Grounding of the distribution box using soft copper wire
When connecting the ground wire, a yellow-green insulated copper core soft wire with a cross-sectional area not less than the specified value should be used. This wire not only has good conductivity, but its yellow-green double-color outer skin also plays an obvious warning. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. 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.
