Home / What is the normal grounding height for a distribution box
7 meters) high makes it easily accessible without the need to bend or stretch excessively. The proper installation of a distribution box involves placing it at the right height to ensure safety and convenience. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. 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.
