Panduit RGRB19CN Grounding Bar

The Panduit RGRB19CN Grounding Bar is a premium 19-inch grounding solution designed to deliver fast, reliable earth bonding in electrical panels, enclosures, and equipment racks. With a tin-plated copper busbar that provides excellent conductivity and corrosion resistance, this grounding bar creates a solid, consistent grounding path for critical systems in industrial, commercial, and data-center environments. Its thoughtful engineering combines a compact 19" form factor with a flexible mounting pattern, making installation efficient and repeatable while ensuring compatibility with standard hardware and enclosure designs. Whether you’re updating legacy panels or equipping new installations, the RGRB19CN offers a dependable grounding interface that helps meet stringent electrical codes and bonding requirements while simplifying maintenance and serviceability.

• Optimized 19" form factor for universal compatibility: The 19" (483 mm) length is designed to fit standard electrical enclosures, equipment racks, and panel rails. The precise machining aligns with common mounting schemes, enabling straightforward integration into existing electrical architectures without requiring custom fabrication or adapters. This form factor helps streamline retrofits and new builds alike, reducing installation time and ensuring consistent grounding performance across multiple enclosures.
• Tin-plated grounding bar for durability and reliability: Tin plating on the busbar provides excellent resistance to corrosion and tarnish, extending service life in harsh environments. The tin finish also enhances bonding performance and solderability where temporary or service-oriented bonding is required, helping maintain a low-impedance ground path over the life of the installation. This makes the RGRB19CN suitable for industrial floors, manufacturing lines, and data-center environments where dependable grounding is essential.
• Twenty flexible mounting holes with precise spacing: The bar ships with twenty mounting holes arranged to offer flexibility in mounting orientation and conductor routing. The 5/8" (15.9 mm) hole spacing supports diverse installation scenarios, allowing technicians to align the grounding bar with existing studs, rails, or panel backs as needed. The ample hole density also supports distributing grounding conductors across the bar for balanced bonding and improved current distribution in high-density panels.
• Pre-installed hardware to simplify installation: Twenty #12-24 x 1/2" hex head screws are installed on the bar, reducing field assembly steps and ensuring uniform fastener torque. This turnkey feature minimizes the risk of missing hardware during installation and helps installers meet project timelines. The included screws provide a ready-to-bond path that remains stable under vibration and handling typical of industrial environments.
• Ready-to-bond accessories for secure grounding: The RGRB19CN includes two cage nut bonding studs and four #12-24 bonding nuts. These bonding accessories support reliable attachment to chassis and frame components, enhancing the mechanical and electrical integrity of the grounding path. The combination of bonding studs and nuts enables versatile bonding configurations, facilitating secure, low-impedance connections across multiple mounting points.

How to install Panduit RGRB19CN Grounding Bar

• Prepare the enclosure: power off the system, verify the area is safe, and ensure the mounting surface is clean, dry, and free of debris before starting the installation.
• Position and align: place the RGRB19CN in the intended location within the enclosure, aligning the twenty mounting holes with the designated mounting points or panel rails for a stable, level installation.
• Secure the bar: use the pre-installed #12-24 x 1/2" hex head screws to fasten the mounting holes. Tighten screws to the recommended torque to avoid loosening due to vibration while avoiding over-tightening that could strip threads.
• Attach conductors: land grounding and bonding conductors to the busbar as required by your bonding scheme. Ensure conductors are clean, properly terminated, and tightened to maintain a solid, low-impedance ground path.
• Verify bonding integrity: once installed, inspect all connections for proper seating, verify continuity to the enclosure ground, and perform a functional check to confirm reliable grounding across the system.
