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.
