Burndy YA25L4-BOX – Frequently Asked Questions
1) What wire sizes do Burndy HYLUG copper compression lugs cover?
The HYLUG copper terminal lugs run from 8 AWG up through 500 kcmil across the catalog numbers offered: YA8CL, YA6CL, YA4CL, YA2CL, YA1CL, YA25 (1/0), YA26L (2/0), YA27L (3/0), YA28 (4/0), YA29 (250 kcmil) and YA34 (500 kcmil). The core spec range called out for the long barrel tin-plated series is 1/0 AWG through 4/0 AWG. Pick the catalog number that matches the conductor you are terminating; these are sized per conductor, not adjustable.
2) Are these Burndy lugs good for aluminum conductor, or copper only?
Copper only. The HYLUG YA series here is a copper barrel with a tin-plated finish, and the conductor material it is built for is copper. If you are terminating aluminum, you need a lug rated AL9CU or an aluminum-bodied compression lug instead - putting bare aluminum into a copper-only barrel is not a listed connection.
3) Will a single-hole straight tongue lug land on a two-hole NEMA pad?
No. These HYLUG terminals have one bolt hole and a straight, standard tongue, so they land on a single-stud or single-bolt pad. A NEMA two-hole pad with 1-3/4 inch center spacing needs a two-hole lug. For bus bar and switchgear pads specified as two-hole, order the two-hole version of the catalog number instead of this one.
4) Can I use these Burndy HYLUG lugs on medium voltage cable terminations?
The rating spans 600V up to 35 kV, so the HYLUG copper terminal covers standard 600V panel and switchgear work as well as medium voltage terminations up to 35 kV. The insulation system around the termination, not the lug, is what usually governs on MV work.
5) Why choose a long barrel lug over a standard barrel one?
The long barrel gives you more contact length on the conductor and room for two crimps instead of one, which is what you want on high-current feeders, motor connections and grounding runs where pull-out matters. The barrel entry is chamfered so a fully stranded 4/0 conductor pushes in without birdcaging. If you are on a short landing with tight bending room, a standard barrel is the easier fit.
6) Does the tin plating matter in a damp or outdoor enclosure?
Yes, that is what it is there for. The barrel is copper with an electro-plated tin finish that slows oxidation at the conductor interface and at the bolted pad, so it holds conductivity better in damp basements, exterior switchgear and substation work than bare copper. It also makes the lug a cleaner match against tin-plated bus.
7) Are these Burndy lugs sold individually or by the box?
Most of the HYLUG catalog numbers here carry a BOX suffix, such as YA4CL-BOX and YA6CL3-BOX, meaning they come as a boxed quantity rather than a single piece. A few, like YA25, YA28 and YA34, are listed without the box suffix. Check the suffix on the catalog number you are ordering if you only need a handful.
