What are the Top 3 Things the NEC Needs to Change?
In this Episode of Ask the Grounding Experts, E&S Grounding Solutions President David Stockin discusses the Top 3 areas of improvement that are needed in Article 250, the Grounding Section, of the National Electrical Code (NEC). In particular, the importance of installing a copper wire in branch circuits instead of using steel conduit is discussed. In addition, the human safety reasons for always bonding the steel rebar in concrete (concrete encased electrodes) and the need to use...

When Did the IEC Start Requiring Ground Rods?
In this episode, E&S Grounding Solutions President David Stockin discusses a requirement for ground rods in the IEC – it may be surprising to learn when this requirement was introduced! There are several reasons why a ground rod should be installed at every home’s electrical service panel, rather than rely upon the ground rod for the utility’s transformer. Sometimes when a code or standard introduces a new requirement, it raises a lot of questions on how to implement the requiremen...

What Are the Different Electrical Codes Around the World?
In this episode, E&S Grounding Solutions President David Stockin chats with us about electrical codes used around the world. Not every country and region follow the same standard or code, but most of these guiding documents derive their requirements from two main sources. These codes are frequently being updated as advancements are made in technology and safety. The E&S Grounding Solutions website maintains a helpful resource for engineers to find the codes in effect in nearly every p...

What Happens When Lightning Strikes a Tower (Part 2)
In this episode, E&S Grounding Solutions President David Stockin continues looking at an example of lightning striking a large metal tower. The connection between electrodes and earth will determine the potential difference across the ground, so it is important to understand what causes the potential difference and why engineers should work to minimize that difference. The formation of electromagnetic fields and step and touch voltages are other factors to consider in the design and analy...

What is the Curse of Resistance to Ground Specifications?
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 res...
