A good earthing system starts with proper installation procedure. Even a high-quality copper bonded earthing rod will not function to the best of its capabilities if it's not installed correctly. Regardless of whether you're earthing an industrial plant, commercial facility, or a solar project, the right installation procedure is key to safety as well as performance in the long run. Here in this blog, we have presented a step-by-step installation guide for installing copper bonded earthing rods successfully and as per IS/IEC standards.
Why Copper Bonded Rods?
Copper bonded rods are due to their:
✔ High conductivity
✔ Corrosion resistance
✔ Mechanical strength
✔ Long service life
They have no restrictions to soil and climate conditions, making them a top choice across various industries.
✅ Step-by-Step Instructions for Installing Copper Bonded Earthing Rods
Step 1: Site Selection and Soil Testing
Prior to installing, perform soil resistivity by the Wenner method or comparable. Select a site:
✔ Far from building foundations or underground lines
✔ With ideal moisture level
✔ Rock-free or free from debris that could impede driving
Step 2: Prepare Tools and Materials
You will require:
✔ Copper bonded earthing rod (usually 14 mm or 17.2 mm diameter, 2–3 meters long)
✔ Earth pit chamber and cover
✔ Ground improvement material (such as bentonite or GEM)
✔ Hammer, driving head, clamp, and coupler (if extending)
✔ Earth conductor (copper strip or wire)
✔ Megger or earth resistance tester
Step 3: Drive the Rod Vertically Into the Ground
By the help of hammer and driving head, drive the rod upright into soil vertically. In case of hard or rocky soil:
✔ Soften the soil with water
✔ Fit coupler to join rod with another section using a coupler
✔ Maintain minimum depth of 2.5 to 3 meters for industrial use.
Step 4: Join the Earth Conductor
✔ Clamp the copper wire or strip securely on the rod using an ISI-approved earth clamp.
✔ Ensure the connection is secure, corrosion-free, and has low contact resistance.
✔ For improved conductivity, apply brazing or crimping in high-current situations.
Step 5: Install Ground Enhancement Material
Fill the pit around the rod with ground enhancement material (GEM, bentonite, or charcoal & salt).
✔ This enhances conductivity in dry or high-resistivity soils.
✔ Leave at least 100 mm buffer space between the rod and the pit walls.
Step 6: Cover and Protect the Earthing System
Install a concrete earth pit chamber with a cover that can be removed. This:
✔ Protects the connection from tampering or weather
✔ Enables easy testing and maintenance
✔ Identify the pit with a label during inspection.
Step 7: Test Earth Resistance
Post-installation:
✔ Utilize an earth tester (Megger) to test the system resistance
✔ Ideal reading: <1 ohm for sensitive installations
✔ Log results for documentation and compliance.
Conclusion
Correct installation of a copper bonded earthing rod is necessary to ensure system safety, minimize fault current damage, and meet electrical codes. A step-by-step procedure guarantees low resistance, long life, and consistent performance of your grounding system.
