed for use without a raceway?

 

[W@ttson]

Yes, it is. I just wasn't sure if there was some provision in the NEC that says "where susceptible to damage" or "direct burial cables shall not pass through holes in concrete without sleeves" or something like that .

No such requirement for cored holes so sounds like you're good to go.
