Distribution box lacks ground
Without proper grounding, there's a risk of electric shock or equipment damage. In modern power systems, distribution boxes are the core equipment for power distribution and control, and their stable operation is crucial to ensuring the safety and reliability of power supply. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. The grounding system provides a low-impedance path for fault current and limits the voltage rise on the normally non-current-carrying metallic components of the electrical distribution system. Preparation: First, you need to prepare some necessary tools, including grounding wire, grounding rod, voltmeter, insulating gloves and insulating tools.
