Grounding ensures that all metallic parts of electrical equipment, including distribution boxes, enclosures, and cable armor, are at the same electrical potential, reducing the risk of electric shock and equipment damage. It also provides a clear path for fault currents, allowing protective devices to operate effectively . Key principles include:
Proper grounding of distribution boxes and cables involves:
