About This Episode
In this episode, E&S Grounding Solutions President David Stockin begins a discussion on testing the continuity of a grounding system, focusing on the two-point method. In this method, resistance measurements are made at numerous points in the facility, taking each measurement with the same reference point. One measurement between two points does not offer much information about the complex network on conductors in the grounding system. Taking readings in multiple locations will hopefully present consistently low values of resistance that will indicate the connections in the network of ground conductors are in good condition. Higher values of resistance may be indicative of an issue in the ground system connections. Continuity testing is also very important to ensure bonding conductors will serve their purpose to protect humans from harmful touch voltages.
