Panduit A6-14R-C Pan-Lug™ Battery Cable Lug

The Panduit A6-14R-C Pan-Lug™ compression lug is engineered for high-current battery cable and DC power terminations where pull-out strength and long-term reliability are non-negotiable. Designed for 6 AWG wire and 1/4" stud applications, this tin-plated copper lug handles UPS battery banks, emergency power circuits, renewable energy inverters, and datacenter backup systems. The flared wire entry simplifies insertion during fast turnarounds, while embossed wire sizing prevents mix-ups on multi-gauge installs. Sold in 100-piece packs, the A6-14R-C is cULus listed to UL 486A-486B and meets US Military wire pull-out specifications—the compliance baseline for commercial and critical-infrastructure DC terminations.

Key Features

• 6 AWG wire capacity with 1/4" stud size for UPS, battery, and DC power circuits
• Tin-plated copper construction resists corrosion in high-humidity mechanical rooms and outdoor enclosures
• Flared barrel entry speeds wire insertion during high-volume terminations
• Embossed wire size marking eliminates gauge confusion on mixed-size battery banks
• cULus Listed to UL 486A-486B for power applications in US and Canada
• Meets US Military wire pull-out specifications for high-vibration and mission-critical installations
• 100-piece packaging reduces per-termination cost on datacenter and renewable energy projects

The A6-14R-C uses a compression barrel design that forms a gas-tight mechanical bond when properly crimped with a hex die tool—eliminating the cold-flow creep and joint loosening common with set-screw or bolted lugs. Tin plating over high-conductivity copper provides dual benefits: it prevents oxidation at the crimp interface (critical for maintaining low contact resistance over 10+ year service life) and offers inherent lubricity during the compression stroke, reducing die wear and ensuring uniform barrel deformation. The 1.47" overall length provides adequate insulation clearance for NEC Article 480 battery installations, while the 1/4" stud bore fits standard battery terminal posts, inverter bus bars, and DC disconnect lugs without adapter hardware. Each lug is embossed with wire size, a small detail that prevents mis-termination errors when installers are working across 4 AWG to 2/0 battery strings on the same rack.

This lug is a workhorse in datacenter UPS installations, where VRLA or lithium battery strings require hundreds of terminations per cabinet and every joint must meet calculated fault-current ratings. Integrators also specify the A6-14R-C for solar combiner boxes, wind inverter DC inputs, electric vehicle charging infrastructure, and telecom central-office 48 VDC plants—anywhere DC current exceeds 50 amps and termination reliability directly impacts uptime SLAs. The 100-count packaging aligns with typical single-rack battery-string quantities (40-60 cells requiring 80-120 lugs), reducing procurement overhead and ensuring batch consistency across an entire installation.

cULus dual-listing to UL 486A-486B qualifies the A6-14R-C for inspected commercial and industrial power systems in both US and Canadian jurisdictions, eliminating the cross-border sourcing headaches common on multinational datacenter builds. Military pull-out spec compliance ensures the crimp joint survives seismic events, HVAC vibration, and thermal cycling without strand slippage—the failure mode that causes cascading DC arc faults in battery cabinets. For integrators spec'ing to NFPA 70, NFPA 111, or IEEE 1635 battery standards, Panduit's published torque and die specifications provide the documentation trail AHJs expect during plan review and final inspection.
