Panduit Terminal Connector – Two-Hole Long Barrel Lug with Window

Designed for reliability in demanding grounding applications, the Panduit Terminal Connector is a precision-engineered two-hole, long-barrel lug with a window that makes electrical terminations visible and verifiable. Sized for #10 AWG conductors, with a 1/4" stud hole and 0.75" hole spacing, this lug delivers a secure, code-compliant connection in data centers, telecom closets, and industrial environments. Built to meet stringent industry standards, this connector integrates seamlessly with standard mounting hardware and is available in variations that accommodate different NEMA hole sizes and spacings to suit diverse panels and grounding needs. Whether upgrading a rack, assembling a power distribution unit, or reinforcing a building’s network grounding system, this Panduit terminal connector provides long-term performance, safety, and ease of inspection.

• Two-hole, long-barrel design with inspection window: The two-hole configuration combined with a long barrel provides a robust termination geometry that ensures deep conductor seating and a secure clamp. The window adds a practical advantage by allowing immediate visual confirmation of proper seating and clamp engagement, reducing guesswork during installation or maintenance. With a #10 AWG conductor capacity and a 1/4" stud hole, this lug aligns with standard grounding hardware found in data centers, telecom facilities, and industrial panels. The 0.75" hole spacing supports typical mounting footprints, enabling straightforward replacement and retrofit in existing assemblies while preserving reliable electrical contact over the life of the installation.
• Versatile compatibility with NEMA hole sizes and spacing: Panduit offers variants of this lug configured for different NEMA hole patterns to match diverse panel designs and grounding requirements. The availability of multiple hole sizes and spacings minimizes the need for adapters, streamlining field installations and reducing inventory complexity. The built-in inspection window remains a constant benefit across configurations, enabling technicians to verify proper seating quickly. This versatility makes the terminal connector suitable for a broad range of enclosures, grounding panels, and service upgrades in networks, manufacturing floors, and utility rooms while preserving a consistent, code-compliant grounding strategy.
• Industry-standard compliance and rigorous testing: This Panduit terminal connector is designed to meet critical standards used in network and telecommunications environments. It aligns with J-STD-607-A and TIA-942 grounding requirements, ensuring compatibility with modern data center and telecom infrastructure. The lug has undergone Telcordia testing and meets NEBS Level 3 criteria, a benchmark for equipment deployed in central offices and other network facilities. UL-listed status further confirms safety and performance compliance across jurisdictions. For engineers and technicians, these certifications translate into dependable grounding performance, predictable maintenance cycles, and reduced risk when deploying large-scale network systems.
• Durability and reliability for network environments: In high-demand settings—data centers, telecom rooms, industrial automation—the integrity of grounding connections is critical. The long-barrel, two-hole design minimizes conductor movement and distributes mechanical stress across a larger clamping area, helping resist loosening over time. The inspection window supports ongoing visual checks during routine maintenance windows, enabling quick detection of any seating issues without disassembly. This combination of robust termination geometry, inspectability, and certified performance contributes to lower downtime, fewer field failures, and improved overall system reliability in networks and critical electrical infrastructure.
• Ease of installation and maintenance: The lug is engineered for straightforward installation with common hand tools and standard hardware. Prepare the #10 AWG conductor, ensure clean and straight conductor strands, and insert fully into the lug seat. Align the 1/4" stud hole with the mounting stud and secure with the appropriate fastener to the manufacturer’s torque specification. The inspection window makes it easy to verify a complete seating, and the window view helps confirm there are no stray strands that could compromise the termination. The result is a dependable grounding connection that installers can trust across rack-mounted equipment, switchgear enclosures, and field installations with minimal need for specialty tooling.

How to Install Panduit Terminal Connector

• Before starting, ensure the entire system is de-energized and lockout/tagout procedures are in place per site requirements.
• Prepare the #10 AWG conductor by stripping insulation to the correct length and ensuring the conductor strands are clean, straight, and undamaged.
• Insert the conductor fully into the lug seating, taking care that no insulation remains under the clamping area and that the conductor is properly aligned with the lug bore.
• Place the lug onto the mounting stud or bus bar so that the stud hole aligns with the fastening point. Secure the lug with the correct nut or bolt, tightening to the manufacturer’s torque specification.
• Inspect the termination through the window to confirm full seating and clamping. Ensure there are no loose strands or gaps and that the connection is mechanically secure. If applicable, test continuity and grounding performance to verify a solid, code-compliant bond.
