Home / Purpose of repeated grounding of the distribution box
Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. This helps to reduce the potential difference that exists between conductive parts and the earth. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Repeated grounding means that in a system where the neutral point is directly grounded, a metal wire is used to connect the grounding device at one or more places on the neutral main line.
Everything looks perfect until the moment of truth arrives. That''s why today we''ll break down the life-or-death details of grounding distribution boxes and cable shielding layers using plain
