Panduit GTC2/0-L Flat Surface Grounding Clamp — 2/0 Solid, 50-Pack
Overview
The Panduit GTC2/0-L is a flat-surface grounding clamp engineered for utility and ground grid applications where a reliable, code-compliant mechanical bond is non-negotiable. Part of the Panduit StructuredGround™ grounding and bonding line, this clamp ships in a 50-unit pack, making it a practical choice for projects requiring multiple termination points across a ground grid. At 2 inches tall and 1.15 inches wide, it fits standard flat-surface mounting geometries without requiring custom adapters.
Key Features
- Copper Alloy/Tin Construction: The tin-plated copper alloy body resists corrosion at the interface — critical in utility environments where dissimilar-metal contact or moisture exposure would otherwise degrade the grounding bond over time and introduce resistance at the termination point.
- cULus Listed to UL467 and CSA 22.2 No.4: Compliance with both UL467 and CSA 22.2 No.4 means this clamp satisfies the grounding standards required for US and Canadian electrical installations. If your project requires documented code compliance for the AHJ, this listing covers it — you are not relying on an unlisted equivalent.
- Utility/Ground Grid Application Rating: Rated specifically for utility and ground grid use, not just light commercial bonding. This matters when specifying for substations, outdoor equipment pads, or infrastructure grounding where the termination will carry fault current.
- Compact Footprint (2 in H × 1.15 in W × 1.75 in L): The compact envelope fits tight panel and enclosure grounding lugs without clearance conflicts, which is a real consideration in dense equipment rooms or switchgear lineups where every inch counts.
- 50-Unit Pack Quantity: The GTC2/0-L (often searched as GTC2/0 L) ships in packs of 50, matching the quantity breaks common in ground grid projects. Ordering by the pack keeps unit cost down and ensures you have spares on site for rework without a separate procurement run.
- StructuredGround™ System Compatibility: As part of Panduit's grounding and bonding product family, the GTC2/0-L integrates with the broader StructuredGround™ ecosystem — useful when you need a consistent, documented grounding system across a facility rather than mixing clamp manufacturers and risking compatibility questions during inspection.
Integration and Compatibility
The GTC2/0-L is designed for 2/0 solid (SOL) conductor terminations on flat grounding surfaces. Installers specifying this clamp for mechanical grounding connectors should verify conductor gauge and surface geometry against the manufacturer's dimensional data before ordering. The competitor cross-reference GC2626CT is noted in manufacturer data — if you are replacing or standardizing away from that part number, the GTC2/0-L is the direct Panduit equivalent in this family. For broader grounding system planning, pairing with compatible Panduit StructuredGround™ components ensures consistent torque specs and listed assembly documentation.
Frequently Asked Questions
Q: What conductor size does the GTC2/0-L accommodate?
A: The GTC2/0-L is rated for 2/0 solid (SOL) conductors on flat grounding surfaces.
Q: Is the GTC2/0-L cULus listed?
A: Yes. The GTC2/0-L is cULus listed to UL467 and CSA 22.2 No.4 for grounding applications, covering both US and Canadian code requirements.
Q: How many clamps come in a package?
A: Each package contains 50 units of the GTC2/0-L.
Q: What material is the GTC2/0-L made from?
A: The clamp body is copper alloy with a tin plating, which resists corrosion at the termination interface in utility and outdoor environments.
Q: What is the overall size of the GTC2/0-L?
A: The GTC2/0-L measures 2 inches tall, 1.15 inches wide, and 1.75 inches in overall length.
Q: What applications is the GTC2/0-L rated for?
A: It is rated for utility and ground grid applications — suitable for substations, outdoor equipment pads, and infrastructure grounding where a code-listed mechanical bond is required.
When I spec grounding hardware for utility and ground grid work, the two things I want documented before anything leaves the submittal: listed status and material. The GTC2/0-L checks both — cULus listed to UL467/CSA 22.2 No.4, copper alloy/tin construction, and it ships in 50-packs so you are not rationing clamps on a multi-point ground grid installation.
Technical Highlights:
- Dual Listing (UL467 / CSA 22.2 No.4): Covers both US and Canadian jurisdictions in a single part number — no need to stock separate listed parts for cross-border projects or facilities with mixed inspection authorities.
- Tin-Plated Copper Alloy Body: Tin plating at the interface slows galvanic corrosion where the clamp contacts the grounding surface — a meaningful durability factor on outdoor utility pads where bare copper would oxidize and add resistance at the bond point over time.
- Compact Envelope (2 in × 1.15 in × 1.75 in): Fits tight switchgear and panel grounding lugs without clearance conflicts — the kind of spec detail that prevents a field rework call when a larger clamp won't seat.
Deployment Considerations:
- Confirm the termination surface geometry matches the flat-surface design before ordering — this clamp is not rated for round conductors or curved surfaces; wrong geometry will compromise the mechanical bond and potentially void the listing.
- The 50-unit pack quantity (UPC 07498307055) is the only pack size in evidence — if your project requires fewer than 50 terminations, factor the overage into your material cost estimate upfront.
The GTC2/0-L is the right call for utility infrastructure and ground grid projects where the AHJ will pull submittals and verify listed hardware — specifically substations, equipment pads, and outdoor switchgear installations requiring dual US/Canadian code documentation on every grounding termination point.
