Should pay attention to deal with the common ground of the ground

grounding resistance - the common grounding pile grounding resistance should meet the minimum requirements of the grounding resistance in a variety of ground . To prevent mutual interference of the grounding system to ensure that the insulation of a building , the ground bus shall use a shielded wire with an insulating sheath , one end of the shielding sleeve grounding . DC , AC and safely end connected to pile on , but that does not mean they can be connected to a variety of places , should also be in accordance with the above requirements before its not connected to the same pile with each other should maintain strict insulation. Separate grounding of the computer equipment in DC with the chassis safely , their DC with rack strict insulation , respectively connected to pile on the appliance , but some computer chassis and DC together AC equipment with chassis strict insulation .
