Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding of the units:A premise's wiring system supplied by a grounded service must have a grounding electrode conductor (GEC) connected to the service neutral conductor per Sec. 24 (A) (1) through (4): (1) General. The GEC connection to the neutral conductor at service equipment must be made at any accessible point. System grounding is the connection to the ground – solidly or through impedance – of current-carrying conductors – e. The purposes are to: ◦ limit overvoltages due to lightning, line surges, or. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical insights into proper grounding techniques, with a special focus on how selecting quality materials from a reliable building material supplier impacts your entire system's safety and longevity. A grounding electrode system creates a direct, low-resistance path between a building's electrical system and the earth.
Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor frames.
