What is Electrical Earthing or Grounding?
Earthing, also known as Grounding, is the process of connecting electrical systems, equipment, and devices to the ground (the Earth) to ensure safety and proper functionality in electrical installations. Earthing involves establishing a conductive path from the electrical system to the Earth’s conductive surface through grounding electrodes, conductive wires, and grounding conductors.
In other words, connecting the metallic (conductive) parts of an electric appliance or installation to the earth (ground) is known as Grounding or Earthing. The earthing or grounding system involves connecting the metallic components of electric machinery and devices to an earth plate (ground rod) or earth electrode via an earth lead (grounding conductor) buried in moist soil. This connection is established using a thick copper conductor wire with very low resistance for safety reasons.
Earthing, or grounding, is the process of connecting parts of electrical apparatus, such as metallic coverings and the earth terminals of socket cables, as well as stay wires that do not carry current, to the earth. Additionally, earthing involves connecting the neutral point of a power supply system to the earth to minimize the risk of danger during the discharge of electrical energy.
Note: As the terms Earthing and Grounding are used interchangeably, we will use both in the context of NEC and IEC for better understanding. Follow the local area codes such as NEC 250.52(A), 250.53, 250.66 250.122, IEC/BS EN 62561-2 and IEC (62305-3), BS-7671 & associated tables and IEEE standards related to the grounding and earthing)
