Panduit UGB2/0-414-8 Universal Ground Bar

The Panduit UGB2/0-414-8 StructuredGround™ Universal Ground Bar provides a UL 467-listed termination point for main equipment grounding conductors in control panels, electrical enclosures, data center racks, and industrial power systems. This 6-inch tin-plated copper bar accepts eight branch connections (#14–#4 AWG) plus a main grounding conductor up to 2/0 AWG via compression or mechanical connector, consolidating ground paths in a single compact assembly. Tin plating ensures long-term corrosion resistance and low-impedance contact in humid or industrial environments where bare copper would oxidize.

Key Features

Eight wire ports accept #14–#4 AWG branch conductors for distributed ground connections

Main lug accommodates 2/0 AWG equipment grounding conductor with compression or mechanical connector

Tin-plated copper construction resists corrosion and maintains conductivity over service life

Multiple mounting methods: bonding stand-offs for direct grounding, isolation stand-offs for separated ground planes, or direct panel mount

UL 467 listed and CSA 22.2 No. 41 certified for use in electrical panels and enclosures

6.04-inch overall length fits standard 19-inch rack mounting and compact enclosures

Ships with mounting hardware for immediate installation

Ground bar design matters in multi-device installations—every camera power supply, PoE switch, NVR, and access controller needs a low-impedance path to earth ground, both for equipment protection and to meet NEC Article 250 requirements. The UGB2/0-414-8 consolidates these paths without the daisy-chaining and loose terminal blocks that create resistance and compliance headaches. The eight ports handle individual equipment grounds while the 2/0 main lug connects to your building ground grid or service entrance. Tin plating is critical here: unlike bare copper, which forms a resistive oxide layer in weeks, tin maintains milliohm-level contact resistance for years, even in coastal or industrial atmospheres. This is the difference between a ground system that passes inspection today and one that still works in ten years.

Mounting flexibility solves real cabinet layout problems. Bonding stand-offs ground the bar directly to the enclosure, creating a single-point ground when the panel itself is your reference. Isolation stand-offs separate the bar from the enclosure, necessary when you're running separate signal and power grounds or when the cabinet is mounted on a non-conductive surface. Direct mount works for DIN rail panels or when you're tight on depth. The UGB2/0-414-8 handles all three without requiring a different part number, so you can stock one SKU for mixed deployments. Common applications include security system head-end racks (where you're grounding multiple power supplies, network switches, and UPS units), access control panels (grounding strike power supplies and controllers), and industrial control cabinets where PLC power and I/O grounds must remain separated until the ground bar.

UL 467 listing confirms this bar meets the mechanical strength, current-carrying, and temperature-rise requirements for grounding and bonding equipment—meaning it won't fail under fault current or loosen under thermal cycling. CSA 22.2 No. 41 certification extends that compliance to Canadian installations. The 10-pack carton quantity reflects typical project scale: a mid-sized access control or surveillance deployment might use two to three bars (one per equipment rack or remote power cabinet), making the carton a convenient stock unit for integrators running multiple jobs. This is a foundational component—every rack with more than two powered devices needs one, and specifying a listed, tin-plated bar up front avoids the service calls and reinspections that come from using hardware-store ground straps or bare copper bus bars that corrode out.
