What are the regulations for the grounding wire of a secondary distribution box
26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Secondary equipment grounding refers to connecting the secondary equipment (such as relay protection and computer monitoring systems) in power plants and substations to the earth via dedicated conductors. Simply put, it establishes an equipotential bonding network, which is then connected to the. 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. It is a 4-wire system and the LV neutral is multiple grounded at all cable terminations, at MV / LV substations, distribution pillars, and consumer locations.
