I work for an electrical contracting firm in Nassau Bahamas. Presently we are in dispute with an egineering firm of the method of testing required for the grounding system for a well field project. The wells a distributed over a large area. The engineers are saying to use the fall of potential method. This will be highly impracticle due to the distances involved. We only need to achieve 5 ohms or less. Is this realy necessary?
