Panduit Grounding Bar

Enhance safety, reliability, and performance in electrical enclosures with the Panduit Grounding Bar. This 19" (483 mm) tin-plated grounding busbar is engineered for standard 19" racks and control panels, delivering a robust bonding path across equipment and chassis. Its fourteen mounting holes provide exceptional flexibility for diverse installation patterns, allowing technicians to tailor wiring layouts to the exact needs of their panels, whether upgrading existing systems or designing new ones. Supplied with two each #12-24 x 1/2" and M6 x 12mm thread-forming screws, it’s designed for quick, secure mounting with common hardware, reducing install time and ensuring dependable electrical continuity. Built to withstand demanding industrial environments, the Panduit Grounding Bar offers enduring corrosion resistance, consistent conductivity, and a reliable grounding solution for power distribution, automation, and control applications.

• Flexible mounting pattern: Fourteen pre-drilled holes arranged to support a wide range of mounting configurations, enabling engineers and technicians to optimize conductor routing, ease maintenance access, and adapt to varying enclosure footprints without custom modification.
• Comprehensive hardware included: Each packing includes two #12-24 x 1/2" screws and two M6 x 12mm thread-forming screws, providing compatibility with common enclosure frames, panels, and mounting rails for fast, tool-safe installation.
• Tin-plated corrosion resistance: The tin finish delivers durable protection against moisture, dust, and environmental contaminants while maintaining excellent electrical conductivity for a stable grounding path across the life of the equipment.
• Standard 19" form factor: Precisely sized to fit typical 19" rack systems and electrical enclosures, ensuring seamless integration with Panduit accessories and other manufacturer components used in panel builds and retrofit projects.
• Reliable grounding and bonding: Designed to provide a low-impedance ground path for multiple conductors, supporting bonding across chassis and enclosure metalwork, improving fault clearance reliability and reducing the risk of stray voltages in critical systems.

How to Install Panduit Grounding Bar

• Prepare the enclosure: Power down the system and follow lockout/tagout procedures. Ensure the enclosure interior is clean, dry, and accessible for mounting. This grounding bar is intended for indoor use within electrical panels and racks.
• Position the bar: Align the grounding bar along a suitable mounting surface such as a panel wall, rail, or chassis where space permits access to all fourteen holes. Verify that the bar is oriented to allow convenient termination of conductors while preserving airflow and easy inspection.
• Secure the bar: Use the included hardware or appropriate hardware compatible with your enclosure. Start with the two M6 x 12mm thread-forming screws and the two #12-24 x 1/2" screws in their preferred holes, tightening evenly to avoid distortion. Ensure the bar sits flat and parallel to the mounting surface for optimal bonding.
• Attach grounding conductors: Connect grounding and bonding conductors to the busbar terminals or clamps as required by your system design. Use properly rated lugs or clamps and ensure secure, clean connections to minimize resistance. Keep conductors neat and labeled for future maintenance.
• Verify electrical continuity: After tightening, perform a continuity check between the grounding bar and chassis or enclosure ground points to confirm a solid bonding path. A low-resistance reading indicates a proper connection; if resistance is unexpectedly high, recheck connections and mounting integrity.
• Finalize and test: Reassemble any panels, reapply covers, and run a functional test under normal operating conditions to confirm that the grounding path remains intact with the system energized in a controlled manner. Document the installation for maintenance records.
