When you compare the ConduDisc to conventional earth rods it becomes abundantly clear that the earth rod is yesterday’s technology. In fact it isn’t even yesterday’s technology, there have been far smarter and more effective solutions available for a few decades. Part of the reason that earth / ground rods have remained popular is because they are easy to understand what they are and how to install them. That being said “whack metal rod in ground” is often easier said than done, particularly in compacted ground, urban areas and rocky environments.
Earth / ground rods are causing growing health, safety and longevity causes in the construction world. Not only have RIDDOR reportable incidents associated with earth / ground rods increased, so too have investigations into failed earthing systems. In the eyes of proactive consultants and constructors earth rods represent too great a health and safety risk to permit to be installed, and the prospect of being liable for an earth system with unknowable service life represents too great a financial risk.
Then there’s the ConduDisc: as easy to install as dropping a stone in a hole, and has decades and decades of service life; at just 350mm x 50mm, this conductor has a contact surface area greater than 3m of earth rod, and yet fits easily in a small excavation. So long serving is the ConduDisc that it is highly likely to outlast the item for which it is providing an earth. It’s more effective and managing fault electrical current and more reliable. The health and safety risks associated with installing rods are removed so the prospect of RIDDOR fades away.
Rather makes earth / ground rods a bad idea on every front…
