Component Specifications

Definition
A mechanical component designed to establish a low-resistance electrical connection between an earth electrode (e.g., rod, plate) and the grounding conductor. It ensures mechanical stability and electrical continuity, often made of corrosion-resistant materials to withstand environmental conditions.
Working Principle
The clamp or connector applies compressive force to create a metal-to-metal contact between the electrode and conductor, minimizing contact resistance. It may use bolts, springs, or wedges to maintain pressure over time.
Materials
Typically copper, brass, stainless steel, or galvanized steel; often with tin or nickel plating for corrosion resistance.
Technical Parameters
  • Bolt Torque 20-50 Nm
  • Conductor Range 2-300 mm²
  • Temperature Range -40°C to 105°C
  • Contact Resistance <0.001 ohm
Standards
IEC 62561-1, UL 467, BS EN 62561-1
