Cable Type to Lug Cross Reference: THHN, XHHW, DLO, Welding, Battery and Aluminum
One table that maps the cable on the reel to the lug family it needs: THHN, XHHW-2, USE-2, PV wire, DLO, welding cable, battery cable, MV feeder and aluminum. Stranding class decides the lug, not the gauge alone.

DLO Lugs vs Standard Compression Lugs: What Changes and When to Use Each
DLO cable has finer Class I stranding and a larger diameter than THHN or XHHW of the same gauge. A standard compression lug will not crimp it correctly. Here is how to tell the two lug types apart, when each is right, and how to spec them.
