THHN in yard work conduit

[danickstr]

Is THHN allowed to be pulled underground through SCH 80 PVC and up into bellboxes? Or is THWN required.

Most thhn is also rated thwn

You need a conductor with a 'W' in it.

XHHW, THW, THWN etc.

But I also agree with walkerj that most if not all THHN is dual listed as THWN......most likely THWN-2.
