About This Episode
In this episode, E&S Grounding Solutions President David Stockin explores the topic of resistance-to-ground specifications. It is important to consider the justification for specifying a particular value of resistance-to-ground. Can a very low value always be achieved? Does it matter? While some installations may have a valid need for a low resistance-to-ground, many times, it is not necessary. Also, consider that it is not possible to simply buy materials that meet an arbitrary resistance-to-ground spec. Rather, engineers should evaluate if the grounding system has a good continuity and therefore low potential difference across the system to minimize hazards to equipment and personnel.
