Grounding
pcThe process of connecting electrical equipment to the earth, reducing the risk of electric shock.
expanded
Grounding is a critical safety practice in electrical systems where it provides a reference point for electric currents to return to the earth. This is essential for protecting both people and equipment from electrical faults and ensuring the stable operation of power systems. Grounding systems are commonly implemented in residential, commercial, and industrial settings to prevent electrical hazards.
examples
An industrial motor control system utilizes an earthing system where each motor's frame is connected via a 10 mm² (0.0155 in²) copper conductor to an earth electrode with low resistance, typically less than 5 ohms.
This grounding configuration is used extensively in manufacturing plants to prevent electrocution and equipment damage during faults.
In residential wiring, the grounding conductor typically connects to a grounding rod, which is driven at least 2.4 meters (8 feet) into the ground, providing a secure path for fault currents in the event of a short circuit.
This method is commonly utilized in home electrical systems to ensure safety and compliance with electrical codes.
