Burial depth of grounding electrode of construction site power distribution box
Where it is very difficult to drive the standard ground rod in soil / substation trench, Copper wire buried horizontally to a depth of at least 500 mm is considered equivalent to placing ground rods (6m of wire length equivalent to one rod). This Grounding Standard describes the technical requirements for grounding the SEC Distribution Network installations. 8 kV) feeder outlets of HV / MV Substations down to SEC Customer interface including KWH-Meters and meter boxes. Configuration: In terms of configuration, the grounding grid is normally composed of conductors that are buried at a certain depth below the ground surface and are interconnected in both horizontal and vertical directions. The 8-foot depth is a practical compromise that generally positions the electrode deep enough to engage with more stable soil layers. THE FENCE SHALL BE GROUNDED SEPARATELY FROM THE GRID UNLESS OTHERWISE NOTED ON THE A PROPRIATE PROJECT DRAWING. SEE APPLICATION "S",THIS DRAWING, FOR REQUIREMENTS FOR HIGH VOLTAGE TOWERS AND PO ES D BY GROUNDING ANALYSIS.
