Is THWN listed for use underground?
That is an interesting point.
Can I ask a couple of questions
Why use a cable if the raceway runs form point to point?
Is it allowed to run SE cable in a complete raceway? Not just a short section for physical protection.
The 2002 NEC did not allow NM cable in a complete raceway, there is a change in 2005 to allow this.
