question on direct burial conductors
want to direct bury individual #6 copper conductors, NOT MULTIWIRE CABLE. which wire type is listed for direct burial? i know xhhw, for example is listed for dir bur in larger sizes. will direct burial listing always be printed on the insulation? i'm assuming "wet" listing is not the same (or acceptable) as direct burial necessarily, right? i checked the nec, and i'm guessing that "direct burial" is something i'll have to find on the wire, not in the wire characteristics table.

You are probably familiar with UF and USE as a multiconductor cables, but they are also sold as individual conductors. These are rated for direct burial, but I know of no other conductor types that are so rated.
The NEC does not show XHHW as rated for direct burial.
And you are right in that "wet" does not imply suitability for direct burial.

Chances are that what you are looking at has additional ratings other than XHHW which allow it to be direct buried. XHHW by itself does not. It is common for wire to have multiple ratings.
