Earth currents are very low-density electrical currents that can be detected in the soil. Earth currents are present in natural sources such as magma in the earth’s core or solar flares. Earth currents also exist in man-made sources including cable systems, plumbing, television antennas, street lights and household appliances because electricity must be connected to the earth (grounded) for safety. Earth currents from man-made sources have existed since the widespread use of electricity over a century ago.
There is no identified linkage between earth currents and human disease.
If electrical problems occur as a result of earth currents from faulted customer or utility equipment, the problems are easily detected and can be properly addressed.
You can take precautions by ensuring that any new installation or modification of existing wiring conforms to the National Electric Safety Code (NESC). In addition, all electrical system work should be performed by a state certified electrician to ensure the proper grounding.
We follow strict grounding requirements established by the Wisconsin Public Service Commission and support research to minimize earth currents.
