Function of the ground wire in the distribution box
Every distribution box connects to a ground wire, which provides a safe path for stray electrical currents to flow into the earth instead of through circuits or appliances. The article discusses the importance and purpose of grounding in utility power transmission and distribution systems, focusing on how grounding helps mitigate issues like lightning strikes, line surges, high-voltage crossovers, and ground faults. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. This helps to reduce the potential difference that exists between conductive parts and the earth.
