Panduit LCA6-56F-L One-Hole Compression Lug, #6 AWG, 90° Tongue, 5/16" Stud
The Panduit LCA6-56F-L is a one-hole, standard barrel compression lug from the Pan-Lug™ series, engineered for #6 AWG copper conductors terminated at a 90° tongue angle onto a 5/16" stud. At 1.15 inches overall length and sold in 50-piece packages, the LCA6-56F-L (often searched as LCA6 56F L) is the right pick for panel-level grounding, power distribution, and equipment bonding runs where a right-angle termination clears adjacent hardware without forcing the wire into a sharp bend radius.
Overview
The Pan-Lug™ compression lug family targets professional electrical and telecom installations that need verified, inspectable connections — not just a crimped termination that disappears inside a panel. The LCA6-56F-L carries UL Listing to 486A-486B and NEBS Level 3 certification, covering both the electrical performance standard for wire connectors on copper conductors and the telecom-infrastructure survivability specification required by carriers and data center operators. The 90° tongue geometry reduces routing conflicts in tight enclosures: instead of running wire straight through and bending it inside the panel, the conductor approaches horizontally and the lug face lands flat against the stud.
Key Features
- Tin-Plated Barrel: The tin finish on the copper barrel passivates the mating surface, slowing oxidation at the conductor interface. In humid or mildly corrosive environments — mechanical rooms, outdoor-rated enclosures, coastal installations — this directly extends the service life of the joint without requiring anti-oxidant compound.
- Color-Coded Barrel: The barrel color identifies wire gauge at a glance during installation and inspection. In a multi-gauge panel where several lug sizes are staged, color coding eliminates the crimping-the-wrong-lug mistake that causes field failures and rework.
- Inspection Window: The barrel window lets you visually confirm full conductor insertion before crimping — no guessing whether the wire seated fully. This is a quality-control feature that matters most on high-density termination runs where mis-seating one conductor in fifty can take hours to diagnose after energization.
- 90° Tongue Angle: The right-angle geometry exits the stud perpendicular to the wire run, which is the correct orientation for panels where conductors enter from the side and studs face outward. This eliminates forced bends that stress insulation and violate minimum bend radius for the conductor.
- 5/16" Stud Hole: Sized for standard 5/16" hardware common on bus bars, equipment ground terminals, and rack PDU bonding points. Match this before ordering — a mismatched stud hole is the most common reason lugs get returned on commercial projects.
- UL Listed to 486A-486B: UL 486A-486B is the governing standard for wire connectors and soldering lugs for copper conductors. Listing means the connection design, materials, and crimp tooling have been independently verified for electrical continuity and mechanical retention — required by NEC-based inspection regimes and most government and carrier facility specifications.
- NEBS Level 3: NEBS Level 3 is the full telecom equipment survivability rating, covering thermal cycling, vibration, seismic zone 4, and ESD. If you're terminating in a central office, carrier hotel, or hardened data center that specifies NEBS compliance, the LCA6-56F-L meets the requirement — most commodity lugs do not.
- 50-Piece Package Quantity: Stocked in 50-piece packs — practical for project quantities without committing to a full carton. For multi-panel jobs or staged deployments, this pack size matches common per-panel lug counts on #6 AWG runs.
Integration & Compatibility
The LCA6-56F-L terminates #6 AWG copper conductors only — the barrel is sized for this gauge, and using it on undersized wire produces a mechanically deficient crimp regardless of torque. The 5/16" stud hole fits standard 5/16"-18 and 5/16"-24 threaded hardware. Crimping requires a compatible compression die set for the Pan-Lug™ LCA series; consult the Panduit die cross-reference for your tool platform. The 1.15" overall length sets the minimum clearance envelope from the stud centerline to the wire exit point — verify this fits the lug-to-adjacent-hardware spacing in your specific enclosure before committing the run. The tin-plated barrel is rated for bare copper conductors; tinned-copper conductors are compatible. Aluminum conductors require a different lug series.

Frequently Asked Questions
Q: What wire gauge does the LCA6-56F-L accept?
A: The LCA6-56F-L is sized for #6 AWG copper conductors only. Using it on smaller-gauge wire produces an inadequate crimp. Aluminum conductors require a different lug series.
Q: What stud size does the LCA6-56F-L fit?
A: The lug is drilled for a 5/16" stud hole, compatible with standard 5/16"-18 and 5/16"-24 threaded hardware commonly found on bus bars and equipment ground terminals.
Q: Is the LCA6-56F-L NEBS Level 3 certified?
A: Yes. The LCA6-56F-L meets NEBS Level 3, which covers thermal cycling, vibration, seismic zone 4, and ESD requirements — the full survivability specification for central office and carrier-grade telecom environments.
Q: Is the LCA6-56F-L UL Listed?
A: Yes. It is UL Listed to UL 486A-486B (File #E52164) for wire connectors and soldering lugs on copper conductors, satisfying NEC inspection requirements and most government and carrier facility specs.
Q: How many lugs come in a package?
A: Each package contains 50 pieces of the LCA6-56F-L.
Q: What is the overall length of the LCA6-56F-L?
A: The overall length is 1.15 inches. Verify this fits your enclosure's lug-to-adjacent-hardware clearance before committing the run.
The LCA6-56F-L is one of those components that looks trivial on a BOM until a panel fails inspection because someone subbed in an unlisted lug. The NEBS Level 3 rating combined with UL 486A-486B listing is the combination that satisfies both the electrical inspector and the carrier's infrastructure team — I've seen plenty of installations where the lug was the single non-compliant item that held up commissioning.
Technical Highlights:
- NEBS Level 3: Full telecom survivability — seismic zone 4, thermal cycling, vibration, ESD — not just the partial NEBS Level 1 or 2 that commodity lugs sometimes claim. Required by spec in carrier hotel and central office environments, not optional.
- Inspection Window: Visual confirmation of full conductor seating before crimping. On a 50-lug termination run, this prevents the one bad crimp that causes a resistive joint and localized heating — a failure mode that doesn't show up at initial energization but develops over months.
- Tin-Plated Barrel: Passivated surface slows galvanic oxidation at the copper-to-copper interface. In mechanical rooms or outdoor-rated enclosures where temperature cycles daily, this is meaningful — bare copper lugs in the same environment develop oxide layers that increase contact resistance over time.
Deployment Considerations:
- The 90° tongue angle is correct when conductors enter the panel laterally and studs face forward — if your run geometry is straight-through (conductor and stud in-line), you need the straight-tongue variant, not the LCA6-56F-L. Check the tongue angle against your enclosure drawing before pulling wire.
- Crimping the LCA6-56F-L requires a compatible Pan-Lug™ die set for the LCA series — using a generic die from a different lug family risks an under-compressed barrel that passes visual inspection but fails pull-test. Verify die compatibility with the Panduit cross-reference before the job starts.
For carrier infrastructure, data center ground grid work, or any NEC-inspected commercial panel where #6 AWG terminates at 5/16" hardware in a right-angle routing path, the LCA6-56F-L is the correct spec — particularly where the project calls out NEBS Level 3 compliance by name.
