Thanks for contributing an answer to Electrical Engineering Stack Exchange! PDF Version. One of the first lessons new electricians learn is that electricity will always look for the path of least resistance to get to ground. A few of the more efficient grounding electrodes for buildings and structures are: A grounding electrode system is the connection to earth, through the code required grounding electrodes. If the voltage increases in a circuit, what happens to the current (amperes) if the resistance stays the same? How do I Find the Ground Fault? - Douglas Krantz In my country (Australia) we use an earthing system that looks like this: In case of an earth fault, the fault current path looks like: Note the connection between the earth bar and the neutral bar at the "MEN link". A Ground Loop is an unwanted electrical current path that can cause havoc in equipment or process control systems by introducing unwanted electrical noise. In household settings, grounding treats both the "symptom" and the "disease" in the event of an unanticipated accumulation of charges on the surfaces of appliances.

Chapter 40 Flashcards | Quizlet When this happens, the system is working, and all is right in the world. Supplies that have an output set of terminals and a separate ground can often be configured (by jumping ground to one . Article 100 of the NEC defines bonded (bonding) as connected to establish electrical continuity and conductivity. Bonding metal parts, such as enclosures and raceways, ensures that they are all continuous on an effective ground-fault current path (EGFCP) that references back to ground (earth).
