E&S Grounding Solutions President David Stockin responds to viewers' questions about the differences between ground “loops” and ground “rings”. Ground loops are a common term that is often ill defined and even more often used inappropriately. Typically, ground loops are used to define a process where the return currents (neutral currents) are allowed to travel back to the source on the normally-non-current-carrying-exposed-conductive-parts of a circuit, in violation of NEC 250.6 –Objectionable Currents. Objectionable Currents are hazardous to both persons and equipment and must be removed from any circuit.
