Copper Ground Clamp
🔎 What is a Copper Ground Clamp?
A Copper Ground Clamp is a mechanical device used to securely connect a copper grounding conductor to a grounding electrode such as a ground rod, water pipe, or structural steel. This connection ensures proper dissipation of electrical fault currents or lightning strikes into the earth.

🧱 Construction and Material
-
Material: High-conductivity copper, bronze, or copper alloys
-
Design: Usually includes a saddle or U-bolt design with screws or bolts for secure tightening
-
Coating: Often corrosion-resistant or tinned for outdoor/buried applications
-
Certifications: Typically UL 467 Listed and compliant with NEC (National Electrical Code)
⚙️ Function and Working
-
Ensures low-resistance path from the electrical system to earth
-
Prevents damage to equipment or structures from fault currents or lightning
-
Creates a permanent, mechanical bond between conductor and grounding electrode
🧩 Types of Copper Ground Clamps
| Type | Description |
|---|---|
| Pipe Ground Clamp | Attaches grounding wire to metal water or gas pipes |
| Rod Ground Clamp | Secures grounding wire to copper or galvanized ground rods |
| Heavy-Duty Clamp | Designed for industrial or high-amperage grounding systems |
| Universal Clamp | Adjustable for multiple conductor sizes and electrode diameters |
| Split Bolt Clamp | Used to splice two conductors or tap off a ground wire |
🏗️ Applications
- Residential and commercial electrical grounding

- Grounding of transformers, panels, and distribution boards
- Earthing water pipes, fences, and structural steel
✅ Key Features
- High electrical conductivity
- Strong mechanical hold
- Resistant to corrosion and weathering
- Compatible with a range of wire gauges and pipe/rod diameters
- Easy to install with basic tools
📐 Common Sizes and Wire Ranges
| Clamp Size | Pipe/Rod Range | Conductor Range |
|---|---|---|
| Small | 1/2" to 1" | #14 AWG – #6 AWG |
| Medium | 1/2" to 2" | #10 AWG – 2/0 AWG |
| Heavy-Duty | 1" to 4" | #6 AWG – 4/0 AWG |
📎 Installation Tips
- Clean the surface of rod/pipe before clamping
- Ensure clamp is tightly secured
- Use dielectric grease for long-term corrosion resistance (if needed)
- Avoid overtightening to prevent damage to conductor or clamp
