One-Hole vs Two-Hole Compression Lugs and NEMA Hole Spacing
One hole or two is decided by the pad, not the conductor. Where each is used, the NEMA hole spacings that matter (1 inch on 3/8 bolts, 1-3/4 inch on 1/2 bolts), ground bar patterns, and the mistakes that get lugs rejected.

Long Barrel vs Standard Barrel Compression Lugs: Which to Specify
Long barrel lugs take two crimps and more conductor engagement; standard barrel lugs fit where space is tight. When each is the right spec, what stays the same, and why short barrel is just another name for standard.

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.
