1). Absence of Grounding
Improper grounding might pose a significant risk. It raises the risk of electrical shock and fire.
2). Poor Soil Selection
The earth’s ability to disperse current is heavily influenced by soil quality. Rocky, dry soil equals high resistance and poor grounding.
3). Ignoring Soil Resistivity
Failure to verify soil resistivity before installation can result in inefficient grounding. Always measure it to select the appropriate earthing system.
4). Corroded (or) Loose Connections
Grounding may become ineffective as connections corrode or loosen over time. Regular inspection is essential.
5). Use Undersized Conductors
Thin (or) low-quality wires cannot safely handle fault current. Use conductors that correspond to the system’s fault level.
