Grounding terminal of the power distribution box at the construction site
Grounding of the units: Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). This helps to reduce the potential difference that exists between conductive parts and the earth. It includes overhead LV Mai s, Services and Meter boxes. 1 t his. Abstract: System grounding considerations affect many aspects of an electrical system. The voltage, system arrangement, loads connected, and continuity of. IPMENT, STRUCTURES, ETC. IN ELECTRICAL STATIONS INCLUDING TRANSMISSION AND DISTRIBUTION SUBSTAT GR THAN 8 FT FROM THE FENCE. THE FENCE SHALL BE GROUNDED SEPARATELY FROM THE GRID UNLESS OTHERWISE NOTED ON THE A PROPRIATE PROJECT DRAWING. Each DISTRIBUTION BOX and controller must be grounded. 7 Provide conduit grounding bushings, bonded together and connected to the equipment enclosure on all incoming and outgoing conduits on distribution switchgear and switchboards, distribution panels and on all conduits over 1-1/4” diameter at all panelboards, pull boxes and equipment.
