Home / 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.
Since copper wire is the standard against which other electrical wiring materials are compared, many publications and training activities address the proper installation of copper building wire systems.
