WunderCurrent® Pure Copper Earthing Rod — Full Technical Information
The WunderCurrent® earthing system is built around a 6 mm C10100 pure copper grounding rod, the highest conductivity grade globally (up to 101% IACS conductivity). This ensures fast, stable, and safe grounding during EV charging.
Why External Earthing Is Important
- EV chargers require 5 ohms or better earthing for safe operation (as per BIS & Government of India electrical safety norms).
- Our C10100 copper rod typically achieves 3 ohms in normal soil.
- Actual results depend on soil moisture — coastal and humid areas deliver the best performance.
Copper Rod Design & Safety
- Sharp-pointed tip for effortless penetration into soil.
- Corrosion-resistant pure copper provides long-lasting grounding stability.
- Weatherproof & outdoor-ready for all Indian terrains.
Safety Warning:
- Never bypass the earthing requirement — it is unsafe and illegal in India.
- Avoid chargers sold in India that bypass earthing — they are not BIS compliant and may cause shock, fire, or EV damage.
- Always use proper grounding with your Wundercurrent charger.
