Quality Standards for Electrical Earthing or Grounding System in Building Constructions

 

 

Electrical Earthing or Grounding System for buildings to be carried out all in accordance with the international standards in conjunction with the local authority requirements and recommendations. Earthing standards and methods are highly depending on the nature of the utilities and equipment installed / used at the premises. Simple earthing system we provide to the domestic connections while complex systems are being used in the power stations and industries.


 

 


Medium and large scale building projects require simple system for residential areas and rest requires medium complex system. In most cases earthing integrate with lightning protection system and low current systems. Following are the most recommended and used standards across the world:
