Panduit A6-38R-C Pan-Lug™ 6 AWG 3/8" Compression Lug

Battery backup and UPS installations demand terminations that won't fail under vibration, thermal cycling, or years of standby duty. The Panduit A6-38R-C delivers field-proven reliability for 6 AWG conductors in critical power applications — from data center battery strings to emergency lighting inverters. Tin-plated copper construction ensures low contact resistance and corrosion immunity, while cULus listing and military-spec pull-out strength give you code compliance and mechanical confidence in a single termination.

Key Features

• 6 AWG wire capacity with 3/8" stud size for standard battery posts and bus bars
• Tin-plated copper barrel and pad for superior conductivity and corrosion resistance in battery environments
• cULus Listed to UL 486A-486B for power applications in US and Canada installations
• Meets US Military wire pull-out specifications for high-vibration and mission-critical applications
• Flared barrel entry eases wire insertion during field termination
• Embossed wire size marking prevents installation errors in multi-gauge battery banks
• 100-piece contractor pack reduces per-termination cost on UPS and power distribution projects

The A6-38R-C uses a seamless copper barrel with integral pad, tin-plated to MIL-DTL-15081 standards. Unlike mechanical set-screw lugs that rely on point contact, proper compression creates a cold-weld bond across the full barrel circumference — critical when terminating valve-regulated lead-acid (VRLA) or lithium iron phosphate (LiFePO4) battery strings where a single high-resistance joint can cascade into thermal runaway. The 3/8" stud hole accommodates standard battery terminal posts and NEMA-spec bus bars without oversizing; the 1.47" overall length provides adequate creepage distance for NEC 110.26 working clearance in panelboards and junction boxes. Panduit's embossed size marking remains legible even after years of battery off-gassing exposure — a small detail that prevents costly field errors when an integrator returns to add capacity to an existing string.

You'll deploy the A6-38R-C anywhere 6 AWG copper conductors land on battery terminals, inverter inputs, or DC distribution blocks. Data centers spec these for 48V battery cabinet interconnects; security integrators use them to terminate backup power feeds to access control panels and PoE injector battery inputs. The flared entry becomes critical when working in tight enclosures — think vertically-mounted battery racks where you're crimping overhead with limited swing radius. The cULus dual-listing covers both NEC (National Electrical Code) and CEC (Canadian Electrical Code) installations, so cross-border projects or national rollouts don't require separate termination inventories. Military pull-out compliance isn't just for DoD work; it translates directly to mechanical reliability in commercial applications with HVAC vibration, seismic activity, or heavy forklift traffic in the same space.

The 100-count packaging aligns with typical UPS install scope — a 12-battery 48V string requires 24 terminations (positive and negative per battery), so one box handles two strings with spares for future expansion or field rework. Unlike offshore compression lugs that list a gauge range (e.g., "4-6 AWG"), Panduit's dedicated 6 AWG barrel ensures full compression contact area and eliminates the "undersized conductor in oversized lug" failure mode that voids UL listing. For integrators managing inventory across multiple project types, the A6-38R-C represents the standard medium-duty battery termination — scaled between the A4-38R-C (4 AWG for larger inverter strings) and the A8-38R-C (8 AWG for lighter backup loads).
