Grounding color of the outer casing of the third-level distribution box
Ground conductors for all power distribution equipment, end-use equipment and all branch circuits, shall be insulated stranded copper conductors, color coded green or (a continuous) green color with 1 or more yellow stripes. Abstract: System grounding considerations affect many aspects of an electrical system. This guide describes wiring color codes, international standards, and main rules to keep. This helps to reduce the potential difference that exists between conductive parts and the earth. An important element in protecting humans (as well as property and animals) from the effects of electric current is the grounding of the system—this involves the grounding of the point of the electrical supply system and the grounding of exposed conductive parts.
