THHN - PVC underground

[Towzzer]

THHN isn't rated or allowed by the NEC to be used in pvc/rigid underground right? THWN is required

I say this because I just realized that both home depot and lowes only carry THHN

Thhn is mostly dual rated thwn also. Get ahold of a length and read the label on the wire, or else the label on the spool. You will see thwn on the print.
