Materials for grounding the three-level distribution box
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. A ground of all overhead line distribution equipment is always grounded and bonded to cont all be consider as a priority, if not available. Grounding is necessary to assure correct operation of electrical devices, to assure safety. This helps to reduce the potential difference that exists between conductive parts and the earth. Next, we describe directional elements suitable to provide ground fault protection in solidly- and low-impedance grounded distribution systems.
