Burndy SCRULUG Pressure Bar Copper Lug, 1-Hole, Tin-Plated

The Burndy SCRULUG™ pressure bar lug is a mechanical copper lug family built for secure, code-compliant terminations across a wide range of conductor sizes. This 1-hole lug is available in conductor sizes ranging from 1/0 AWG stranded copper through 4/0 AWG stranded copper up to 500 kcmil copper, making it a dependable choice for heavy-gauge power and grounding connections in commercial and industrial electrical systems. Solid copper construction with a tin-plated finish provides reliable conductivity and long-term corrosion resistance in demanding electrical environments, while the pressure bar clamping method allows for a repeatable, high-quality mechanical connection without the need for specialized crimping tools.

Key Features

  • Conductor Range: Available across 1/0 AWG stranded, 4/0 AWG stranded, and 500 kcmil copper conductor sizes, giving installers flexibility to standardize on a single lug design across multiple wire sizes.
  • Durable Construction: Solid copper body delivers excellent electrical conductivity, mechanical strength, and long service life in continuous-duty applications.
  • Pressure Bar Design: Mechanical SCRULUG™ pressure bar provides even, high-pressure clamping across the full conductor surface without nicking or damaging individual strands.
  • 1-Hole Configuration: Single-hole mounting pad simplifies installation on busbars, panelboards, switchgear, and other equipment terminals.
  • Corrosion-Resistant Finish: Tin-plated copper resists oxidation and maintains a stable, low-resistance connection point over the life of the installation.
  • Field-Installable: Mechanical set design allows installation with standard hand tools, without requiring a hydraulic crimping die.
  • Standardized Stocking: Selecting the conductor size option that matches your job lets crews stock one lug family for a broad set of heavy-gauge wiring projects.

Burndy KPA25 – Frequently Asked Questions

1) Do I need a hydraulic crimper to install a Burndy SCRULUG lug?
No. The SCRULUG is a mechanical pressure bar lug, so it sets with standard hand tools and no hydraulic crimping die. That is the main reason crews use it over a compression lug in the field, where hauling a crimper and the right die set to a panel is the bottleneck.
2) Will a SCRULUG lug take a 350 kcmil or 250 kcmil conductor?
Only three conductor sizes are offered in this 1-hole SCRULUG: 1/0 AWG stranded copper (KPA25), 4/0 AWG stranded copper (KPA28), and 500 kcmil copper (KPA34). These are size-specific mechanical lugs, not a range lug, so a 250 or 350 kcmil conductor needs the lug built for that size rather than one of these three.
3) Is this lug rated for aluminum conductor, or copper only?
Copper only. The body is solid copper with a tin-plated finish, and every conductor size option is specified as copper: 1/0 AWG stranded copper, 4/0 AWG stranded copper, and 500 kcmil copper. For an aluminum or a dual-rated AL9CU termination you need a lug specified for that conductor, not this one.
4) Why does the copper lug have a tin plating, and does it matter for my connection?
The tin plating on the SCRULUG copper body resists oxidation, which keeps the contact surface at a stable low resistance over the life of the install. It matters most in damp, outdoor, or corrosive industrial environments and where you are bolting to a plated busbar. Bare copper works electrically but oxidizes at the pad, which is what drives heating at the joint over time.
5) How does a pressure bar lug differ from a set screw lug on fine-stranded cable?
The SCRULUG uses a pressure bar that spreads clamping force across the full conductor surface instead of driving a screw point into the strands, so it clamps without nicking or deforming individual strands. On heavy stranded copper like 4/0 or 500 kcmil that means a more repeatable termination than a bare set screw bearing on one spot.
6) Can I use this lug for a grounding and bonding connection, not just a feeder?
Yes, grounding and bonding is one of the stated applications for the SCRULUG pressure bar lug, along with panelboard and switchgear terminations, busbar and distribution equipment wiring, industrial power distribution, and motor control centers. The 1-hole pad bolts to a ground bar or busbar the same way it lands on an equipment terminal.
7) Is this a one-hole or two-hole lug, and will one bolt hold on a busbar?
It is a 1-hole lug, so a single bolt through the pad secures it. That is standard for panelboard, switchgear, and equipment terminals. If your busbar is drilled on NEMA two-hole spacing, or your spec calls for a two-hole pad to prevent rotation of a large conductor, you need the two-hole version instead of this one.
8) Where do I find the bolt hole size and dimensions for the Burndy KPA34 lug?
Hubbell publishes the manufacturer spec sheet for the KPA34 SCRULUG at https://hubbellcdn.com/specsheet/BRDY-KPA34-SPEC-EN.pdf. That is the document to pull for pad drilling and mounting detail when you are confirming the lug against an existing bolt pattern.
