WebAug 4, 2024 · Leakage Current testing is used to verify that the product does not leak excessive current when contacted by the user. For medical equipment, the current flowing to ground is measured. Excessive leakage current can cause the heart to go into ventricular fibrillation resulting in cardiac arrest which can lead to death. Over time, corrosive soils with high moisture content, high salt content, and high temperatures can degrade ground rods and their connections. Despite low earth ground resistance values when initially installed, these values can increase if the ground rods are eaten away. Grounding testers, like the Fluke … See more The NEC, National Electrical Code, Article 100 defines a ground as: "connected (connecting) to ground or to a conductive body that extends … See more There is a good deal of confusion as to what constitutes a good ground and what the ground resistance value needs to be. Ideally a ground should be of zero ohms resistance. There is not one standard ground resistance … See more dhenu buildcon
