Working Principle
The copper earthing electrode conducts leakage current, fault current, or lightning current safely into the ground. This maintains equipment at earth potential and ensures protective devices such as circuit breakers and fuses operate quickly during fault conditions.
Installation Guidelines
- Install the electrode vertically in moist soil whenever possible.
- Ensure firm contact between the electrode and surrounding earth.
- Use approved clamps and copper conductors for connections.
- Maintain the required earth resistance as per applicable electrical standards.
- Periodically inspect and test the earthing system to ensure proper performance.
