Never even considered direct burial cable to be honest.
I'm saying that what you put in the conduit must be direct burial cable.
Everything installed below grade, even in conduit and innerduct HAS to be suitable for direct burial. That conduit and innerduct will fill with water no matter how you think it won't. It's a common misconception by greenhorns to think they can install UG conduit and just pull "indoor" cable and it will last. Ain't gonna happen.
