Panduit A2/0-56RC-C 2/0 AWG 5/16" Compression Lug 100pk

Panduit A2/0-56RC-C 2/0 AWG Compression Lug 100-Pack

The Panduit A2/0-56RC-C Pan-Lug™ compression lug terminates 2/0 AWG battery cables to 5/16" stud connections in UPS installations, backup power systems, and DC distribution. Tin-plated copper barrel construction delivers corrosion-resistant terminations that meet cULus standards for commercial power applications. Each lug carries embossed wire size markings and ships in contractor-grade 100-count packaging for battery string builds and data center power projects.

Key Features

• 2/0 AWG wire capacity with 5/16" stud hole for battery terminal and bus bar connections
• Tin-plated copper construction resists oxidation in battery rooms and outdoor enclosures
• Flared barrel entry guides 2/0 stranded copper during crimping—reduces prep time on large wire
• Embossed wire size marking on each lug prevents mix-ups in multi-gauge installations
• cULus Listed to UL 486A-486B for power applications—required for AHJ signoff on commercial UPS work
• Meets US Military wire pull-out specifications for high-vibration and critical-load applications
• 100-pack bulk packaging supports battery string projects without mid-job reordering

Material & Compliance Engineering: The tin-plated finish maintains low contact resistance across temperature swings and humidity common in battery rooms. Bare copper lugs oxidize within months in VRLA environments, increasing connection resistance and heat at termination points. Tin plating extends service life to match typical UPS battery replacement cycles (3-5 years). The high-conductivity copper barrel handles full-rated current without derating. UL 486A-486B listing confirms the crimp die profile, pull-out strength, and temperature rise meet National Electrical Code requirements for commercial installations—inspectors will ask for Listed components on permitted UPS and generator work.

Installation & Tooling: This compression lug requires a hex crimp tool with 2/0 AWG die (Panduit CT-2000 series or equivalent). The flared entry口 accommodates the 0.365" diameter of 2/0 stranded copper without pre-forming the conductor. Strip length is 0.75" from the barrel base. Proper crimp produces a cold-weld joint with pull-out strength exceeding the wire's tensile rating—critical for battery strings where thermal cycling and charge/discharge vibration stress terminations. The 5/16" stud hole fits standard battery post hardware and bus bar studs up to 0.31" diameter. Torque to battery or bus bar manufacturer specs (typically 10-15 ft-lbs for 5/16" stud applications).

Typical Deployments: Security integrators use these lugs to terminate DC feeder cables from UPS battery cabinets to surveillance system power distribution. A single 48V battery string for an enterprise NVR and PoE switch load might use 12-16 lugs across series connections and bus bars. Data center and telecom installations deploy them on -48VDC distribution buses and rectifier outputs. The 100-pack count aligns with battery string projects: a 20-battery UPS cabinet requires 40 lugs (positive and negative on each battery), leaving spares for field corrections and future expansions. The embossed size marking prevents accidental use of wrong-gauge lugs during multi-phase builds where 1/0, 2/0, and 4/0 wire coexist.

cULus dual-listing covers installations under both US (NEC) and Canadian (CEC) electrical codes. Military pull-out spec compliance makes these lugs suitable for government and defense projects requiring MIL-grade terminations. Use Panduit A2/0-56RC-C compression lugs where UPS battery installations, backup generator DC circuits, or solar/battery storage systems demand Listed terminations that survive 10+ year service life in critical power infrastructure.
