Panduit RGRB19Y StructuredGround 19" Rack Grounding Busbar Kit
NEC Article 250 and TIA-942 datacenter standards require permanent, low-impedance grounding infrastructure in equipment racks — temporary jumpers and shared frame grounds don't meet code and create ground-loop risk in multi-vendor installations. The Panduit RGRB19Y delivers a purpose-built tin-plated copper busbar engineered for 19" EIA-310-D racks, providing 14 discrete termination points for rack PDUs, cable managers, patch panels, and bonded equipment. Integrators installing head-end security racks, datacenter server rows, or telecom distribution frames get a UL 467-listed grounding bar that handles both imperial and metric hardware out of the box, eliminating the guesswork when bonding mixed North American and international equipment on the same rack.
Key Features
- 14 pre-drilled termination holes arranged for flexible conductor spacing and dual-sided access
- Tin-plated copper construction resists oxidation in high-humidity telecom closets and coastal installations
- Includes both #12-24 x 1/2" and M6 x 12mm thread-forming screws (two each) for universal equipment compatibility
- 19" (483mm) length matches EIA-310-D rack-mount width for clean single-RU or vertical rail mounting
- UL 467 and C22.2 No. 41-13 listed, meets EIA-310-D mechanical standard for rack-mount infrastructure
- 25mm (1") width provides substantial conductor contact area for #6 AWG and larger bonding conductors
The 14-hole pattern differentiates this busbar from typical 10-hole designs — in dense rack builds with 8+ powered devices (NVRs, PoE switches, rack PDUs, UPS units), the additional termination points prevent the "no room left" scenario that forces installers to double-stack lugs or daisy-chain grounds. Tin plating over the copper base delivers two critical benefits: it maintains a stable contact resistance over decades (copper oxidizes, tin doesn't), and it's galvanically compatible with both copper and aluminum conductors without creating dissimilar-metal corrosion cells. The thread-forming screws cut their own threads into the busbar holes, creating a gas-tight connection that meets UL's torque and pull-out requirements without needing pre-tapped holes or separate nuts — critical when you're working solo in a cramped rack and can't reach the back side of the bar. Panduit specs these screws for 10-12 in-lbs torque (standard for #12 and M6 hardware), which secures ring terminals on #10 through #6 AWG bonding conductors without over-torquing and cracking the copper.
This busbar integrates into TIA-942 Rated-3 and Rated-4 datacenter grounding schemes where each rack requires an isolated equipment ground bar bonded back to the central grounding busbar per ANSI/TIA-942-B section 8.2.2. In security integrator deployments, the RGRB19Y mounts vertically on rack rails or horizontally across rear knockout panels, bonding IP camera PoE switches, access control panels, and video management servers to a common point — then a single #6 AWG conductor ties the busbar back to building ground per NEC 250.96. The 19" length aligns perfectly with standard rack-mount holes (spaced 0.625" apart per EIA-310-D), and the 14-hole count supports up to 12 equipment bonds while reserving two corner holes for mechanical mounting. For head-end racks mixing Axis cameras, Bosch controllers, and HID panels — where you've got Swedish metric hardware, German DIN rail gear, and US-spec rack-mount PDUs — the dual imperial/metric screw kit means you're not hunting for adapters mid-install.
The StructuredGround sub-brand positions this bar within Panduit's broader rack infrastructure ecosystem: it bonds directly to their CMVHB series vertical cable managers and PDxxxx series intelligent rack PDUs without needing separate grounding jumpers, and the tin-plated finish matches the plating on their crimp lugs (LCD/LCDX series) to prevent galvanic mismatch. The UL 467 listing specifically covers "Grounding and Bonding Equipment" — not just generic hardware — which matters in projects requiring AHJ (Authority Having Jurisdiction) approval for electrical inspections, and the C22.2 No. 41-13 certification extends that approval into Canadian CEC installations.
