Panduit A2-14R-C 2 AWG 1/4" Stud Compression Lug

Panduit A2-14R-C 2 AWG Battery Cable Compression Lug — 1/4" Stud

The Panduit A2-14R-C is a professional-grade compression lug designed for terminating 2 AWG battery cables and power conductors to 1/4-inch stud connections. Part of Panduit's Pan-Lug™ family, these tin-plated copper lugs deliver low-resistance, long-term electrical performance in UPS systems, battery banks, solar installations, and industrial power distribution. The flared barrel entry simplifies wire insertion during high-volume terminations, while the embossed wire-size marking ensures field crews select the correct lug every time. Supplied in 100-piece contractor packs, the A2-14R-C is cULus listed for power applications in both the US and Canada and meets stringent US military pull-out specifications for mission-critical reliability.

Key Features

• 2 AWG wire capacity with 1/4-inch stud mounting hole for battery, UPS, and power distribution applications
• Tin-plated copper barrel resists corrosion and maintains low contact resistance over decades of service
• Flared entry simplifies conductor insertion and reduces prep time on multi-termination jobs
• Embossed wire-size marking eliminates guesswork and prevents incorrect lug selection in the field
• High pull-out strength design exceeds US military specifications for vibration and mechanical stress
• cULus listed to UL 486A-486B for use in branch-circuit and feeder power applications
• 100-piece contractor pack provides consistent inventory for large battery-bank builds and solar arrays

Battery cable terminations demand more than generic hardware-store lugs. The Panduit A2-14R-C employs high-conductivity electrolytic copper with a controlled tin-plating process that prevents oxidation at the crimp interface and stud contact point. The barrel's internal geometry is engineered for uniform compression across the full wire bundle, ensuring gas-tight contact between each strand and the lug wall. This eliminates hot spots and voltage drop that plague improperly crimped connections. The 1.84-inch overall length provides ample barrel depth for full wire seating, while the flared entry cone reduces the risk of strand kickback during crimping. In high-vibration environments—generator enclosures, mobile power systems, transportation applications—the lug's mechanical grip meets military pull-out standards, preventing the conductor from backing out under shock loads that would compromise lesser terminations.

Integrators building out battery backup systems for access control panels, surveillance NVRs, fire alarm networks, and critical IT infrastructure rely on the A2-14R-C for the negative and positive bus connections that tie individual cells into series strings. Solar installers use these lugs to land array home-run conductors at combiner boxes and inverter DC terminals. Data center crews terminating 2 AWG feeder taps from main distribution panels depend on the cULus listing and Panduit's third-party test documentation to satisfy AHJ inspections and insurance underwriter requirements. The embossed wire size prevents mix-ups when a job site stocks multiple lug sizes, and the 100-count packaging aligns with the termination count on mid-size battery banks (50 cells = 100 terminations) and solar combiner runs. Every lug ships with full traceability for projects that require material certifications and compliance records.

Panduit's Pan-Lug compression terminations have anchored mission-critical power infrastructure since the 1960s, delivering the consistent quality and third-party certification that commercial integrators, industrial electricians, and solar contractors build their reputations on. The A2-14R-C brings that same field-proven reliability to 2 AWG battery and power-distribution work—tin-plated for corrosion resistance, flared for fast installation, embossed for error-proof selection, and tested to the pull-out standards that keep connections intact when equipment racks shake, generators fire up, and thermal cycling stresses every joint in the system.
